ERN · A Research Primer

What you should know about eviction.

An eviction record marks the moment a household nearly lost one of its most basic protections: a place to live. It rarely tells you what happened next — whether the family stayed or was pushed out, where they went, or what it cost them. This primer assembles what the research does establish: how eviction is measured, why people fall behind, who carries the burden, how the clock runs differently in every state, what an eviction does to the people who live through it, and what is shown to work.

The Record

An eviction record says a household almost lost its home. It rarely says what happened next.

An eviction is, at bottom, the legal removal of a renter from their home. But the word covers a much wider event than the court case that carries its name. The case begins when a renter falls behind: the typical case is filed for nonpayment of rent, and 90% of evicted tenants owe at least a month of rent when they are removed. What it does not record is the question that matters most for the family: did they manage to stay, or were they displaced?

Two households with identical court records can live completely different lives afterward. One negotiates, pays what they can, and keeps the apartment. The other packs up — sometimes before a judge ever rules — and begins the search for somewhere they can afford, near work, near a child's school. The record looks the same. The outcome does not. Eviction data tells you that a household reached the edge of losing a fundamental need. It does not tell you whether they fell.

That gap is the first thing to understand about eviction numbers, and it shapes everything that follows. The figures on this page describe a system under enormous strain. They cannot, on their own, describe the life of any one family inside it.

The reason a case is recorded — nonpayment — is almost never the whole reason. It is the charge that stuck.

A nonpayment filing records the most easily proven fact — money owed — but rarely the full context around it. Behind a single filing can sit a rent increase, a change in management, an unresolved repair request, a dispute, a new child, a disability, a building-code complaint. The court writes down only the dollars.

The Iceberg

For every eviction a court records, several more happen off the books.

The court filing is the tip of the iceberg. Most forced moves never reach a courtroom at all. Nationally, researchers estimate roughly 5.5 informal, forced moves for every formal court eviction — landlords who change the locks, refuse to renew, raise the rent past reach, threaten, or simply tell a tenant to leave before any paperwork is filed. An earlier study in Milwaukee put the ratio at about 2 to 1. The true figure varies by place, but the direction is settled: what the courts capture is a fraction of what actually happens.

Figure 1

Court records capture the visible tip. Most forced moves stay below the surface.

An iceberg diagram of eviction A small tip above the waterline represents formal court evictions — about 3.6 million cases filed and roughly 1 million eviction judgments each year. A much larger mass below the waterline represents informal and forced moves, estimated at about 5.5 times as many, most of which are never recorded. WHAT COURT RECORDS SEE WHAT THEY MISS Formal court eviction ~3.6M filings · ≈1M judgments / year Informal & forced moves lockouts · non-renewals · threats · "voluntary" exits about 5.5× as many — mostly unrecorded
The ratio is a range, not a constant. 5.5 informal moves per formal eviction is the national estimate from the 2017 American Housing Survey; the 2:1 figure is from Milwaukee. Both count forced moves — not voluntary ones.
Sources: Gromis & Desmond, Cityscape 23(2), 2021 (national, 5.5:1); Desmond & Shollenberger, Demography 52(5), 2015 (Milwaukee, 2:1); national filing/removal counts from Gromis et al., PNAS 2022 and the Eviction Lab.

There is a second reason the count runs low: an eviction is not a single event but a chain of data points, and the public record only begins partway down it. A renter first gets a notice; if they don't pay or leave, the landlord files an unlawful-detainer case; if the renter doesn't respond or loses, the court enters a judgment and issues a writ, and a sheriff carries out the lockout. The crucial fact: a renter can move, pay, or settle at any of these points — and most do, well before the end. So each data point captures fewer people than the one above it.

Figure 2

The data points of an eviction — what each one is, whether it's counted, and where renters leave.

In New York City in 2017, owners filed 230,071 eviction cases — but city marshals carried out 20,804 lockouts. That is roughly 11 filings for every removal: most cases end somewhere in between.

Informal moves & non-renewals No court case at all — the largest, most invisible exit.
Not recorded
Most displacement happens here, before any paperwork.↘ renters move before a record ever starts
Notice to pay or quit The landlord's written demand. Starts the legal clock.
Rarely recorded
Almost no jurisdiction logs notices. Los Angeles (since 2023) and San Francisco run rare public registries; Washington counted notices statewide in a 2021–23 pilot.↘ renters pay, negotiate, or move out
Court filing — unlawful detainer The landlord sues. ~3.6M cases a year. The public record begins.
Recorded
The data most research relies on — though some states (e.g., California) seal it.↘ renters settle, move, or never respond
Judgment The court grants the landlord possession — roughly 1M a year in court-record estimates.
Recorded
Many judgments are never carried out — the renter has already gone.↘ renters vacate before a forced removal
Writ & lockout A sheriff removes the household. No national count exists.
Smallest · last
The most concrete number — and the smallest. It misses everyone who left earlier.▪ the end of the line — most cases never reach it
Renters move at every stage, so the last, smallest number — sheriff lockouts — is the bottom of a funnel that has already shed people at every step above it. Reading it as "the number of evictions" undercounts displacement many times over.
Sources: filing/removal counts from Gromis et al., PNAS 2022 and the Eviction Lab; 11:1 filing-to-lockout ratio computed by the NYC Council Data Team from Office of Civil Justice filings and Department of Investigation marshal data (2017); notice-registry and record-sealing detail from ERN field research and state statutes.

One more dynamic hides cases from view: the same household is often filed against again and again. For many landlords, an eviction filing is a routine rent-collection tool, not a final decision to remove anyone. Most filings never end in a lockout. This is why a single year's filings and a single year's removals describe different things — and why the threat of eviction reaches far more families than the eviction itself.

The Trigger

Nine in ten evicted tenants owe back rent. The trigger is usually one bad month.

It is tempting to imagine the evicted tenant as careless. The data describes someone else: a working household one shock away from the edge. About 90% of evicted tenants owe at least a month of rent when they are removed, and the typical amount owed at move-out is around $1,250 — roughly one and a quarter months' rent. People are not evicted because they stopped trying. They are evicted because a thin margin gave way.

~90%
of evicted tenants owe at least one month of back rent at move-out (NBER, 2024)
$1,252
typical back rent owed at move-out — about 1.25 months' rent (NBER, 2024)
37%
of U.S. adults could not cover a $400 emergency with cash on hand (Federal Reserve, 2024)

That last number is the engine. When more than a third of adults cannot absorb a $400 surprise, the distance between "current on rent" and "in eviction court" is a single car repair, a cut shift, an emergency-room bill. In one ERN study of tenants in eviction, a large share carried recent medical debt. The causes stack: income that swings week to week, a layoff six months earlier, a health crisis. The rent is simply the bill that comes due first and most visibly.

And the sums are often smaller than people assume. Many eviction cases are filed over modest amounts — sometimes a fraction of a month's rent — even though missed months can compound the total by the time a household is removed. Sometimes the unpaid rent is itself tied to the condition of the home: mold, a broken furnace, an air-conditioner that can't keep up with a Central Valley summer, a repair left undone. The ledger records none of that. It records the shortfall.

The point Eviction is, first and most reliably, a measure of poverty — of incomes that no longer reach rents. It rises and falls with the gap between what households earn and what housing costs, the gap that decides who has a cushion and who does not.

The Burden

Black renters are 19% of renters and 51% of those threatened with eviction.

Eviction does not fall evenly. In the first study to link eviction cases to individual Census records nationwide, Black renters made up 18.6% of all renters but 51.1% of everyone threatened with eviction, and 43.4% of those actually removed. About 1 in 5 Black renters is threatened with eviction in a given year, and roughly 1 in 10 is evicted; for white adult renters, the same study puts the annual filing rate at 4.2% (about 1 in 24) and the eviction rate at 2.5%.

Figure 3

Read it as a gap. If eviction fell evenly, all three bars would sit near 19%. The filing and removal bars climb far above the renter share — the disparity is in who the system pulls in.
Source: Graetz, Gershenson, Hepburn, Porter, Sandler & Desmond, "A comprehensive demographic profile of the US evicted population," PNAS 120(41), 2023 — ~38 million cases linked to Census records.

The disparity sharpens at the intersection of race and gender. In a study of nearly 1,200 counties, Black women faced an eviction-filing rate of 6.4% — nearly double the 3.4% rate for white women. The sociologist Matthew Desmond's summary has become the standard shorthand: in disadvantaged neighborhoods, eviction is to women what incarceration is to men — incarceration locks men up, while eviction locks women out.

Two cautions keep the picture honest. First, court records measure only formal eviction. For Latino renters — including many immigrant families — the national filing rate looks close to that of white renters, but court data cannot capture informal moves that never reach a courtroom — and the study itself cautions that rates for Hispanic and Asian renters may be biased downward because households without Social Security numbers cannot be linked to court records. Second, eviction is no longer only an urban story: the suburban share of evictions rose in 59 of 74 large metros between 2000 and 2016. The map of risk is shifting outward.

Where ERN can see addresses, the pattern holds: filings concentrate in rent-burdened, highly segregated neighborhoods.

Where states let us geocode cases — Oregon, Minnesota, Indiana and others — the filings cluster in the same places each time: neighborhoods that are historically Black and Latino, carry high rent burden, and remain residentially segregated. Where records are sealed or addresses withheld, we cannot see it directly. But the consistency of the pattern everywhere else is itself evidence of where the burden is most likely landing.

The Clock

From overdue rent to a lockout runs about a week in the fastest state and two months in the slowest. And it's built differently in every one.

"Eviction" is not one process — it is four phases that every state assembles in its own way: a grace period (in a few states), a notice period, a court phase from filing to judgment, and a post-judgment window from the judgment to the sheriff's lockout. ERN compiled the typical clock for all fifty states and the District of Columbia. End to end it runs from under a week to about two months — but two states with the same total can get there by very different routes.

Figure 4

The anatomy of an eviction: four phases, six moments, one shrinking window for the renter to act.

The four phases of an eviction, from overdue rent to lockout A horizontal timeline of an eviction's four phases. A grace period (0 to 15 days, in a few states) and a nonpayment notice period (0 to 14 days) make up the renter's window to pay, cure, or move. Then the court phase from filing to judgment (statutory minimums of 0 to 30 days), and the post-judgment phase from judgment to the sheriff's lockout (0 to 23 days). Key moments along the way: rent due, notice served, landlord files, hearing or answer deadline, judgment, and lockout. The renter can pay, settle, or move at any point, but the window narrows as the case advances. RENT DUE → LOCKED OUT · THE FOUR PHASES About 5 to 56 days, end to end. Notice served pay · cure · move Landlord files case opens in court Hearing / answer due Judgment order of possession Lockout sheriff removes; locks change Rent due · day 0 GRACE 0–15d · few states NOTICE 0–30 days COURT · filing → judgment 0–23 days POST-JUDGMENT · → lockout 0–22 days The renter can pay, cure, or move — and respond in court After judgment, removal proceeds automatically A renter can move, pay, or settle at any point — most leave well before the lockout.

CourtFiling → judgment0–30Yes
Post-judgmentJudgment → lockout0–23Yes
Every eviction runs through the same four phases — but the lengths differ enormously by state. The renter's clearest window to act is early (grace and notice); during the court phase they can still respond, settle, or move; after judgment, the removal proceeds on its own. The next figure shows how each state assembles these phases.
Phase ranges are statutory minimums from the ERN verified time-to-evict dataset (rebuilt from each state's statutes and court rules, July 2026), cross-referenced with the LSC × Temple Eviction Laws Database. In 34 of 51 jurisdictions the law sets no upper limit.

How a state spends those days varies as much as the total. Some front-load the notice period; Massachusetts, Oregon, and Vermont have the longest court phases; Pennsylvania and D.C. pile most of the days after the judgment, in the wait for the sheriff. The full state-by-state chart — every phase, every citation, every effective date, sortable — lives on its own page:

State Eviction Timeframes
The verified statutory clock for all 50 states and D.C.: floors of 5–56 days, ceilings only where the law sets one, per-stage citations and effective dates, and a downloadable dataset. Louisiana and West Virginia can lawfully reach a lockout in about five days; Massachusetts takes about two months.

A renter's odds depend enormously on which of these fifty-one clocks they happen to live under — and on how the days are arranged within it. A long notice period is time to find rent or a lawyer; a long post-judgment window is time to plan a move. The same total can be far more, or far less, survivable depending on where the days fall.

A research-network footnote One caution: these are typical, statutory clocks — what the law and common practice allow. What courts actually do, with backlogs, continuances, and re-filings, runs longer and is largely unmeasured. No federal agency publishes national eviction statistics, and the field's leading datasets capture filing and judgment counts, not elapsed time (Gromis et al., PNAS 2022; Thomas et al., Cityscape 2024). Building the instrument to measure the real clock is exactly the gap ERN exists to close.

The Cost

An eviction filing raises a tenant's risk of death by 19%. A judgment raises it by 40%.

The harm of an eviction is not confined to the day of the move. Linking renters from the 2000 Census to 38 million eviction court records and administrative death records, researchers found that simply having an eviction filed against you was associated with a 19% higher risk of death in the following years; having a judgment entered against you, with a 40% higher risk. Eviction does not just follow hardship — it deepens it.

Figure 7

Think of it as a stress thermometer — each stage adds load.

An eviction stress thermometer A vertical scale showing how stress and disruption accumulate through the eviction process: a notice arrives, a case is filed, a judgment is entered, a lockout is carried out, and the household is forced to move — each stage adding new burdens. Notice arrives Time and attention pulled from work, kids, rest. Case filed A public record begins — the "Scarlet E." Judgment Hearing, possible loss, mounting debt. Lockout Removal by the sheriff; belongings out. Forced move New home, new school, lost network — at once.
An eviction can set off three or four major life events at the same time — a move, a school change, a lost job, a severed support network — each compounding the next.

Beyond health, the record itself becomes a barrier. Tenant-screening companies scrape court files and flag anyone named as a defendant — even tenants who won their case or had it dismissed. Roughly one in five eviction records carries ambiguous or misleading outcome information, and these flags can follow a renter for up to seven years. Researchers call it the Scarlet E: a single filing can quietly block the next apartment, long after the dispute is over. California seals eviction records partly to prevent exactly this — but sealing cannot erase the stress already absorbed.

The downstream costs ripple outward: eviction is a leading pathway into homelessness; it is associated with job loss; it pushes families into higher-poverty, higher-crime neighborhoods than they would otherwise choose; and the presence of children, rather than protecting a household, is associated with higher odds of an eviction judgment. The move is rarely just a move.

What Works

Where tenants get a lawyer, most stay housed. Nationally, almost none have one.

This is the part the data is most hopeful about: evictions are not weather. They respond to policy, and several interventions have a measurable record. Start with representation. In eviction court, the sides are profoundly unequal — nationally only about 4% of tenants have a lawyer, against 84% of landlords — the National Coalition for a Civil Right to Counsel's average across roughly forty local studies, absent a right to counsel. The gap shapes outcomes before a word is spoken.

Figure 8

In eviction court, one side almost always has a lawyer. The other almost never does.

PartyRepresented
Landlords84%
Tenants4%
Closing that gap changes outcomes. After New York City became the first U.S. city to guarantee tenants a lawyer (2017), 84% of represented tenants stayed in their homes in the program's early years (72–93% by borough since). Washington became the first state to do the same in 2021.
Sources: National Coalition for a Civil Right to Counsel (representation gap, 2026); NYC Office of Civil Justice via NCCRC (84% remained housed).

A lawyer is not magic — it is navigation. Eviction is a civil case, so there is no public defender; a renter facing a seasoned landlord attorney is usually negotiating alone, often without understanding the process. Many never appear at all: across New York State courts, 54% of nonpayment filings went unanswered by the tenant (2016–mid-2022) — and while a default judgment requires the landlord's request rather than following automatically, defaults account for a full 40% of the eviction warrants the state issues. Representation closes that gap, and where tenants get it, large majorities reach a favorable outcome and most keep their homes.

The largest test of the money side is now published. ERN and the Housing Initiative at Penn evaluated the pandemic's $46.55 billion Emergency Rental Assistance program for HUD — Keeping People in Their Homes (2026) — using filing records, Treasury payment data, and household surveys across 16 states. Counties that received more ERA saw fewer filings, especially where unemployment and rent burden ran high, and fact-based proxy rules that cut application paperwork amplified the effect. In the case-study cities, Los Angeles delivered nearly $2.4 billion to 181,117 households and Philadelphia over $235 million to 31,335; assisted tenants had 53% lower odds of moving (Los Angeles) and about 65% lower odds of street homelessness. One finding reaches beneath the court data entirely: assisted households had 45% lower odds of a forced move with no court process — rental assistance suppresses the informal evictions of Figure 1, not just the filings. Across the study counties, filings from March 2020 to early 2022 ran about 45% below pre-pandemic forecasts — roughly 673,000 fewer — the combined force of moratoriums, state protections, and ERA together.

But a lawyer alone leaves the underlying problem — the unpaid rent — in place. The most effective combination pairs counsel with money. In Phase 2 of Philadelphia's pre-filing diversion program, just 4.2% of cases that reached a mediated agreement and received rental assistance went on to face an eviction filing within six months, against 42.2% without assistance — though over 21 months the assisted rate rises to 33.3%, a sign assistance sometimes delays rather than fully prevents. Prevention beats litigation: the gold standard is stopping an eviction before it is ever filed.

ERN organizes the evidence as four P's, ordered from fastest-acting to slowest:

P

Prevent

Tier 1 · most immediate
  • Emergency rental assistance
  • Pre-filing mediation / diversion
  • Right to cure (pay and stay)
P

Protect

Tier 1–2
  • Right to counsel
  • Just-cause eviction rules
  • Source-of-income & record-sealing protections
P

Preserve

Tier 2–3 · slower
  • Keep existing affordable units affordable
  • Anti-displacement zoning
  • Acquisition of at-risk housing
P

Produce

Tier 3 · longest horizon
  • Build new affordable housing
  • Expand subsidized supply
  • Sustained public investment
What we know What works is no longer the open question. A decade of evaluations points the same way — legal representation, rental assistance, diversion, and fair-screening rules all show measurable results, and several return far more than they cost: a 2018 Stout analysis for Philadelphia projected roughly $12.74 returned for every $1 spent on tenant counsel. The unsettled question is implementation — whether a given state or city is willing and able to adopt and fund them. A statewide right to counsel, for instance, is proven; as of 2026 it exists in roughly five states and about two dozen cities. The evidence is not the constraint. Capacity, cost, and political will are.

The strongest single combination on the evidence is a Prevent tool (rental assistance) paired with a Protect tool (right to counsel). While pandemic protections were in force, filings across the 6 states and 31 cities the Eviction Lab tracked fell to less than half of normal — 65% below average from March 15 to December 31, 2020 — bolstered by the $46.5 billion in emergency rental assistance Congress appropriated; when that one-time money lapsed, filings climbed back toward, and in some places past, pre-pandemic levels.

Part II · The Research

The primer above is what we know. This is how we know it — and where the data breaks.

Part I describes the eviction system in plain terms. Part II is for readers who work with the numbers: how households actually move through — and off — the legal ladder, why counts cannot be compared across states, what the record marks and what it misses, how eviction sits inside displacement at large, and who is building the data infrastructure to fix all of it. Every claim carries its citation in the sources.

The Ladder, Measured

Two-thirds of Chicago filings end in an eviction order. Barely a quarter of those orders end with a sheriff at the door.

The funnel in Figure 2 is not hypothetical. Where researchers have linked court records to what actually happened, the attrition is dramatic: in Cook County, about 65% of eviction cases end with an eviction order, and the Sheriff's Office executes about 26% of those orders — roughly 17 filings in 100 end with a forced removal. In New York City, about 35% of nonpayment cases end in an order and 31% of orders are enforced by a marshal — roughly 11 in 100, with around 64% of non-order cases ending in settlement (Collinson et al., Quarterly Journal of Economics, 2024). Baltimore is the extreme: a rent court processing roughly 150,000 complaints a year produced about 6,500–6,900 completed evictions — under 5% of filings (Justice Diverted, 2015).

The harm does not wait for the sheriff. The same linked-records research finds an eviction order raises the probability of emergency-shelter use by 3.4 percentage points and of appearing at a new address by 8.2 points within a year, with effects concentrated among Black and female tenants — and long-run damage to credit and debt that outlasts the case.

A filing is a threat recorded; a judgment is a loss recorded; a lockout is a removal recorded. Three different measures of three different things.

Incomparable Counts

Baltimore City logged 144,058 filings the same year King County logged 4,788. Baltimore did not have thirty times the eviction problem.

In fiscal 2017, Maryland's courts recorded 144,058 landlord–tenant filings in Baltimore City (Maryland Judiciary). In calendar 2017, all of King County, Washington — Seattle included, with a far larger population — recorded 4,788 unlawful detainers (Losing Home, 2018). The 30× gap is not a gap in hardship; it is a gap in process. For decades Maryland required no notice before filing, charged $15 to file, and set trial for the fifth day — the court filing was the late-rent notice, refiled monthly as routine rent collection, a practice landlords themselves describe as working "by redefining renters as debtors" (Garboden & Rosen, 2019). Nationally, 44.6% of filings in 2014 were serial refilings against the same household; in Maryland, 57.4% (Leung, Hepburn & Desmond, 2021; Gromis et al., 2022). Maryland added a 10-day pre-filing notice in October 2021, and statewide filings fell by more than half.

This is why the state timeframes table is the decoder ring for any eviction count: where the count is taken in each state's process determines what the count means. A "filing" in pre-2021 Baltimore is roughly what a pay-or-quit notice is in Seattle — and notices are exactly what most states never record.

The Notice Gap

Where notices are actually counted, they outrun filings at least two to one.

Only a handful of places count eviction notices at all. Los Angeles has required landlords to file every notice with the city since February 2023: 290,560 notices in its first three years and two months — roughly double the county's unlawful-detainer filings over the same window, and a hard floor, since the notices cover only the city while the filings cover the county (LA Controller; Judicial Council of California). Washington ran the only statewide notice census to date, a 2021–23 pilot that logged 158,251 pay-or-vacate notices — more than 7,000 a month in a state that filed 15,000–20,000 eviction cases a year before the pandemic; the courts' own report called the volume "significantly higher... than anyone understood." San Francisco is the caution: its registry excludes nonpayment notices, so filings there exceed registered notices — registry design decides what you see.

Set against Figure 1's estimate of 5.5 informal forced moves per formal eviction, the arithmetic compounds: filings sit midway down a ladder most displacement never touches. They are also not harmless paperwork. A one-point rise in a county's filing rate predicts a measurable rise in sheltered homelessness the following year — an association that holds for filings even where judgments show none (Treglia, Byrne & Rai, 2023).

The Mark & the Move

The record marks people the courts never evicted. And the people it displaces, the data can barely follow.

The mark. Screening reports "recite any eviction action filed, regardless of whether it is still pending or who prevailed" (Kleysteuber, Yale Law Journal, 2007), and roughly 22% of eviction records carry ambiguous or false outcome information (Porton, Gromis & Desmond, 2021). Nine in ten landlords screen through an industry that grew from $1 billion to $4.5 billion between 2020 and 2024; the filing attaches its "Scarlet E" even when the case was dismissed (Benfer, 2025). The disparity data makes the mark's reach visible: Black renters face a 6.2% filing rate against a 3.4% judgment rate — the space between those numbers is a population marked by screens without ever being evicted by a court. Twenty states and D.C. have passed record-sealing laws in response.

The move. Court records end at the courtroom door: they "do not capture whether a tenant ultimately vacated the property" (Gromis et al., 2022). Following families afterward means linking records to address histories — and the best tools systematically miss the people most affected. Consumer-reference data can track moves nationwide (Phillips, 2020), but in King County it captures roughly 760,000 adults of the 2.2 million the Census sees, codes over 97% of households as white, and finds renters at 15% in a county that is 39% renter (Ramiller et al., 2024). Doubling up and homelessness — the destinations that matter most — are largely invisible to every address-based method. Qualitative work fills part of the gap: displaced families move reactively, fast, into whatever will take them (DeLuca & Rosen, 2022). ERN's current panel work links filings to consumer address histories to map post-eviction destinations, with those biases stated rather than smoothed.

The health frontier. The newest work follows the harm itself. An NIH-funded team led by Daphne Hernandez (UTHealth Houston), with ERN as co-investigator, is comparing tenant health under strong versus weak local eviction moratoria (HOPE-M) and studying "invisible evictions" — tenants never evicted but pressured out by their landlords. Its first published study, surveying 1,085 tenants in Harris and Travis Counties drawn from court filings and at-risk households with no filing, finds that homelessness, economic hardship, and substandard housing each predict elevated risk of intimate-partner violence (Zapata et al., 2025). In King County, ERN-affiliated work finds unhoused adults with a prior eviction fare measurably worse on general health and substance-use disorder than unhoused adults without one (Kahveci et al., 2026).

Inside Displacement

Eviction is one instrument of displacement. Neighborhood change plays the others.

ERN distinguishes hard displacement — a formal, involuntary event, proxied by eviction filings — from soft displacement: the market pressure of rising rents and neighborhood change that pushes low-income households out with no legal event at all. The two substitute for each other. Where tenant protections are strong, formal filings are suppressed while displacement reroutes through non-renewals, buyouts, and owner move-ins — San Francisco's pattern. Where protections are minimal and market pressure low, eviction operates as the primary displacement mechanism — the pattern across much of the South.

This is the problem the Housing Precarity Risk Model exists to solve. Its eviction sub-model (EER) measures a neighborhood's filing rate relative to its own state's average and models it nationally — the standardization raw counts cannot give — while its displacement sub-model (EDR) estimates the net out-migration of low-income renters that filings never see. One model result belongs on this page: among the EER's 184 predictors, two time-to-evict variables — the notice period and the post-judgment window — rank in the top five. The speed of a state's legal process shapes its filing rate independent of its housing market: fast, cheap process invites filing; slow process deters it. The clock in Part I is not just a tenant's survival window — it is a cause of the counts themselves.

Who Builds the Data

No federal agency counts evictions. A network of researchers, courts, and advocates is building the count themselves.

Everything above depends on data nobody is required to collect. ERN's contribution is a method: a pipeline that mines scanned court records with natural-language processing, geocodes them, and estimates the demographics the records omit — built in Washington, documented for any jurisdiction, and offered as the backbone of a national collection strategy (Thomas, Ramiller, Ren & Toomet, Cityscape, 2024): "continuing the practice of collecting structured data where available and then gathering court records for text mining in regions with lesser-known trends... a comprehensive database now seems like a realistic goal."

The field is bigger than any one team — and the breadth is the point. As of July 2026, all of these are live:

National infrastructure. The Legal Services Corporation's Civil Court Data Initiative tracks eviction filings across 1,250 counties in 30 states, updated continuously. New America's Eviction Data Response Network (launched October 2024) funds and coordinates state data systems — its 2026–28 cohort spans eleven states and 26 million renters: Colorado, Delaware, Georgia, Indiana, Maryland, New Jersey, New Mexico, New York, Oklahoma, Pennsylvania, and Washington. Princeton's Eviction Lab publishes national filing counts and city-level tracking. Stanford's Legal Design Lab maintains a catalog of the whole landscape.

Statewide. Portland State University's Evicted in Oregon (led by Lisa Bates): filings, notice causes, representation, and outcomes for the whole state. The RVA Eviction Lab at VCU for Virginia. The Housing Alliance of Pennsylvania (115,619 filings statewide in 2024). The Massachusetts Housing Partnership's Housing Stability Monitor. CTData with the Connecticut Fair Housing Center. HOME Line's monthly Minnesota updates. Open Justice Oklahoma.

Metro and local. The Atlanta Regional Commission's eviction tracker (with Georgia Tech, the Atlanta Fed, and Neighborhood Nexus) and Georgia Tech's Southeastern Evictions Data Collective. January Advisors' daily Harris County dashboard. The Right to Counsel NYC Coalition's crisis monitors (with JustFix and the OCA Data Collective). The Anti-Eviction Mapping Project. Case Western's weekly Cleveland scrape, Milwaukee's parcel-level tracker, Michigan's Poverty Solutions study, Chicago's Law Center for Better Housing archive, and Georgetown's Civil Justice Data Commons for secure researcher access.

Each exists because the official count didn't. Together they are the closest thing the country has to eviction statistics — and the reason a national strategy, stitched from structured data where it exists and text-mined records where it doesn't, is now realistic rather than utopian.

The Difference

We don't just count evictions. We build the instrument that measures where they fall.

Most of what you have just read rests on data that does not collect itself. Eviction records arrive as a mess — sealed in one state, address-free in another, sitting as scanned images in a third. The Eviction Research Network exists to turn that mess into something a researcher, an agency, or an advocate can actually use, and to do it the same way in every state so the numbers can be compared.

A research center

  • One institution, one editorial voice
  • Publishes for a public audience
  • Leads with a headline number
  • Flagship product: a dataset

ERN — a research network

  • A confederation of researchers, agencies & legal partners
  • Publishes with the people doing the work
  • Leads with a method you can reproduce
  • Flagship products: the pipeline, the risk model, the network
ERN is housed in UC Berkeley's Department of Sociology; its applied arm, CiDR Lab, delivers the same methods under contract to governments, courts, and nonprofits.

Three things make ERN's reading of eviction different in practice:

  1. 1

    We measure where the record runs out

    The Housing Precarity Risk Model forecasts eviction and displacement risk down to the neighborhood — including places with no usable court data at all. Where records are sparse, the model fills them in; where they are dense, it ranks severity.

  2. 2

    One method, every state

    Court records → census tract → demographic estimate, by Bayesian inference on surname and neighborhood. Race is never assigned to a person, only estimated as a group rate. The same pipeline runs in every state, so a profile in Oregon is comparable to one in Maryland.

    Read the methodology →
  3. 3

    Displacement, not just eviction

    Eviction is the entry point; the real subject is where housing, health, criminal-justice contact, and climate exposure intersect. We study the whole displacement system, and we publish the code and citations so the work can be checked and reused.

    See the research →
The goal of all of it is the same: build things about eviction that can't be unseen — and that hold up when someone checks the math.

This primer is a synthesis for the public and the press. It is not legal advice. If you are facing eviction, contact a local legal-aid provider as early as possible — outcomes improve sharply with representation, and the timelines above leave little room to wait.
