1 Motivating policy question

Policy question: How did the volume and geographic distribution of executed residential evictions in New York City change around the early implementation of the 2017 Right to Counsel law, the COVID-era eviction disruption, and the post-moratorium period?

This is a descriptive policy question, not a causal estimate. The NYC Open Data eviction file records executed evictions from 2017 onward, so the data cannot provide a long pre-policy baseline. It also does not contain tenant representation status, court filings, income eligibility, or the rollout status of each ZIP code. The analysis therefore asks whether the observed pattern of executed evictions is consistent with policy-relevant changes, not whether Right to Counsel alone caused those changes.

Component question 1: Did executed residential evictions decline after 2017, especially in the early Right to Counsel rollout period from 2018 to 2019, compared with the 2017 baseline?

Component question 2: Were changes in executed residential evictions geographically uneven across boroughs and Neighborhood Tabulation Areas (NTAs)?

Component question 3: How different is the post-moratorium pattern from the pre-pandemic pattern, and which boroughs appear to account for the largest observed rebound?

# Data source and scope

The dataset is the NYC Open Data Evictions file, downloaded as Evictions_20260430.csv. The public documentation describes the file as executed evictions within the five boroughs from 2017 to the present, compiled from New York City Marshals. Because the assignment focuses on housing policy, the analysis is restricted to residential records.

Right to Counsel was created in 2017 to provide free legal representation to eligible low-income tenants facing eviction. The program was initially designed as a phased rollout in high-eviction ZIP codes and was expanded citywide in March 2020, which overlaps with pandemic-era court disruption and the statewide eviction moratorium. That overlap is why the analysis separates 2018-2019 from 2020-2022.

3 Data quality checks

3.1 Check 1: Missingness

Variables with the most missing values
Variable Missing records Total records Missing share
Eviction Apartment Number 18,533 126,828 14.6%
Bin 11,756 126,828 9.3%

Community Board 11,316 126,828 8.9%
Council District 11,316 126,828 8.9%
Census Tract 11,316 126,828 8.9%

Ejectment 1,617 126,828 1.3%
Court Index Number 0 126,828 0.0%
Docket Number 0 126,828 0.0%

Decision: Missing apartment numbers are not corrected because the field is not necessary for the citywide, borough, or NTA-level analysis. Missing latitude, longitude, and NTA values are not imputed because assigning geography from partial address strings could introduce false precision. These rows are retained for time and borough analysis but excluded from NTA and map-based analysis.

3.2 Check 2: Duplicate records

Duplicate check
issue affected_rows action
Exact duplicate rows in standardized raw data 185 Removed with distinct() before analysis

Decision: Exact duplicate rows are removed. This is a conservative correction because rows that match across every field do not appear to represent separate executed evictions.

3.3 Check 3: Date validity and temporal coverage

Date validity and coverage check
invalid_or_unparsed_dates min_date max_date rows_before_2017 rows_in_partial_2026
0 2017-01-03 2026-04-24 0 5587

Decision: The 2026 records are kept in the cleaned data but excluded from annual trend comparisons because 2026 is only a partial year in this download. The analysis uses 2017-2025 for annual charts and uses monthly charts when showing data through 2026.

3.4 Check 4: Categorical consistency

Categorical values after standardization
Variable Value Records
Borough BRONX 39,976
Borough BROOKLYN 35,650

Eviction Legal Possession Eviction 1,786
Eviction Legal Possession Unspecified 1
Residential Commercial Residential 115,748
Residential Commercial Commercial 11,265

Decision: Abbreviated values were recoded into the full categories where the meaning was clear: R to Residential, C to Commercial, P to Possession, E to Eviction, and Y to Ejectment. Borough aliases were also standardized. Unspecified values were not dropped because they may represent real records with incomplete classification rather than invalid records.

3.5 Check 5: Spatial validity

Spatial data quality check
missing_latitude_or_longitude pct_missing_latitude_or_longitude outside_nyc_bounding_box missing_nta pct_missing_nta
11316 8.9% 0 11316 8.9%

Decision: Rows with missing or invalid coordinates are excluded only from spatial/NTA visualizations. They remain in non-spatial analyses because removing them from time-series totals would undercount executed evictions.

4 Univariate analysis

The univariate analysis focuses on variables directly tied to the policy question: execution date, borough, NTA, and execution type. These variables matter because Right to Counsel is intended to reduce the number of tenants who ultimately lose possession, and because the policy was rolled out geographically before becoming citywide.

4.1 Annual executed residential evictions

The pandemic years are excluded from the core RTC comparison because 2020-2022 reflect an extraordinary legal and administrative disruption rather than ordinary eviction enforcement. I keep those years visible elsewhere in the report, but I do not use them to assess the pre/post RTC pattern.

Interpretation: The annual distribution is relevant because it shows whether executed evictions fell after the law was passed and how sharply the pandemic period disrupted the series. A large drop in 2020-2022 should not be interpreted as Right to Counsel alone because it overlaps with court disruption and eviction moratorium policy.

4.2 Borough distribution

Executed residential evictions by borough, 2017-2025
borough evictions
BRONX 36317
BROOKLYN 31351
QUEENS 22019
MANHATTAN 16625
STATEN ISLAND 4106
Executed residential evictions by borough, 2017-2025
Borough Executed residential evictions
Bronx 36,317
Brooklyn 31,351
Queens 22,019
Manhattan 16,625
Staten Island 4,106

Interpretation: Borough is relevant because a citywide decline can hide uneven local effects. This chart is a count distribution, not a rate. A borough with more evictions may also have more renters, more housing court activity, or more concentrated rental distress.

4.3 Execution type

Eviction versus legal possession records
Execution type Records Share of records
Possession 108,735 98.5%
Eviction 1,682 1.5%
Unspecified 1 0.0%

Interpretation: This variable matters because the dataset includes both eviction and legal possession records. The policy question is about tenant displacement, but the administrative category can distinguish different kinds of executed warrants.

4.4 Highest-count NTAs

Top 15 NTAs by executed residential evictions, 2017-2025

Central Harlem North-Polo Grounds 2288
East New York 2267

Morrisania-Melrose 1501
Prospect Lefferts Gardens-Wingate 1459
Brownsville 1444
Washington Heights South 1394
Mott Haven-Port Morris 1252

Interpretation: NTA is relevant because Right to Counsel initially used geographic rollout logic. Concentration in specific NTAs suggests where housing instability was most visible in executed eviction records.

5 Multivariate analysis

The multivariate analysis examines how eviction counts vary jointly by time, borough, NTA, and policy period.

5.2 Average annual evictions by borough and period

Average annual executed residential evictions by borough and period
Borough Period Average annual evictions
Bronx 2017 baseline / law passed 7,392
Bronx Early RTC rollout / pre-COVID 6,355
Bronx COVID/moratorium disruption 679
Bronx Post-moratorium 4,726
Brooklyn 2017 baseline / law passed 5,895
Brooklyn Early RTC rollout / pre-COVID 5,294
Brooklyn COVID/moratorium disruption 832
Brooklyn Post-moratorium 4,124
Manhattan 2017 baseline / law passed 2,844
Manhattan Early RTC rollout / pre-COVID 2,502
Manhattan COVID/moratorium disruption 355
Manhattan Post-moratorium 2,571
Queens 2017 baseline / law passed 3,966
Queens Early RTC rollout / pre-COVID 3,702
Queens COVID/moratorium disruption 426
Queens Post-moratorium 3,124
Staten Island 2017 baseline / law passed 693
Staten Island Early RTC rollout / pre-COVID 628
Staten Island COVID/moratorium disruption 125
Staten Island Post-moratorium 593

Interpretation: This plot helps separate the 2018-2019 early rollout period from the 2020-2022 pandemic/moratorium period. If the early rollout average is lower than the 2017 baseline in multiple boroughs, that is consistent with a decline after Right to Counsel began. It still should not be treated as causal proof because other housing policies and economic conditions also changed.

5.3 NTA comparison: 2017 baseline versus 2018-2019 early rollout

Largest percentage declines among NTAs with at least 20 executed residential evictions in 2017
nta baseline_2017 early_rtc_2018_2019 absolute_change pct_change
College Point 55 22.5 -32.5 -59.1%
Stuyvesant Town-Cooper Village 20 8.5 -11.5 -57.5%
Ridgewood 134 73.0 -61.0 -45.5%
Middle Village 40 22.5 -17.5 -43.8%
Starrett City 76 43.0 -33.0 -43.4%
Glendale 50 29.0 -21.0 -42.0%
Kingsbridge Heights 197 115.5 -81.5 -41.4%
Prospect Heights 23 13.5 -9.5 -41.3%
Erasmus 181 112.0 -69.0 -38.1%
North Riverdale-Fieldston-Riverdale 48 31.0 -17.0 -35.4%

Interpretation: This relationship is useful because the early Right to Counsel period should matter most geographically if rollout intensity differed across places. NTAs below the dashed line had fewer average annual executed evictions in 2018-2019 than in 2017. That pattern is expected if access to counsel, tenant protections, or related housing policy reduced final executed evictions. It could also reflect broader citywide trends, landlord behavior, rent regulation changes, or other non-RTC factors.

5.4 Post-moratorium rebound by borough

Post-moratorium average compared with 2019 by borough
Borough 2019 evictions 2023 evictions 2024 evictions 2025 evictions Average, 2023-2025 Difference from 2019 Percent difference from 2019
Bronx 5,850 4,033 4,476 5,668 4,726 -1,124 -19.2%
Brooklyn 4,886 3,544 4,168 4,661 4,124 -762 -15.6%
Queens 3,350 1,733 3,475 4,163 3,124 -226 -6.8%
Manhattan 2,292 2,236 2,748 2,728 2,571 279 12.2%
Staten Island 597 522 658 600 593 -4 -0.6%

Interpretation: This table addresses whether the post-moratorium period returned to the pre-pandemic pattern. If some boroughs are near or above 2019 levels while others remain below, that would suggest the post-moratorium eviction landscape is geographically uneven rather than simply returning to the earlier citywide baseline.

7 Conclusion

The main descriptive finding from this structure should be stated carefully: executed residential evictions appear to change substantially across time and geography, but the dataset alone is not enough to isolate the causal effect of Right to Counsel. The most defensible interpretation is that the data can show where and when executed evictions declined, collapsed, or rebounded. To make a stronger causal claim, this analysis would need additional data on housing court filings, tenant eligibility, tenant representation, ZIP-code rollout timing, case outcomes, rental market conditions, and population or renter-household denominators.
