Source Compilation

The following is a comprehensive and complete list of sources used to compile database 

Use of Force Data Tables: This data consists of incidents by force category and subject injuries and was compiled primarily from Threat, Resistance and Injury (T.R.I.) Incident Worksheets and Investigative Supervisor's Assessment Reports (I.S.A.R.). Updated on a quarterly basis. Last updated in May 2020. Data used is compiled from 2016 4Q - 2020 1Q. ​


NYPD Arrest Data (Historic): This is a breakdown of every arrest effected in NYC by the NYPD from 10/21/2014 to 12/31/2017. This data is manually extracted every quarter and reviewed by the Office of Management Analysis and Planning. Each record represents an arrest effected in NYC by the NYPD and includes information about the type of crime, the location and time of enforcement. In addition, information related to suspect demographics is also included. This data can be used by the public to explore the nature of police enforcement activity. Last updated on May 5, 2020. (999.9K rows, 6 columns*)


NYPD Arrest Data (2019): This is a breakdown of every arrest effected in NYC from 1/1/2019 until 12/31/2020. (215K rows, 6 columns*)


NYPD Arrest Data (Year to Date): This is a breakdown of every arrest effected in NYC from 1/1/2020 until 3/31/2020. (44.8K rows, 18 columns*​)


Population FactFinder: New York City Population FactFinder (NYC PFF) provides detailed population and housing profiles for user defined areas within New York City. Using data from decennial censuses and the American Community Survey, the profiles are comprehensive, covering the most basic population statistics, along with detailed social, economic, and housing information. 

  • FactFinder Sources: 

    • Decennial Census: The decennial census provides the most accurate and detailed understanding about the count and distribution of the U.S. population. It is also important to note that, to ensure census participant confidentiality, data are never published below the block-level. Updated on FactFinder November 2017.

    • American Community Survey (ACS): The ACS is the most extensive nationwide survey currently available. From its annual releases, we are able to examine the city’s detailed demographic, social, economic, and housing characteristics. Each month, questionnaires are sent to a sample of approximately 300,000 addresses across the country, so households are continuously receiving and responding to the ACS. In order to have a large enough sample from which to create estimates of characteristics for small areas, the ACS “rolls-up” the sample for five-year periods. New York City Population FactFinder (PFF) relies on these five-year period estimates to produce all of its ACS profile content. Because these estimates span a five-year period, they are represented with a start-year and end-year (for example, 2014-2018). These do not represent change over that five-year period, but rather something akin to a five-year average. It is also important to note that ACS estimates are derived from a survey and are subject to sampling error. Consequently, all ACS estimates are published with Margins of Error (MOEs) at a 90% confidence interval. These MOEs are available in PFF in data reliability views. ACS data in PFF are available at census tract-, Neighborhood Tabulation Area-, and Public Use Microdata Area-levels. Last updated in FactFinder February 2020.
