We use an anonymized snapshot of all active Facebook users and their friendship networks to measure the intensity of connectedness between locations. The Social Connectedness Index (SCI) is a measure of the social connectedness between different geographies. Specifically, it measures the relative probability that two individuals across two locations are friends with each other on Facebook. Each entry represents a pair of locations, detailing the strength of social connectedness between them. By doing so, the SCI provides a measure of the relative probability that two individuals from different locations are Facebook friends, offering insights into social ties across regions. The dataset has a a size of 3,9 kB and reflects a specific snapshot in time, with the latest available data from October 2021. The dataset is organized into multiple sub-datasets, each detailing social connectedness at different geographic levels:​

  1. Country-Country Pairs:

    • user_loc: ISO2 code of the first country.​

    • fr_loc: ISO2 code of the second country.​

    • scaled_sci: Scaled Social Connectedness Index between the two countries.​

  2. US County-Country Pairs:

    • user_loc: 5-digit FIPS code of the U.S. county.​

    • fr_loc: ISO2 code of the country.​

    • scaled_sci: Scaled Social Connectedness Index between the U.S. county and the country.

This free download is a database of more than 12,000 civilian complaints filed against New York City police officers. After New York state repealed the statute that kept police disciplinary records secret, known as 50-a, ProPublica filed a records request with New York City’s Civilian Complaint Review Board, which investigates complaints by the public about NYPD officers. The board provided us with records about closed cases for every police officer still on the force as of late June 2020 who had at least one substantiated allegation against them. The records span decades, from September 1985 to January 2020. Each entry includes specifics such as the nature of the allegation (e.g., use of force, abuse of authority), the outcome of the investigation, and any disciplinary actions taken. The dataset provides information on the officers involved, including their rank and assignment at the time of the complaint. Entries contain timestamps and locations of the alleged incidents, facilitating analyses of patterns over time and across different areas.​​

Structurally, the dataset contains the following information: ​

  • Complaint ID: A unique identifier for each complaint.​

  • Date and Time: When the incident allegedly occurred.​

  • Location: Where the incident took place.​

  • Officer Details: Information about the officer(s) involved, such as badge number, rank, and assignment.​

  • Allegation Details: Type of misconduct reported (e.g., excessive force, discourtesy).​

  • Investigation Outcome: Findings of the investigation, including whether the allegation was substantiated, unsubstantiated, exonerated, or unfounded.​

  • Disciplinary Action: Any penalties or corrective actions imposed following the investigation.
