Extended Data Table 1 NYCHA development characteristics

From: Knowledge about others reduces one’s own sense of anonymity

  1. Demographic characteristics and pre-intervention outcomes for control (n = 30) and treatment (n = 39) developments. Randomization successfully balanced these variables across treatment and control (F(18, 50) = 1.45; P = .15 based on a two-tailed test; standard errors unclustered to provide a conservative estimate of balance). Development-level data is from 2017, with the exception of racial demographics (which are from 2016). Census block group level data is from ACS five-year rolling averages from 2012–2016. Crime and 311 call data are averaged across the three-year period prior to the intervention (November 2014 - October 2017).
