  1. aWe dropped facility-specific studies and their X–Y pairs in our analysis because these studies were too narrowly focused on the subset of a population data (e.g., bars, business places)
  2. bNon-violent and non-property crime studies are not included in this category because we could not categorize these types of crime (e.g., juvenile crime, calls for services, and non-categorized crime)
