Source: L.A. FANS waves 1 and 2, Census 2000, and ACS 2005–2009. The items used to construct the socioeconomic disadvantage index (percent female headed household, percent of adults with less than high school education, and percent of adults in poverty) are based are average values of the estimates for the 975 individuals in the sample, who lived in 547 census-tracts. These individual estimates, described on page 6, are based on 2000 Census and 2005–2009 ACS data. Collective efficacy, the neighborhood safety variables, and mean census-tract BMI are based on aggregate responses drawn from the first wave of L.A. FANS, based on 65 census-tracts. Census-tract racial and ethnic composition is based on 2000 Census data alone, based on 65 census-tracts.
