Many California residents live in areas that, based on demographic, socioeconomic and housing characteristics, may be hard to count in the 2020 Census. This interactive map* shows California census tracts and block groups shaded by their California Hard-to-Count Index, a metric that incorporates 14 variables correlated with an area being difficult to enumerate. Census tracts and block groups with higher CA-HTC indexes likely will pose significant challenges to numerate in 2020, while tracts and block groups with lower indexes should be easier to count.
