Steps We Followed
For the larger region (e.g., county, district, state), we inventoried the licensed or regulated full-time child care/early childhood education supply (including center and family child care, Head Start, and pre-kindergarten programs in public and private schools).
Using GIS, we mapped and geocoded the entire list of licensed or regulated providers for the region (only necessary if census tracts are to be used as proxies for neighborhoods).
