The National Neighborhood Data Archive (NaNDA) is proud to announce we have updated our Social Services dataset for 1990-2021. In the past, NaNDA published versions of this dataset for years 2003-2017 at the 2010 Census Tract and ZIP Code Tabulation Area (ZCTA) geographic levels. This updated version underwent a rigorous data cleaning protocol, and has been published at four different geographic levels (2010 and 2020 Census Tract and ZCTA).  Be sure to download and read the detailed user guide to learn about the data cleaning process, and for advice on which geographic level to use.
