Master Area Tract Identification, Latitude and Longitude Descriptive Array (MATILDA) Tract Extract Files from the 19th Census of Population and Housing

The Center for Demography and Ecology at the University of Wisconsin--Madison, obtained the MATILDA files from DUALabs to support ongoing research and analysis. This series contains geographic codes, area names, and total population and housing counts for states and counties; plus geographic codes, area names, total population and housing unit counts, and average latitude and longitude coordinates for census tracts in tract sequence and those place segments and minor civil division (MCD) or census county division (CCD) remainders and MCD's / CCD's without places lacking tracts.

The files contains records for states, counties, census tracts in tracted areas, and MCD (CCD) / place segments and MCD remainders outside tracted areas plus MCD's (or CCD's) outside tracted areas which lack places. This data comprises government records extracted from the Archival Research Catalog (ARC). See the ARC catalog entry for this series for more information on this data and how to order it.
