Geographic Region: Public Use Microdata Areas (PUMAs)
Found out about PUMAs.
Public Use Microdata Areas (PUMAs) divide states into geographic areas containing no fewer than 100,000 and no more than 200,000 people and are defined specifically for the distribution of PUMS data from the decennial census, American Community Survey (ACS), and the Puerto Rico Community Survey. PUMS data are individual records about characteristics of people and housing stripped of personal identifying information. PUMAs allow data users to make statistical analysis and comparisons because these areas have almost identical population numbers.
