In addition to the U. PUMA maps may be viewed in two ways. The maps appear in the form shown above. The second option provides the ability to view PUMAs in context with other geography, such as census tracts, and to display thematic pattern maps using the ACS data. The five-digit code is unique only to Arizona. The ACS year estimates were released in October The data are very fresh! The ACS year estimates will be released in the fall , and similarly on an annual basis — for the same PUMA geographic area definitions.
Soon we will have a time series. Then we will able to examine trends based on wide-ranging demographic-economic data for each or all of the vintage PUMAs. You are commenting using your WordPress.

One could always illustrate statistics via PUMAs, but these are not familiar to the public.
All About Public Use Microdata Areas (PUMAs)
They are the only sub-state geographic identifiers on the PUMS records. But now that these areas are being used to publish summary tables based on the American Community Survey data, they have become much more widely used. Because they are required to have a minimum population of ,, all PUMA areas exceed the 65, population threshold, thus insuring that there will be single-year ACS data for them published each year. Our purpose here is to describe these entities and refer you to resources that will help you to understand and use them.
