SAS dataset for Washington

The Public Use Microdata Sample (PUMS) file for Washington State Census 2000 data contain individual records of the characteristics for a 5 percent sample of people and housing units. The PUMS data are available for geographic units known as super-Public Use Microdata Areas (super-PUMAs) and Public Use Microdata Areas (PUMAs). Each super-PUMA contains a minimum population of 400,000 and each PUMA contains a minimum population threshold of 100,000.

In- and out-migration flow data and the characteristics of these migrants for states and sub-state areas can only be derived from the individual state 2000 Census Public Use Microdata Samples (PUMS). While in-migrants to any given state can be analyzed using that state's file, analysis of out-migration requires analyzing data from all 50 states, the District of Columbia, and Puerto Rico.
