  • Household income levels
  • Age and education level of a population
  • Race and ethnic makeup of a community
  • How a population has changed over time

  • Data collected over a 60-month period
  • Available for:
  • Largest sample, most reliable, least current of all estimate periods
  • Best used when:
    • Accuracy is more important than having recent estimates
    • Analyzing very small populations

What is a PUMA?
There are five PUMAs (public use microdata areas) in Seattle. A PUMA is a decennial census area for which the U.S. Census Bureau provides specially selected extracts of raw data from a small sample (5-percent) of population and housing unit records. The data is from the American Community Survey and is screened to protect confidentiality. These extracts are referred to as ‘‘public use microdata sample’’ files. They allow you to create your own statistical tabulations and data summaries. PUMAs are delineated uniquely within each state and comprise areas that contain at least 100,000 people.
