Map Highlight: Public Use Microdata Areas (PUMAs)

From economic development to real estate market trends, Public Use Microdata Areas (PUMAs) provide analysts, businesses, and government agencies with a way to break down complex census data into actionable insights. 

What are PUMAs?

PUMAs are geographic units used by the U.S. Census Bureau to organize and analyze microdata from the decennial census and the American Community Survey (ACS). 

These areas partition each state, the District of Columbia, Puerto Rico, and Guam into areas with a minimum population of 100,000. The boundaries are redrawn every 10 years based on census data.

Acres’ PUMAs data is derived from the United States Census Bureau. 

Applications of PUMAs

PUMAs collect national and regional datasets which may be made publicly available through Public Use Microdata Sample (PUMS) files, providing critical insights for:

• Urban Planning: Identify housing trends, income distribution, and migration patterns.
• Economic Development: Support site selection and market research with demographic data.
• Real estate analysis: Understand population shifts and market demand.
• Funding Allocation: Federal and state agencies use PUMA data to guide investment in education, transportation, and healthcare services.

Although PUMAs do not directly impact individual landowners, they play a role in broader economic and policy decisions that can influence land values over time.
