Get Your Bearings on Small Census Geographies

Description

In this session, we’ll take a closer look at what the Census Bureau considers “small” geography. We’ll talk about the differences between 1-year and 5-year data, including the population thresholds that determine when data are available for smaller areas. We’ll also explain why some geographies appear in the 10-year Census but not in the American Community Survey. The target geographies for this session will include Block, Block Group, Tract, ZCTA (ZIP Code Tabulation Area), Place and County.
