In order to assist in 2020 Census planning and operations, including Re-Engineered Address Canvassing and other activities, the Census Bureau created a tabulation block-based typology or classification scheme based on similarities in the types of residential units the block contains and the changes in the Census Bureau’s address list over time, with an emphasis on hard-to-canvass residential types added since 2010. The block typology denotes blocks containing zero population or housing or primarily single-family homes, large multi-unit apartment buildings, group quarters, or mobile homes. This presentation outlines the approach used by the Census Bureau’s Geography Division to classify blocks, using multiple address-level variables, and will include the logic and decision tree needed to classify all 11.1 million Tabulation Blocks. This classification may be useful to researchers of census data in addition to other types of classifications.
