US Block Groups Regional Geography Reference
As a reference for users, Motionworks provides this cross-reference to allow users to understand how data reported at the United States Census Block Groups may be aggregated to larger Census Regions.
📘 CBSA and MSA Geographies
CBSA or "Core Based Statistical Areas" refer collectively to BOTH the metropolitan (
us_metro) and micropolitan (us_micro) statistical areas with more than 10,000 population.MSA or "Metropolitan Statistical Areas" refer ONLY to the larger metropolitan (
us_metro) statistical areas with more than 50,000 population.
The universal geography_id and the associated regional geographic identifiers are used and can be referenced back to the core Geography Reference Datasets.
