Overview

The LightBox Census Boundaries – Block Group API provides access to Census Block Group boundaries sourced from the U.S. Census Bureau. Block Groups are subdivisions of Census Tracts and contain collections of Census Blocks, providing a geographic level between tracts and blocks. They are commonly used to organize and analyze demographic, socioeconomic, population, and statistical information at a localized level. Through the API, developers and analysts can retrieve individual Block Groups by identifier, perform spatial queries, and incorporate Block Group boundaries into demographic analysis, market analysis, infrastructure planning, and other geospatial workflows.
