The Gridded Environmental Impacts Frame (Gridded EIF) is an innovative, privacy-protected experimental dataset derived from the Census Bureau's confidential Environmental Impacts Frame (EIF) microdata. 

Organized on a fixed 0.01-degree grid, approximately 1.2 square kilometers in North America, the Gridded EIF provides detailed demographic counts by age, sex, race and ethnicity as well as counts of the population by race and ethnicity and household income decile. Additionally, the Gridded EIF makes available exposure data for several key environmental hazards, including air pollution, on the same grid.

By making this granular dataset accessible, we empower the research community to conduct advanced spatial analyses that yield deeper insights and surpass the capabilities of traditional aggregated place-based data studies, all while upholding the strictest confidentiality standards.

Additional annual Gridded EIF files for 2024 are now available. These include the same race-by-age-by-sex and race-by-income tabulations as previous releases, as well as a new dataset tabulating counts of housing units by age and income of householder and home value.
