Cognability is a way to measure how well your neighborhood can support cognitive health (the ability to think, learn, and remember clearly) as you age. Neighborhoods with places to be physically active, socially engaged, and keep your mind active may boost brain health. However, not everyone has access to these places.

The COVID Neighborhood Project is a data collation effort whose aim is to collect and curate neighborhood-level COVID-19 case data from throughout the pandemic for all 50 states in the U.S. We work with state health departments to secure the COVID-19 data in accordance with all the necessary protections from the state health department.

Using the HMDA Longitudinal Dataset, this interactive map shows the geographic spread of originations at the metro-, county-, and Census tract-level throughout the United States in circles of various sizes.
