"The National Walkability Index is a nationwide geographic data resource that ranks block groups according to their relative walkability. The national dataset includes walkability scores for all block groups as well as the underlying attributes that are used to rank the block groups.

The National Walkability Index Methodology and User Guide (pdf) (2.63 MB, 2021) provides information on how to use the tool, as well as the methodology used to derive the index and ranked scores for its inputs. The index was developed using selected variables on density, diversity of land uses, and proximity to transit from the Smart Location Database.
