Health Clubs per Census Tract and More

The CGA developed summary data for a public health study investigating access to businesses that may impact obesity rates.

An ArcObjects procedure was developed to parse twenty categories of businesses by SIC codes from a nationwide business location file.

A second procedure counted the number of businesses by category for each Census Tract.

The resulting GIS database can be used for analysis and mapping.
