Census Tract RUCA Codes, Version 1.11
The Census tract RUCA codes are only kept on the Department of Agriculture
Economic Research Service’s web site and the ZIP code version are only
kept on this web site. This assures that there is only one source of each
to eliminate the possibilities of update errors and timing lags.
