Does NASS Update the County Data in Later Years?
NASS has a policy of reviewing data the year after initial publication. Based on new administrative data, States may revise the previous year of county data. These changes are made at the same time the "current year" data are prepared. Following the Census of Agriculture, every five years, NASS reviews the data for intervening years and revises data when appropriate. Generally, revisions are small and a limited number of States and years are changed for any commodity.
