Slide 4

United States Census of Agriculture

  • Conducted every 5 years. Produces very detailed data at the U.S., state, and county (i.e., sub-state) levels.

  • Data for individual agricultural operations are protected from disclosure in published totals by using a threshold rule and a dominance rule

  • Primary suppressions result directly from these rules

  • Complementary suppressions are then determined to ensure primary suppressions may not be calculated from published data.
