Last week, the Census Bureau posted a new blog, ACS Updates on Disclosure Avoidance and Release Plans, that describes their efforts to strengthen disclosure avoidance methods by discontinuing certain ACS tables on final interview counts. The Census Bureau will continue to publish the quality measures tables that provide this information for select geographies. But they are discontinuing the tables that included this information for all geographies.These data were published in Tables B00001 and B00002 in the 1-year and 5-year ACS products as well as K200001 and K200002 in the 1-year supplemental ACS product.
You can find more information about this change on their website:
