This technical brief describes the logical edits applied to the health insurance coverage items in the American Community Survey.  Beginning in 2009 the Census Bureau added a series of logical edits to the editing routine for health insurance coverage.  These logical edits, which were developed by the Census Bureau in conjunction with a Technical Advisory Committee, are intended to improve the reporting of the insurance coverage in the survey.   This brief provides an overview of the logical coverage edits, discusses the state-level impact on the estimated number of uninsured for 2008, and describes how to obtain ACS estimates and mircodata that incorporate the logical coverage edits.  December 2010.
