It appears that some errors occurred in applying the data from the national-level surveys to create values at geographic levels from block group through states. The producers of SimplyMap are reviewing the problem. Please verify data you use from the Health Care module with data from other sources.
The problem with the "Health Care" module appears to be limited to that specific module. Users may find some relevant health and diet variables available in the SimmonsLOCAL module as shown in the left column of this page.
