Changes can occur that adjust the original baseline counts, e.g., classification changes, area boundary changes, new areas designated nonattainment.
See the report listing these adjustments to original 2009 nonattainment areas.

County subtotals and grand totals may not equal sum of parts. Part counties are only counted one time within groups.
