* MSAs were selected on the basis of the largest population in the 2010 U.S. Census.

† The variable used to identify county, which is used to classify cases into MSAs, was complete for ≤95% of cases in a state contributing data to this MSA. See Appendix A1.4 for more information.

NOTE: County was misclassified in the 2016 Alabama STD morbidity data resulting in inaccurate county-level case counts and rates. Tables will be updated when corrected data are available.
