NOTE: These tables should be used only for race/ethnicity comparisons, not for age, sex, or overall totals. This is because, if age or race/ethnicity was not specified, cases were prorated according to the distribution of cases for which these variables were specified. For the following years the states listed did not report age and/or race/ethnicity for most cases and were excluded: 1997 (CO, DE, DC, GA, MD, MI, MS, NJ, NY, OH, SC); 1998 (CO, DC, MI, NJ, NY, OH, SC); 1999 (CO, DC, MI, NJ, NY); 2000 (CO, DC, MI, NY); 2001 (CO, DC, MD, NJ, NY). Cases and population denominators have been excluded for these states/areas. Differences between total cases from this table and others in the report are due to different reporting forms and above listed exclusions. The 0 to 9 year age group is not shown because some of these may not be due to sexual transmission; however, they are included in the totals.
