Blacks—In 2013, the overall rate among blacks in the United States was 1,147.2 cases per 100,000 population (Table 11B). The rate of reported cases of chlamydia among black women was 5.8 times the rate among white women (1,491.7 and 258.5 per 100,000 females, respectively) (Table 11B and Figure N). The chlamydia rate among black men was almost eight times the rate among white men (771.1 and 99.4 cases per 100,000 males, respectively).
Rates of reported cases of chlamydia were highest for blacks aged 15–19 and 20–24 years in 2013 (Table 11B). The chlamydia rate among black females aged 15–19 years was 6,907.6 cases per 100,000 females, which was five times the rate among white females in the same age group (1,383.3 per 100,000 females). The rate among black women aged 20–24 years was 4.1 times the rate among white women in the same age group (Table 11B).
Similar racial disparities in reported chlamydia rates exist among men. Among males aged 15–19 years, the rate among blacks was 9.5 times the rate among whites (Table 11B). The chlamydia rate among black men aged 20–24 years was 5.5 times the rate among white men of the same age group (3,282.5 and 594.0 cases per 100,000 males, respectively).
