View High Resolution Version
This chart breaks down the number of new HIV infections among men who have sex with men in the U.S. in 2009 by race/ethnicity and age, showing: among white men who have sex with men, most new infections occurred among those aged 40-49 (3,400 new infections), followed by those aged 13-29 and 30-29 (3,200 each). 1,600 infections occurred among white men who have sex with men aged 50+. Among black men who have sex with men, most new infections occurred among those aged 13-29 (6,500), followed by those aged 30-39 (2,500), then those aged 40-49 (1,400). 450 new infections occurred among black men who have sex with men aged 50+. Among Hispanic men who have sex with men, most new infections occurred among those aged 13-29 (2,700), followed by those aged 30-39 (2,000) and those aged 40-49 (1,000). 300 new infections occurred among Hispanic men who have sex with men aged 50+. (Note: The estimate for each age range within a race/ethnicity group was calculated independently from the overall estimate for that group. Therefore, the sum of the estimates by age range may not equal CDC’s official incidence estimate for a race/ethnicity group.)

View High Resolution Version
This graph shows that in the US in 2009, an estimated 12,900 new HIV infections occurred among heterosexuals. 3,590 of those were among males and 8,800 among females. Among males by race/ethnicity, 2,400 were among blacks, 640 were among Hispanics and 550 were among whites. Among females by race/ethnicity, 5,400 were among blacks, 1,700 were among Hispanics and 1,700 were among whites.

Note that the total estimated numbers of HIV infections among heterosexuals includes an additional 510 infections. These represent cases among American Indians/Alaska Natives, Asians, Native Hawaiians/Other Pacific Islanders, and individuals of multiple races. Specific estimates of HIV incidence in each of these populations could not be reliably estimated due to the relatively small number of HIV infections.)
