In the United States, the rate of HIV infection is highest in blacks (44.3 cases per 100,000 population). The prevalence is also high among Hispanic persons (16.4 per 100,000 population). These increased rates are due to socioeconomic factors rather than genetic predisposition.

In the developed world, HIV infection is much more common in males. In 2015, males accounted for 81% of all diagnoses of HIV infection among adults and adolescents in the United States.

According to the most recent data, 70% of new HIV infections were reported in homosexual men, and infected heterosexual women outnumber infected heterosexual men nearly 2 to 1.

Men who have sex with men (MSM) are still much more likely to contract HIV infection than heterosexual individuals. despite sharp declines of infection among such populations in Western countries. The institution of preexposure prophylaxis in Western Europe, North America, and Australia has dramatically decreased transmission rates among gay men in those areas.
