Geographic context can influence individual risk in populations disproportionately susceptible to HIV infection, such as transgender people. We examined factors associated with residing in Massachusetts cities with the highest HIV prevalence (geographic "hotspots") in a 2013 sample of 433 transgender adults who were not infected with HIV. Residing in hotspots was associated with older age, non-White race/ethnicity, low income, incarceration history, polydrug use, smoking, binge drinking, and condomless receptive anal sex during one's most recent sexual encounter with a partner who was assigned male sex at birth. Future research to understand the interpersonal and socio-structural factors that drive localized epidemics among transgender people is warranted.
