This study compared risky sexual behavior (RSB) between migrant and non-migrant Nigerian men, and investigated the individual and community factors of RSB between the two groups. Data for the study were from the 2012 National HIV/AIDS and Reproductive Health Survey in Nigeria. It comprised 15,346 male respondents aged 15 to 64 years and made up of 7,158 non-migrants and 8,188 migrants. The data were analyzed using descriptive statistics, chi-square test, and multilevel binary logistic regression. More non-migrants (37.69%) than migrants (28.43%) were engaged in RSB.
