This research was carried out to appraise the influence of fertility and migration on the age-sex population structure of Lagos State, Nigeria. Respondents were randomly selected and given questionnaire to fill with regards to fertility and migration trends in the study area. Using partial correlation and multiple regression analyses, we determined the influence of migration and fertility on the age structure of the population. The combined effects of the partial correlation of fertility and migration were 0.66 (males) and 0.79 (females). The regression analyses yielded influence of fertility of 9.6 and 11.7 for males and females respectively, which far outstrips the influence of migration of 6.4 and 1.5 for males and females respectively on the age-sex structure. Also, the base constant was –5.1 for females and –3.2 for males i.e. the minimum change in age of male and female populations that would occur before the influence of fertility and migration become noticeable. Finally, the socio-economic implications of the age-sex structure were highlighted.
