Transitions in the developing world have generally produced more rapid population growth rates in mid-transition than historically observed in the North. Two factors account for this very rapid expansion of population in these still largely traditional societies: the spread of medical technology such as immunization and antibiotics after World War II, which led to vastly rapid declines in death rates, and a lag in declines in birth rates. Nigeria is a country with the largest human population in Africa. Some of the results of human populations are; depletion of resources, human congestion, weather modification, high unemployment rate, environmental degradation and a lot more. It is stated in science that matter occupies space and space is limited, as a result, this phenomenon in turn will show that the fixed factor like space in the environment will be affected when a continuous factor like population growth is put on it.
Over the period of the demographic transition, declines in fertility and mortality cause important changes in a population 's age composition. In general, countries in the early stages of the transition have a younger age structure than countries in the later stages. A changing age distribution has significant social and economic consequences, e.g. for the allocation of education, healthcare and social security resources to the young and old. Assessments of this impact often rely on the so-called age-dependency ratio (DR) that summarizes key changes in the
