**2. Nigeria demographics**

Demography is the study of the quantitative and qualitative aspects of human population. It shows the distribution of people across the continent, countries, and regions. The quantitative aspect of demography includes the population composition, density, distribution, growth and size while the qualitative aspect includes sociological in nature. These are factors such as education quality, diet and nutrition, race, social class, crime, wealth and wellbeing. Nigeria is the most populous country in Africa and also the most populous among the black nations of the world. Globally, Nigeria is among the 10 top countries with the largest population [5]. Most of this are people in the working ages, between age 15 and 64. The median age of the population is 22.7. **Table 1** shows Nigerian population growth from independence till date and the population projection till 2050. The growth in population have resultant impact on the population density. The table shows that the urban population also continues to increase in proportion to the population growth. This in no doubt compounds the problem of housing provision and shortage in the urban centers.

According to the national bureau of statistics [6]. Nigeria's population has consistently been on the rise. The NBS record shows Nigeria population as consisting more of younger population. By implication, there will be need for quality housing for this growing population in the future. This does not discountenance the acute shortage of quality and affordable housing currently bedeviling the country. The housing shortage in the country has also grown geometrically with the population while efforts to reduce the housing gap have not yielded commensurate results. Available data indicates that housing deficits has continued to grow in direct proportion to the population growth (**Table 2**).
