Reports however, from the united nation show that the population at the urban centres has multiplied four times its initial growth since 1960 and would have risen to a projected number of about 5 billion in the year 2030. Report also has it that over 70 per cent of these populations would settle in cities and towns. Following independence, many administrative centres experienced major unplanned rapid urbanization .The ripple effect of these on cities being the core of urban development is enormous especially on the housing development which has eventually resulted in overcrowding, inadequate dwellings, deplorable urban environment, degrading public infrastructure, and to an extreme, “outright homelessness” (Adesoji David Jiboye, 2011) .
Nonetheless, According to Femi Olokesusi, 2011 quoting Onibokun et. al. (1987) and Onibolun and Kumuyi (1999), assert that various political and socio-economic factors have resulted in rapid growth of urban population resulting in informal settlements, poor housing and slums in Nigeria.

Since they must have shelter, all forms of informal procedures are adopted to provide housing.
