1.1 THE BACKGROUND OF THE STUDY
The consequences of population growth on the economic development of less developed countries are not the same because the condition prevailing in these countries are quite different from those of
developed economy. Therefore the body of literature on population growth in Nigeria has always emphasized either the negative or the positive effect.
Therefore in every discussion, it is conventional to start with a definition of terms used in such discussion. However, population growth can be seen by a demographer as a change in the size of the
population. But when this change occurs in such a way that it reduces the size of population, the demographer refers it as a negative growth but when it adds to the size of the population he regards it as a positive one. What we get from this concept is that population growth can be positive or negative depending on whether there is an increase or decrease in the size of a given population. Population whether positive or negative is derived from three demographic variables such as birth, death and migration rates
Udabah (1999) Threw more light on this by adding that birth and death rates in underdeveloped countries are quite different from that of developed countries. Births rate in underdeveloped are generally high, why those of developed countries are low. On the other hand, death rates are higher in underdeveloped nations. The higher rate of population growth is therefore a major characteristic of underdeveloped nations and is partly responsible for the low rates of economic development.
Moreover, the population of any country constitutes the most vital component of its resource base. This aspect is based mostly on its size, growth rate, spatial distribution, demographic structure and quality in
terms of level of education, fitness and social welfare. Population statistics are indispensable impute into the planning process in any area. To government issuing programmes for instance in the efforts of
government in the developing countries to feed the people and also
