Census has been a reliable exercise from time, from where government rely for decision-making, and aids for administration and planning. According to Robert M. Groves, (2010) Director of the United States Census Bureau;
“Just like we cannot survive without roads and bridges, the country does not function well without an updated census to distribute funds to areas that most need them and to support community decisions and their own future.”
The increasing complexity of modern life means a greater need to plan housing, schools, roads, transportation, and a vast range of social and economic requirement for nation. This cannot be done without a detailed count of the population. Census is being officially managed by some organizations or government, for example the National Population Commission (NPC).
The installation of computer in these organizations or bodies that manages census information will assist not only in fast-recording information but also in solving certain problems, which cannot be easily resolved manually. The human resource of any enterprises are considered to be their most valuable assets, if they are properly harnessed and are well motivated to perform their assigned tasks in such a manner as to enhance the enterprises goals and objectives.
Therefore, adequate population records will provide all the necessary information that is associated with people, which include the size of the population, age structure, educational attainment, labour force and socio-economic characteristics, unlike in the manual method which makes access to data and information very tedious. The integration of different databases so that these databases can be merged and processed together and mainly other reasons, prompted the researcher to develop software for this organization, National Population Commission (NPC).
1.1 Background of the study
Census taking in Nigeria can be traced to have started from as far back as 1966 after the colonization of Lagos by our colonial masters. Since then, there have been several attempts to count Nigeria population. However, these censuses are characterized by some difficulties and deliberate and ill-minded attempts to inflate population figures; just in favour of one geopolitical zone or the other. This does not and cannot represent the nation‟s image as regards to human population. As a result of this, the National Population Commission (NPC) was established using the Decree No. 23 of 1989. The brain behind this was to have successful censuses each time and as well accurate demographic data. It is no doubt that this Commission (NPC) was vested with a lot of powers and functions some of which are;
To undertake the periodic enumeration of the nation‟s population through census, sample surveys, etc.
To establish and maintain the machinery for continuous and universal registration of births and deaths
To collect, collate and publish data on migration statistics
To reach and monitor national population polity and set up national population information data bank.
Unfortunately, Nigeria still relies on foreign statistics population information data bank for most of their population estimation.
1.2 Statement of the problem
There are many problems affecting the National Population Commission from maintaining a steady reliable figures and estimates. These are the more reasons, why the researcher embarked on this research;
Ø inadequate manpower
Ø lack of equipments
Ø poor organisation
Ø unstable polity
Ø manual bulk carrying of data
1.3 Objectives of the Study
The objectives of this study are summarized as follows:
Ø To develop computerized software that automatically stores and retrieves all information on human population.
Ø To develop a reliable system that could be used in collecting data/information on human population.
Ø To develop a system that will support direct access to the specific and required information
1.4 Significant of the Project
Ø The system will solve problem associated with the acquisition, storage, and retrieval of information on human population with ease.
Ø A timely retrieval of information is anticipated with efficiency and reliability.
Ø It will provide security to data that are unauthorized, users will not gain access to those files and fraud will be minimized in the society which will lead to
improvement in administration processes.
1.5 Scope of the Project
The major aim of the project is to design a system that will have all information about human population and retrieving of data when ever needed in the society. It focuses on the registration, retrieval and management of information about individuals in the society.
1.6 Limitation of Study
During the course of this study, many things militated against its completion, some of which are;
Ø Lack of finance
Ø Refusal of the National Population Commission Awka, to give detailed answers and in some cases no answer at all to some questions
Ø This project is limited to all the data associated with census population figure gotten from the National Population Commission.
Ø Due to time factor, not all the commissions were reached for source of data and information.
1.7 Definition of terms

Ø MIGRATION: Migration is the act of moving from one region or country to another. It is the movement of a group of people, births, or other animals that
move in group from one region to another.
Ø ESTIMATION: Estimation is the act of making an approximate calculation of something.
