DESIGN AND IMPLEMENTATION OF A COMPUTERIZED POPULATION CENSUS MONITORING SYSTEM A CASE STUDY OF NATIONAL POPULATION COMMISSION. A RESEARCH PROJECT MATERIAL ON COMPUTER SCIENCE
The purpose of the study was to design and implement a computer- based population monitoring system for Enugu State.
The researcher critically analyzed the existing census system to sort out the bottlenecks hindering the effective census computation. He went further to design the new system which is capable of solving the census problem within a twinkle of an eye using the computerized identity card.
Above all, he crowned his ability by writing a well tested program which is capable of calculating the zone, printing out the total of each local government area with the largest and the smallest population.
THE PROBLEM AND ITS SETTING
Population census is a total process of collecting, compiling and publishing demographic economic and social data pertaining at a special time, to all persons in a state or country (United Nation, 1958). It is essential to note that census does not mean just counting the number of people, but collecting a whole range of demographic economic and social statistics.
The census process may take three forms ie. The manual, the computerized and the semi-computerized process. The manual process is the movement of enumeration from house to house, street to street and even town to town counting people. The acquired data are summarized or summed up manually to give the actual census. The computerized process is just the issuing of identity card and computer numbers. Each card contains marital status, state of origin, ages sex, occupation etc. each time census is to be taken, the information on these cards are slotted into the computer and computed without moving from house to house.
The semi-computerized process is the combination of the manual and computerized process. Information is acquired manually by moving from house to house and data acquired is then added up using the computerized method. This method is recently employed by the National population census in Nigeria. This was used during the 1991 census.
