CHAPTER ONE

THE PROBLEM AND ITS SETTING

INTRODUCTION

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.

        The emphasis on this study computerized population monitoring census system of Enugu state is on the semi-computerized and computerized process. The onset of technological revolution proved the need for employing scientific and technological device to most aspects of human activities.

        The absolute manual process of census computation practices in those days gave rise to unreliable, insufficient and approximate figures. This researcher’s belief is already given way to a more sufficient trusted mechanized process of collecting and computing satisfied data.
