Population Case
The taking of census is not a modern phenomenon. Since the start of civilization, our ancestors had already determined the rationale of engaging in such tasks though inclined mainly for the purpose of taxation. Considering the characteristic of census being universality and simultaneity, various demographic measures are used as means in order to come up with concrete and certain results specifically pertaining to population growth and size. Size is indeed relative. It depends on how small or large a particular country is. Size is difficult to measure. It may increase, decrease or remains the same as affected by factors that are controllable and not.
Movements of population occur either within the borders of a country or outside their territories. Throughout the century, there has been a constant rural-to-urban migration usually motivated by economic or climatic reasons. The growing industry of job opportunities in the cities attracted unemployed farmers in the provinces in general which results to overcrowded urban areas. In addition, it appears that from early times peoples have exercised some measure of control over population. This is the result of the common notion among the people that overpopulation has tremendous effects on the country. However, despite the declining birth rates leading to declining growth in population, some believed that this is a more major problem at present than that of rapid population growth, thus resulting to a never-ending debate.
Since the time of the Black Plague, birth and fertility rates fallen so fast. In some parts of Asia, birth rates have been continuously declining even though there are no strict policies regarding birth-control programs and despite the fact that there are some generous incentives in order to promote procreation. If this continues, according to Michael Meyer, the country would be experiencing economic crises in most cases and the population will age quickly in one generation
