The human population is also termed as demography. It is a discipline that has intellectual origins that date back to the 18th century. Demography is an interdisciplinary topic that draws insights from sociology, economics, medicine, statistics, anthropology, biology, and history.
The population might change as per the simple equation. The population at the end of a period is equal to the population as the beginning plus births and minus deaths during this period. The addition of births as well as the reduction by deaths might change a population.
The Factors Affecting the Human Population
The growth in the human population is decided by a birth rate, migration patterns, and death rates, and migration patterns such as emigration and immigration. For example, in the developed countries like America and Europe, the population growth happens at the rates of 0.1% annually and in developing countries, the growth rate in the population is more than 1.5% annually.
As stated by our Human Population assignment help tutors, in the developing countries, manual labour is considered the main labour and so the families have more children. If the pension is not good then people raise children so that they are looked after at an old age. In households, where women are educated and they participate in income, there is lesser number of children.
In places, where culture, tradition, and customers are highly respected, the population is higher as contraceptives are used very less.
Migration
The migration patterns should be analyzed carefully to determine the change in population. Urban growth has been massive. In the developing countries that have high population growth rates nearly the population is doubling within 10 years.
The population growth is the combined effect of natural increase and migration effects. A high increase might be offset by out-migration. The migration effects on the growth of population are much lesse compared to the effects of changes in mortality and fertility.
