World Population Balance

Population growth is one of the ways a sociologist can view the changes within society. A population consists of everything or everyone being studied in an inference procedure. Populations can be large in size, although this is not necessary. What is important is that a population includes all of what we are curious about. Populations consists of groups, which must be living in the same area at the same time (Taylor). The number of individuals that inhabit a place in society at one time is called size. The number of individuals in a specific area refers to the density. And lastly, the size of the population as it changes overtime is the growth population.

We know a population consists of groups of individuals in a particular area. The amount of people in area is determined by three main things. The amounts of live births, deaths, and natural changes: such as migration. The birth rate refers to the number of children which are born. The CIA Site Redirect states: the average annual number of births during a year per 1,000 persons in the population at midyear; also known as crude birth rate. The birth rate is usually the dominant factor in determining the rate of population growth. It depends on both the level of fertility and the age structure of the population (CIA Site Redirect, 2010).

As one would deduce, the number of deaths within a population can affects its growth. Death rate, which does not account for all categories of mortality in a population, it is a point at which to gauge the mortality situation in a country, accurately indicates the current mortality impact on population growth. The average annual number of deaths during a year per 1,000 population at midyear; also known as crude death rate (CIA, 2013).
