Population dynamics

Any discussion of population dynamics tends to concentrate on population growth, usually considered as a scourge of sustainable development, and a thing that can be easily fixed by implementing mitigation measures. However, such an approach is simplistic as population dynamics is a complex and nuanced issue (Bloom n.d). Population dynamics not only involves the study of size and structural population changes in the long and short term, but also the ecological and biological process, which influence them. Population dynamics is also concerned with how the population is spatially distributed as well as its composition.Sample Healthcare Paper on Population dynamics

Factors affecting population dynamics

There are many factors, which affect the population dynamics of an area. First, there is the environmental factor, which has an influence on population dynamics (Hunter, 2000). The environment affects the population size because it puts a limit on the number of people who it can viably support. The environmental conditions will also affect the spatial distribution of people because people are attracted to environments, which are conducive for living. Areas with plenty of arable land tend to have higher populations as well as higher fecundity rates due to abundance of food. Urban environments also tend to attract more people who migrate there to search for opportunities, hence altering the urban centers’ population dynamics. The interactions between the population and the environment at an area are determined by the technology that is available, the culture of the population as well as any government policies that might be in place. The nature and extent of human activities affects the environment’s ability to sustain a given population.

Population dynamics is also determined by the life expectancy of a population as well as the fertility rate (Marchetti, Meyer, Ausubel 1996). When new migrants settle in an area, they alter the population dynamics of that area. Populations with net migration inflows will grow as more people are added to the population. Life expectancy is a function of modern progress, which has led to the improvement of diets as well as the quantity and quality of medical care available. These improvements have reduced the mortality rates considerably making people to live longer. The improved life expectancy has coincided with increased fecundity, especially in poor countries. This has led to an explosion in population growth, leading to the strain of natural resources.

Bremner et al. argue that there is a causal relationship between the population dynamics and the level of poverty within that area. This is because poor households on average tend to have more children compared to households that are more affluent. They speculate that this may be because poor communities generally have higher infant mortality rates compared to middle class families. Consequently, poor people may feel that there is a need to have more children to compensate for the likely loss of some of the children. In addition, poor women are unlikely to have information about family planning methods as well as the resources needed to procure those services. This leads to the increase in fecundity among the poor women.Sample Healthcare Paper on Population dynamics

Therefore, a number of factors, which work in concert, determine the population dynamics of an area. A combination of these factors in different magnitudes causes the uniqueness of the population dynamics observed in a given place.
