Forces behind Population Change
Population change is affected by several factors positively and negatively in equal
measures. This ranges from natural or biological factors to manmade factors. Although the
magnitude of each factor varies widely depending on other factors related to the social and
economic setup of the population, a combination of these factors yield consistent trends in
different geographical regions. The forces behind population growth include; the mortality rate,
fertility rates, migration and the age structure (Wormald, 2015).
The last half-century has witnessed a sharp decline in fertility rates, and this is expected
to further decline in the near future. Global population is slowing due to the continued increase
in the declining fertility rates. Muslims, among other religious groups, have the highest fertility
rates as from 2010-2015. They have more children per woman. Between, 1950-1955 the average
woman was expected to have five children but as per 2015, the global average was about 2.5
children per woman globally (Wormald, 2015).
Life expectancy has been on the rise globally. Due to accessibility to healthcare, diet and hygiene
improvements, people across the globe are able to live a bit longer. Life expectancy is estimated
to have sharply increased by 2050 (Wormald, 2015). While estimating the evolving world
population, life expectancy is a key consideration. Differences in life expectancy globally also
contribute largely to the population growth. Jewish have the highest life expectancy amongst
other religious group...
