Migration, Demographic Transition, and Population Control
There are many important demographic concepts to understand when studying how population and society work. Migration, demographic transition, and population control are three of many concepts which play a key role in understanding these ideas. Below are the definitions of these concepts and applications of each around the world.
“Migration is defined as any permanent change in residence. It involves the ‘detachment from the organization of actives at one place and the movement of the total round of activities to another’” (Weeks 264). Many things can determine migration and why people migrate to where they do. One important theory of migration, called the push-pull theory, describes such an idea. The push-pull theory says that some people move because they are pushed out of their former location, whereas others move because they have been pulled, or attracted, to another location. One example of this would be the potato famine that occurred in Ireland during the late 1840s. The Great Famine was a period of mass starvation, disease and emigration in Ireland between 1845 and 1852 during which the island's population dropped by 20 to 25 percent. Approximately one million people died and a million more emigrated from Ireland. The lack of food pushed the people to migrate to new locations where there was a pull of available food sources. There is always a reason for migration and a pattern of migration that is important in understanding population and society. Migration explains for the changes in population as well as the needs or desires of the people. It is an important demographic concept because these ideas are important in the overall wellbeing of a county and its continuation on into the future.
“Demographic transition is the process whereby a country moves from high birth and high death rates to low birth and low death rates with an interstitial spurt in population growth,...
