The Demographic Transition Model or Population Cycle

Demographic transition model or population recirculation phase 1 - high fertility rate and high mortality If the birth rate and mortality rate are high (about 35 people per 1,000 people), the natural growth rate is very low, there is little population increase, There is none. Due to the popularity of modern medicine and new agricultural technology, examples of the first phase of the population are rare today. In the Amazon forest there may be only a few tribes that are hardly connected to the outside world.

One way to observe changes in demographics is to use demographic transition models. The demographic transition model is based on observations of changes in birthrate, mortality, and demographic change in 1929 by American demographicist Warren Thompson. Walter Thompson has observed these changes in industrialized society over the past 200 years. According to the model, all countries have undergone the same transition or stage. Warren Thompson believes that the three main factors affecting the demographic model are the people's wealth, health care department, and education department. The wealth of Qatar is the result of oil discovery. Oil was discovered in 1940 and Qatar began importing in 1949 ("History of oil discovery"). Qatar 's economy depended on pearl diving and fishing before petroleum

In this article we will investigate the following questions. "Does the population change in Qatar follow the demographic transition model?" For this purpose, we observe the years of birth and birth of respondents, and by observing the years of daughters, mothers, grandmothers, and great-grandmothers , We collected questionnaires to see the number of children each woman lives each year. The number of children born and their children. Next, plot the resulting graph and analyze the data using Spearsman rank correlation. After analyzing the data, compare it with the various stages of the demographic model and compare it with various characteristics of each model such as birth rate and natural growth rate.

Using the two demographic characteristics - birth rate and mortality - the demographic transition model represents the gradual growth of the population at the economic development stage. Each stage is characterized by a specific relationship between birthrate and mortality. Stage 4. Low fertility rate, low mortality rate. Population growth is stable. The countries at this stage usually have a stronger economy, a higher level of education, a strong labor participation rate and a birth rate of about two children per woman.
