There is minimal migration into these countries at this stage. Examples of countries that are in this stage are Least Economically Developed Countries in the modern world and Britain in the 18th century. The second stage is the transition whose main features are rapid population growth, declining mortality rates and increasing birth rates. This stage can be divided into early transition and late transition (Caldwell, 2010). In the early stages, birth rates are higher than the death rates and the population starts to rise progressively. This can be attributed to improved health care, hygiene, sanitation and food production and storage. Examples of countries in this stage are Nigeria, Bangladesh and Britain in the 19th century. In the late transition, the birth rate begins to fall steadily and the death rate continues to fall giving rise to a population increase. This is caused by improved standards of living, better status of women and improved mechanization. Migration into these countries increases slightly. Countries that are in this stage include Brazil, China and Britain the early 20th century. The final stage is the post- transition stage that distinguished by low mortality rates and low fertility rates resulting to minimal population growth. Examples of countries experiencing this stage include Brazil, China and Britain in the early 20th century (Caldwell, 2010). There is increased migration into these countries as they are fully development and endowed with economic opportunities. The three stages are explained in terms of urbanization, economic development and industrialization. The major weakness is that it lacks universal applicability since not all countries go through the three stages. Furthermore, some counties are yet to go through industrialization (Beard and Petitot, 2010). Trends in Fertility, Mortality, Migration and Urbanization in the U.S. During the Past Century The US is the third most populous country in the world and accounts for approximately 4.5 percent of the global population (Passel and Cohn, 2008). The population grew by over 205 million in the past century (Passel and Cohn, 2008). It is important to note that the population became increasingly diverse and older (Hunt, Hunt and Falk, 2008). These demographic changes have impacted on trends in present times and in future. The massive increase in population growth was due to an increase in the birth rate, a decrease in the birth rate and a rise in net immigration. It can be noted that the population was increasingly older in the 20th century. The population went through a profound demographic change as reflected in its aging population leading to an increase in the median age (Beard and Petitot, 2010). In addition to getting older, the population is became more ethnically and racially diverse. This was highly influenced by immigration which had a significant impact on the size and structure of the population. This shows that immigration on the rise throughout the century. In terms of fertility, there were fluctuations throughout the century. For instance, the fertility rates were highest in the ‘baby boom’ experienced in the 1950. However, sharp declines were recorded in the 1960s and 1970s (Beard and Petitot, 2010). The birth rates remained constant for the remaining period in the century.
