Flow model of population
Population change, defined generally, is the difference in the size of a population between the end and the beginning of a given time period (usually one year). Specifically, it is the difference in population size on 1 January of two consecutive years.The change in total population over a period is equal to the number of births, minus the number of deaths, plus or minus the net amount of migration in a population. The number of births can be projected as the number of females at each relevant age multiplied by the assumed fertility rate.
Population get changed according to this framework
This paper argues that the systems approach provides the tools to both frame globalisation as well as provide guidelines for analysis. Globalisation is presented as comprising of five domains – political, economic, social, business and physical.
Young people today are coming of age in a world in which the process of economic and cultural integration is accelerating. Driven by an astounding rate of technological change, particularly in transportation, computerization, and telecommunications, globalization has radically reduced the need for spatial proximity between producers and consumers and consequently reshaped the organization, management, and production of industries and firms. Globalization has also been facilitated by a more favorable international political climate, the collapse of communism and increasing democratization, and financial deregulation that has allowed capital to become more mobile than ever before (Berry, Conkling, and Ray, 1997). Yet globalization has not been without its critics, who argue that while the economic benefits are potentially enormous, in some places it has resulted in new problems related to the clash of traditional and modern cultures, rising income inequality, and social polarization (see, for example, Milanovic, 2003; United Nations, 2004; Wade, 2004).
