  1. DEMOGRAPHY: The study of human populations is called…

  2. WHY? • Identifying human needs: • Finding solutions: • Marketing Tools: • Globalization:

  3. Population is… “…a collection of persons alive at a specified point in time who meet certain criteria.” Not necessarily an entire country. i.e.

  4. Comings and Goings • There are only two ways to enter a population, by birth and by in-migration. • There are two ways to leave a population, by death and by out-migration. Therefore, three processes are relevant to demography: Fertility, Mortality, and Migration

  5. Industrialization has an impact… Given the impact of industrialization in the reduction of fertility and mortality and the international migration flows from less developed to more developed countries around the world… …it is a common practice among demographers to observe separately the demographic processes in less developed countries (also called developing countries) from those in more developed countries (also referred as developed countries).

  6. DEMOGRAPHERS LOOK AT ISSUES ACCORDING TO LEVEL OF DEVELOPMENT OF THE COUNTRY Less developed countries: • high levels of fertility. • high levels of infant mortality. • a high prevalence of HIV/AIDS. • high levels of out-migration to more developed countries. ______________________________________________ More developed countries: • low fertility patterns. • women having babies at later ages. • populations with below replacement levels of fertility. • and large numbers of migrants from less developed countries.

  7. Demography and Social Policy Interact. Social Policy: The One Child Policy in China • The sex ratio at birth is the number of males born per one hundred females born and is around 105 in most societies. • Since the 1980s in China it has been significantly • above 105. In the year 2000 it was near 120. • The rapid reduction of fertility in China along with the long-standing preference for sons have led to the selective abortion of female fetuses, and a sex ratio at birth above normal levels.
