THE DEMOGRAPHIC TRANSITIONAL MODEL Chapter 2 – Key Issue 3

The Demographic Transition It is a model consisting of four stages that helps to explain the rising and falling of natural increase over time in a country. Historically, no country has ever reverted back to a previous stage. Thus, the model can be thought to have a beginning, middle, and an end.

The Four (Five?) Stages of DTM

The Demographic Transition Stage 1: Low Growth Marked by very high birth and death rates. No long-term natural increase No country presently is in Stage 1 Stage 2: High Growth Marked by rapidly declining death rates and very high birth rates High natural increase Europe and North America entered stage 2, as a result of the industrial revolution (~1750). Africa, Asia, and Latin America entered stage 2 around 1950, as a result of medical revolution-improved medical care.

The Demographic Transition Stage 3: Moderate Growth Marked by rapid decline in birth rates and steady decline in death rates Natural increase is moderate. Gap between CBR and CDR is narrower in stage 3 countries than stage 2 countries. Population grows, because CBR is still greater than CDR. Most European countries and North America transitioned to stage 3, during first half of twentieth century. Stage 4: Low Growth Marked by very low birth and death rates No long-term natural increase and possibly a decrease Country reaches stage 4 when population gains by CBR are diminished by losses because of CDR. Condition known as zero population growth (ZPG) Demographers more precisely define ZPG as the TFR that produces no population change. Population change results from immigration.

The Demographic Transition – Stage 5? Possible Stage 5: Decline Characterized by… Very low CBR Increasing CDR More elderly people than young persons Negative NIR Over time, few young women in child- bearing years Contributing to ever falling CBR Several European countries already have negative NIR. Russia is most notable hosting a negative NIR for 50 years.

The DTM

Declining Birth Rates Two Successful Strategies for Lowering Birth Rates Improving Education and Health Care Emphasizes improving local economic conditions so that increased wealth is allocated to education and health programs seeking to lower birth rates. Contraception More immediate results reaped than previous approach Met with greater resistance, because it goes against cultural or religious beliefs of some. Roman Catholics, fundamentalist Protestants, Muslims, and Hindus.

Declining Birth Rates

Religion & Babies – Hans Rosling

Thomas Malthus – Population In 1798 he published An Essay on the Principle of Population He claimed the population was growing faster than the increase in food supply. (Geometric and Arithmetic Growth) Malthus’s Critics Many geographers consider his beliefs too pessimistic. Malthus’s theory based on idea that world’s supply of resources is fixed rather than expanding. Many disagree that population increase is not a problem. Larger populations could stimulate economic growth, and therefore, production of more food. Theory and Reality Food production has increased over last 50 years faster than Malthus predicted. His model predicted world population to quadruple over the course of 50 years. Not even in India has population growth outpaced food production.

Population Resolution? One Child Policy What It Used To Mean There were lots of exemptions and only ~37% of the population was subject to the law. (Non-Han Exemption) 2007, 52.9% were permitted to have a second child if their first was a daughter; 9.6% of Chinese couples were permitted two children regardless of their gender. What It Means as of Nov 2013 One Child per Urban Family Two if a parent was an only child. Two Children per Rural Family Additional Exemptions What Are/Were the Implications? Demographers estimate that the policy averted at least 200 million births between 1979 and 2009. Gender disparity Poverty – Child Abandonment
