Demographic trap


According to the Encyclopedia of International Development, the term demographic trap is used by demographers "to describe the combination of high fertility (birth rates) and declining mortality (death rates) in developing countries, resulting in a period of high population growth rate (PGR)." High fertility combined with declining mortality happens when a developing country moves through the demographic transition of becoming developed.

During "stage 2" of the demographic transition, quality of health care improves and death rates fall, but birth rates still remain high, resulting in a period of high population growth. The term "demographic trap" is used by some demographers to describe a situation where stage 2 persists because "falling living standards reinforce the prevailing high fertility, which in turn reinforces the decline in living standards." This results in more poverty, where people rely on more children to provide them with economic security. Social scientist John Avery explains that this results because the high birth rates and low death rates "lead to population growth so rapid that the development that could have slowed population is impossible."

One of the significant outcomes of the "demographic trap" is explosive population growth. This is currently seen throughout Asia, Africa and Latin America, where death rates have dropped during the last half of the 20th century due to advanced health care. However, in subsequent decades most of those countries were unable to keep improving economic development to match their population's growth: by filling the education needs for more school age children; creating more jobs for the expanding workforce; and providing basic infrastructure and services, such as sewage, roads, bridges, water supplies, electricity, and stable food supplies.

A possible result of a country remaining trapped in stage 2 is its government may reach a state of "demographic fatigue," writes Donald Kaufman. In this condition, the government will lack financial resources to stabilize its population's growth and becomes unable to deal effectively with threats from natural disasters, such as hurricanes, floods, landslides, drought, and disease. According to Kaufman, many countries suffering from "demographic fatigue" will slip back into stage 1, resulting in both high fertility and high mortality rates. "If they do," he states, "these countries may soon reach zero population growth, but at a terrible price." He gives the example of Zimbabwe, where 26 percent of the adult population has AIDS and the average person has a life expectancy of only 40 years.
