time through births, deaths, and migration; and the determinants and consequences of such changes.

DEMOGRAPHY It

is an interdisciplinary field involving mathematics and statistics, biology, medicine, sociology, economics, history, geography, and anthropology. Its beginning often is dated from the publication in 1798 of An Essay on the Principle of Population by the British economist Thomas Robert Malthus.

DEMOGRAPHY Malthus

warned of the constant tendency for human population growth to outstrip food production and classified the various ways that such growth would, in consequence, be slowed. He distinguished between “positive checks” to population growth (such as war, famine, and disease) and “preventive checks” (celibacy and contraception).

EXAMPLE Mexico’s rapid population growth has severely strained government services, especially education and health care. This growing population has placed tremendous pressure on the government and economy to create new jobs.

EXAMPLE The economy has not been able to create enough jobs to keep up with population growth. Economic conditions have prompted thousands of skilled and unskilled workers to migrate north to the United States in search of employment.
