Demographic Transition Model

Demographic Transitions Model… is a series of line graphs that illustrate: how population changes over time… due to changing death rates… and changing birth rates… which in turn are affected by level of development or industrialization. The level of development of a country will determine certain conditions or services that affect both death rate and birth rate and consequently population growth.

Stage 1 – Pre-Modern Steady population Characterized by a balance between birth rates and death rates. Death rates and Birth rates are comparably HIGH. Underdeveloped country with poor education and services.

Stage 2 – Urbanization / Industrialization Characterized by a DECLINE in death rates. Birth rates rather steady at high rates or even rising. Rise in Population Occurs in lesser developed and developing nations There is enough health care and nutrition TO decrease death rates but birth rates are still high.

Stage 3 – Mature Industrial Death rates are stabilized. Birth rates start to decline. Rise in Population BUT Population moving towards stability. Occurs in developing countries and those that have recently become developed nations.

Stage 4 – Post Industrial Death rates are stabilized are lower levels. Birth rates are stabilized at lower levels. Stabilized Population. Population age structure is generally older. Developed nations such as Canada, Sweden, U.S etc.
