Chapter 2 Part 2

Front 1

Physiological Density

Back 1

A measure of population density that is found by dividing the total number of people by the area of AREABLE land.

Front 2

Population composition

Back 2

Aspects that make up a population. These can include sex, age, marital status, and education

Front 3

Population density

Back 3

A measure of total population relative to land size.

Front 4

Population distributions

Back 4

Descriptions of locations on the earth’s surface where individuals or groups live.

Front 5

Population explosion

Back 5

The rapid growth of the worlds human population during the past century, attended by evershorter doubling times and accelerating rates of increase.

Front 6

Population pyramid

Back 6

This is a visual representation of the composition of a population in terms of age and sex

Front 7

Rate of natural increase

Back 7

The difference between the number of birds in the number of deaths

Front 8

Restrictive population Policy

Back 8

A policy that is now generally enforced by the majority of the world’s government. This policy range from toleration and promotion of birth control to prohibition of large families. China’s “One Child Policy” is an example of this.

Front 9

Stage five

Back 9

This is a stage of the demographic transition characterized by a declining population. Birth rates continue to fall and drop below death rates. Death rates remain steadily low.

Front 10

Stage four

Back 10

This is a stage of the demographic transition characterized by a decrease in population growth. The birth rates continue to fall while the death rate remains steadily low.

Front 11

Stage one

Back 11

This is a stage of the demographic transition characterized by low population growth. There are high birth and death rates in this stage.

Front 12

Stage three

Back 12

This is a stage of the demographic transition characterized by a population explosion. Birth rates remain high although they begin to fall. Death rates are very low (still decreasing but close to leveling off)

Front 13

Stage two

Back 13

This is a stage of the demographic transition characterized by increased population growth. There are high birth rates and declining death rates.

Front 14

Stationary population level

Back 14

A term abbrev. SPL that refers to a theory that the global population will stop growing sometime during the 21st-century and reach this stage.

Front 15

Malthusian Theory

Back 15

Thomas Malthus believed that the worlds population was increasing faster than the food supply needed to sustain it. He thought that food supplies grew LINEARLY and that population grew EXPONENTIALLY.

Front 16

Total Fertility Rate

Back 16

Average number of children born to a woman during her lifetime. A (TFR) of 2.1 or higher indicates is the stable population.

Front 17

Zero Population Growth

Back 17

A state in which a population is maintained at a constant level because the number of deaths is exactly offset by the number of births.

Front 18

Ehrlich Theory

Back 18

Stanford university professor Paul Ehrlich predicted worldwide famine in the 1970s and 1980s due to overpopulation, and advocated immediate action to limit population growth. Fears of a “Population explosion” were widespread in the 1950s and 1960s, but the book in its author brought the idea to an even wider audience.

Front 19

Epidemiological Transition Model

Back 19

Process by which the pattern of mortality and disease is transformed from one of high mortality among infants and children in episodic famine and epidemic affecting all age groups to one of degenerative and man-made diseases (such as those attributed in smoking) affecting principally the elderly.
