Population Terms

Demography - the study of population characteristics

Overpopulation- when the available resources cannot

support the number of people

Density - How many? The total number of people

Population Growth

0 AD 250 Million People 1803 AD 1 Billion People 1903 AD 1.6 Billion People 1950 AD 3.0 Billion People 1987 AD 5.0 Billion People 1998 AD 6.0 Billion People

Population Distribution

Population Concentrations

– East Asia– South Asia– South East Asia– Europe– North America

Sparsely Populated Regions

– dry lands– wet lands– high lands– cold lands

Population

Arithmetic Density: The total number of people divided by the total land area.

Physiological Density: The number of people per unit of area of arable land, which is land

suitable for agriculture.

Physiological Density: The number of people per unit of area of arable land, which is land

suitable for agriculture.

Agricultural Density: The number of farmers to the total amount of land suitable for agriculture.

Density

Arithmetic Density: The total number of people divided by the total land area.

Physiological Density: The number of people per unit of area of arable

land, which is land suitable for agriculture.

Agricultural Density: The number of farmers to the total amount of land suitable for agriculture.

Population

Crude Birth Rate : The total number of live births in a year for every 1,000 people alive in the society.

Crude Death Rate : The total number of deaths in a year for every 1,000 people alive in the society.

Natural Increase: The percentage growth of a population in a year, computed as the crude birth rate minus the crude death rate.

Population Characteristics

Crude Birth Rate : The total number of live births in a year for every 1,000 people

alive in the society. Crude Death Rate : The total number of

deaths in a year for every 1,000 people alive in the society.

Natural Increase: The percentage growth of a population in a year, computed as the crude birth rate minus the crude death

Population CharacteristicsFertility Rate: The average number of

children a woman will have throughout her childbearing years.

Doubling Time: The number of years needed to double a population,

assuming a constant rate of natural increase.

Infant Mortality Rate: - the number of deaths of children under the age of 1, per thousand of the general population.

Population Characteristics Life Expectancy : The average number of years

an individual can be expected to live, given current social, economic, and medical

conditions. Population under the age of 15 - usually shown

as a percentage of the total population of a country - dependency ages

Population over the age of 65 - usually shown as a percentage of the population. dependency age

Life Expectancy : The average number of years an individual can be expected to live, given current social, economic, and medical conditions.

Population under the age of 15 - usually shown as a percentage of the total population of a country - dependency age is 0-15

Population

Population Pyramids

Inverted bar graphs that show a wide population base (younger population) with a narrow top (older population).

Population Pyramids show:– Age Distributions– Dependency Ratios of under 15 and over 65– Sex Ratio - Male vs. Female

Developing Relatively Developed Developed (poor) (rich)

POPULATION & DEMOGRAPHICPYRAMIDS TRANSITION

Demographic Transition - Stage 1

Demographic Transition - the change in population characteristics of a country to reflect medical technology or economic and social development.

Crude Birth Rate: High 40-50 / 1,000 Crude Death Rate: High 40-50 / 1,000 Natural Increase Rate: None 0 / 1,000 Today, no country in the world is in Stage 1.

Demographic Transition

As medical technology is introduced, a population lives longer as the death rate is lower from the rates of stage one.

Crude Birth Rate: High 40+ / 1,000

Crude Death Rate: Lower 15 / 1,000 Natural Increase Rate: Very High 25+/1,000

As the wealth and education of a country increases, social norms, and use of contraception dictate the birth of fewer children per woman.

Crude Birth Rate: Lower 20 / 1,000 Crude Death Rate: Low 10 / 1,000 Natural Increase Rate: Low 10 / 1000

As the final stage in the transition of population characteristics, the fourth stage sees the population increase rate again at 0. This stage reflects a highly industrialized, educated society.

Crude Birth Rate: Low 10 / 1,000 Crude Death Rate: Low 10 / 1,000 Natural Increase Rate: None 0 / 1,000

Population

Solutions to Population Growth

Education Birth Control Socialization Abortion Sterilization Government mandate Population redistribution

Migration to resource rich areas Empowerment of Women $ for contraception & education Improving farming techniques in poor areas Sterilization Educating men w/ responsibility for birth

control Changing cultural norms to value girls

Addressing traditional religious values that may encourage gender preference and large families

Starvation Medical technology - costs of

maintaining vulnerable populations (old & young)

Disease Biological Warfare

Redistribution of wealth - improve standard of living for poor so that children aren’t as necessary

Addressing government policies to deal with their growing populations

Environmental pollution causing higher death rates
