Scientific study of population characteristics (age, sex, life expectancy, birth rate, etc.)

Map that displays the size of countries based on population not land area

Average number of children a woman will have during her child bearing years (15-49)

Total number of live births per 1000 people in a population

Total number of deaths per 1000 people in a population

The annual number of deaths of infants, less than one year of age, compared with total live births.

The percentage by which a population grows in a year. (CBR-CDR ) /10 = NIR

The number of years an infant is expected to live

Measured by the rate of increase (as a whole number not a percentage divided by 70) The number of years it should take for a country's population to become twice its original size

Shows the movement from high births and high deaths to low births and deaths as countries economically and socially develop from LDCs to MDCs

Created a population explosion in Europe and North America and communities became healthier lowering death rates but still having many children for labor

Occurred in the 1950's when things like immunizations and sanitation of Europe and N America (Core) reached the peripheral areas of Africa, Asia, and Latin America lowering death rates and increasing population growth.

Any government system that provides monetary assistance to people with an inadequate or no income, usually retirees

Strategies used by governments to discourage childbirth, found in countries with large growing populations
