Unit 2: Population and Migration Patterns and Processes (copy)

Rate of Natural Increase (RNI)

The annual percentage of population growth of a country for a one-year period, calculated as Birth Rate - Death Rate / 10%

Demographic Equation

Utilizes birth rates, death rates, immigration, and emigration statistics to demonstrate population growth.

Crude Birth Rate (CBR)

Annual statistic representing the number of live births per total population x 1,000.

Crude Death Rate (CDR)

Annual statistic indicating the number of deaths per total population x 1,000.

Total Fertility Rate (TFR)

Estimated average number of children born to each female of birthing age, calculated as Number of Children Born / Women Aged 15 to 45.

Dependency Ratio

Compares the number of people too young or too old to work with the number of people in the workforce.

Demographic Transition Model (DTM)

Theory explaining population changes over time, including migration, fertility, economic development, and urbanization.

Epidemiological Transition Model (ETM)

Accounts for population growth due to medical advances and predicts changes in population over time.

Zero Population Growth (ZPG)

Occurs when birth rates equal death rates, resulting in no population growth.

Population Pyramids

Graphical representation showing population structure, gender, and age distribution of a country or region.
