All Flashcards
Significance of TFR on population?
Influences age structure and overall population size.
Significance of IMR?
Critical indicator of a country's healthcare system and living conditions.
How to calculate population change?
(CBR - CDR) / 10 = % annual population growth rate.
Impact of emigration on population?
Decreases population size.
Impact of immigration on population?
Increases population size.
TFR trends worldwide?
Generally declining, higher in developing countries.
Define Total Fertility Rate (TFR).
Average number of children a woman has during her reproductive years.
Define Replacement Fertility Rate.
The number of children per woman needed to keep the population stable (around 2.1).
Define Infant Mortality Rate (IMR).
Number of deaths of infants under one year old per 1,000 live births.
Define Crude Birth Rate (CBR).
Number of births per 1,000 people in a year.
Define Crude Death Rate (CDR).
Number of deaths per 1,000 people in a year.
Define Emigration.
People leaving a country.
Define Immigration.
People entering a country.
What is the impact of TFR on population size?
Significantly influences age structure and overall population size.
Why is IMR a critical indicator?
Indicates a country's healthcare system and overall living conditions.
How do emigration and immigration affect population size?
Emigration decreases, immigration increases population size.
What factors influence fertility rates?
Education, healthcare, economic conditions, and cultural norms.
What is the trend of TFR worldwide?
Generally declining, but higher in developing countries.
What does replacement fertility rate indicate?
Population stability (no growth or decline without migration).
How is population growth rate calculated?
(CBR - CDR) / 10 = % annual population growth rate.
