What is Total Fertility Rate (TFR)?
Average number of children a woman has during her reproductive years.
What is Replacement Fertility Rate?
2.1 children per woman needed to keep population stable.
What is Infant Mortality Rate (IMR)?
Number of deaths of infants under one year old per 1,000 live births.
What is Crude Birth Rate (CBR)?
Number of births per 1,000 people in a year.
What is Crude Death Rate (CDR)?
Number of deaths per 1,000 people in a year.
What is Emigration?
People leaving a country.
What is Immigration?
People entering a country.
Effect of increased healthcare access on population?
Impacts infant mortality and lifespan.
Effect of education on TFR?
Especially for women, linked to lower TFRs.
Effect of economic conditions on family size?
Can influence family size decisions.
Why is IMR higher in developing countries?
Lack of contraceptives, inadequate sex education, limited access to medical tech.
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.
