Human Population Growth
Human Population Growth Status of Our Species
Factors that Affect Human Population Size Birth RATE-(Natality) Number of individuals born per unit time Death RATE-(Mortality) Number of individuals that die per unit time Population Change =(Births + Immigration)-(Deaths +Emigration)
Population Change Doubling Times Rule of 70 Fertility Replacement Fertility Total Fertility Rate (TFR)
Factors Affecting Birth Rates Children in Labor Force Cost of Raising and Educating Children Generation Distance Availability of Pension Systems Urbanization Education and Employment of Women Infant Mortality Rate Average Age of Marriage Availability of Birth Control
