9. Doubling Time Write the formula for doubling time 70 / annual rate of increase (%)

10. Natural increase rate Write the formula for natural increase rate NIR = (CBR-CDR)/10

11. Crude Birth Rate Write the formula for crude birth rate What is the crude birth rate of Brazil whose population is 196.7 million and whose birth is 2.95 million? 15 CBR = (n/p) x 1000

12. Crude Death Rate Write the crude death rate formula CDR = (n/p) x 1000 What is the crude death rate of Brazil whose population is 196.7 million and whose death is 1.18 million? 6 Why are these 2 formulas important?

13. Calculation Example Write the formula for natural increase rate NIR = (CBR-CDR)/10 Brazil’s crude birth rate is 15. Its crude death rate is 6. What is its NIR?.9% What is its double time? 77 years

14. Ecological Footprint

15. – Per capita land requirement = per capita consumption (kg y -1 ) for food production (ha) mean food production per hectare of local arable land (kg ha -1 yr -1 ) -Per capita land requirement = per capita CO 2 emission (kg C yr -1 ) for absorbing waste CO 2 net carbon fixation per hectare of from fossil fuels (ha) local natural vegetation (kg C ha -1 yr -1 )

16. Human Social Factors to Population Factors

17. Indicators of Pop. Growth Write the factors that contribute to population growth – Age Distribution – Sex Distribution – Fertility rate – Economics – Politics – Social factors (culture)
