4. b. Exponential Growth (J-curve) a. Linear Growth

5. 1. China 2. India 3. United States 4. Indonesia

6.  Doubling Time = 70 / r (r is % population growth rate) Use the number in front of the % - DO NOT change it to a decimal!!!

7.  Doubling Time = 70 / r (r is % population growth rate)  Doubling Time = 70 / 2 = 35 years

8.  Doubling Time = 70 / r (r is % population growth rate)  Doubling Time = 70 / 2 = 35 years a) 2012 + 35 = 2047 (year that population will double from 50,000 to 100,000)

9.  Doubling Time = 70 / r (r is % population growth rate)  Doubling Time = 70 / 2 = 35 years a) 2012 + 35 = 2047 (year that population will double from 50,000 to 100,000) b) 2047 + 35 = 2082 (year that population will double from 100,000 to 200,000)

10.  Doubling Time = 70 / r (r is % population growth rate)  Population doubled from 12 million to 24 million in 20 years

11.  Doubling Time = 70 / r (r is % population growth rate)  Population doubled from 12 million to 24 million in 20 years  20 = 70 / r  r = 3.5%

14.  Average number of children born to women in a population during their reproductive years.  1.6 developed countries  2.8 developing countries

15. TFR = 3.7 1957

16.  Average number of children couples in a population must bear to replace themselves.  2.1 developed countries  2.5 developing countries

17.  # children per 1000 live births that die before age 1.  One of the best indicators of quality of life in a country.

18.  # live births per 1000 people in a population in a given year.

19.  # deaths per 1000 people in a population in a given year.

20. (S-curve) Carrying Capacity (K)

22.  Population Change = (immigration + births) – (emigration + deaths)

23.  Crude birth rate of 45:  45/1000 = 0.045 = 4.5%  Crude death rate of 20:  20/1000 = 0.020 = 2.0%

24.  Population Change = (immigration + births) – (emigration + deaths)  Population Change = (1% + 4.5%) – (0.5% + 2.0%) = 5.5% - 2.5% = 3.0%

25. Demographic Transition Model High birth High death High birth Declining death Declining birth Low death Low birth Low death Phase 4: Post-industrial Phase 3: Industrial
