  2. 2. Outline Definition of human population growth What causes and what effects it Effects of population growth on the United States  Baby boomers Effects of population growth on Ghana
  3. 3. Definition Increase in the number of who inhabit a territory or state  http://dictionary.reference.com/browse/population+growth Population growth is the change in a population over time, and can be quantified as the change in the number of individuals of any species in a population using "per unit time" for measurement. In biology, the term population growth is likely to refer to any known organism, but this article deals mostly with the application of the term to human populations in demography.  http://en.wikipedia.org/wiki/Population_growth
  4. 4. Positive Population Growth Rate Increase in birth rate  Increase in fertility rate  Decrease in child mortality rate Decrease in death rate  Longer life-span
  5. 5. Reasons For Increase In PopulationGrowth Medical advances  Vaccinations, availability Better standard of living  Homes, clothing, food Advances in agricultural technology  Large scale farming More sanitation
  6. 6. How Far We Have Come http://www.youtube.com/watch?v=sc4HxPxNrZ0
  7. 7. United States About 2.1 births per a woman: fairly constant Life expectancy: increased  76.0 years in 1993  82.6 by 2050 Diversification by immigration Net immigration: 880,000 people per year
  8. 8. United States Population is increasing, but population growth rate is slowing down  Population to increase to 392 million by 2050  Growth rate to decrease from 1.1 in 1990 to .54 by 2040 Reason why growth rate is decreasing  Population is getting older  Increase in death rate
  9. 9. Expected Growth Immigration and fertility After 2011, each year the number of births should exceed the year before it 1/3 of the current population is caused by immigration
  10. 10. Baby Boomers During the Great Depression there was a decrease in birth rate When that generation reached adulthood, there was an increase in births 1957 had the most births ever recorded in history
  11. 11. Effects of Baby Boomers More focus on education (college enrollment) Marrying later, smaller families Economic issues
  12. 12. United States Increase in population is overall positive  More economic prosperity  More production of jobs  Better standard of living Downside of population growth  Economic instability in the future
  13. 13. Ghana Currently the growth rate is 2.9%  However it is not over populated In 1960, 12.3% of the population was immigrants In 2003  3% was over 65  43% was under 15
  14. 14. Ghana Children must enter the work force at younger ages to support large families Not enough funds for public education for that many children Repeated pregnancies causes health concerns
  15. 15. Population Policy Developed in 1969 3rd country in sub-Saharan Africa Meant to control the population growth  Structure the distribution of the growth
  16. 16. Expected Growth By 2015 the population is expected to be 26,359,00 By 2020 the population is to reach 35.2 million Current fertility rate: 5.5 children per woman  Is expected to increase Death rate is decreasing  Modern health care, more availabilty
  17. 17. Ghana Population growth is overall negative  Lower standard of living  Less education Economic instability- government welfare Health concerns  Child morbidity, death due to pregnancy, diseases
  18. 18. Work Cited http://users.rcn.com/jkimball.ma.ultranet/BiologyPag es/P/Populations.html http://www.census.gov/population/www/pop- profile/natproj.html http://www.iussp.org/Brazil2001/s30/S39_P10_Boadu. pdf http://www.nationsencyclopedia.com/Africa/Ghana- POPULATION.html
