Human Population Growth

  1. 1. Report of Jamaica Olazo
  2. 2. “the power of population growth is greater than the power of Earth to produce subsistence.” Thomas Malthus ReportofJamaicaOlazo
  3. 3. BASIC CONCEPTS of Population Growth Biosphere all life on Earth Population: all members of a single species living in a given time and place and actually or potentially interbreeding.
  4. 4. Species: all individuals that are capable of interbreeding and is made up of populations. Ecosystem: all the interacting populations in a given time and place. Communities: all the organisms and their non- living environment in a defined area. BASIC CONCEPTS of Population Growth ReportofJamaicaOlazo
  5. 5. Sex Ratio and Age Distribution – together they tell how a population will grow. Sex Ratio – relative number of males and females in a population. Age Distribution – number of individuals of each age in a population. BASIC CONCEPTS of Population Growth ReportofJamaicaOlazo
  6. 6. DEMOGRAPHY – study of populations, their characteristics and changes.  study population size;  density and distribution;  age structure;  sex ratio;  Birth rate;  Death rate;  Immigration and emigration rates Demographers ReportofJamaicaOlazo

  10. 10. 1. Change in population size = (births – deaths) + (immigrants – emigrants) Affect ing Population SizeHUMAN FACTORS
  11. 11. POPULATION MOVEMENTS
  12. 12. POPULATION MOVEMENTS Migration – permanent change of residence of a person or group. Emigration – movement of people out of a country. Immigration – movement of people into a country. ReportofJamaicaOlazo
  13. 13. Push factors 1. No job opportunities; 2. Poverty; 3. War; and 4. Environmental disasters Circumstances in the country or origin that lead people to emigrate. Pull factors 1. Economic opportunity; 2. Political freedom; and (i.e. Democracy) 3. Better standards of living Conditions in the destination country that make emigration attractive. ReportofJamaicaOlazo
  14. 14. 1. Change in population size = (births – deaths) + (immigrants – emigrants) 2. (Crude) Birth rate - the number of individuals born during a specified time interval. Affect ing Population SizeHUMAN FACTORS Natural increase – when the birth rate is higher than the death rate, more people are being born than are dying so the population grows. ReportofJamaicaOlazo
  15. 15. 3. (Crude) Death rate - the number of individuals who die during a specified time interval. Affect ing Population SizeHUMAN FACTORS Natural decrease – when the death rate is higher than the birth rate. ReportofJamaicaOlazo
  16. 16. Demographic Transition Model - is an important factor in population growth.
  17. 17. 4. Total Fertility Rate (TFR) – the average number of children a woman has during her reproductive years. – Biotic potential: the maximum rate at which a population could increase when birth rate is maximal and death rate minimal. 5. Replacement Fertility - number of children needed to replace everyone in the population. Zero Population Growth: • birth rate = death rate.

  43. 43. THE WEALTH GAP AND POPULATION GROWTH CAUSE CONFLICT The stark contrast between affluent and poor societies causes social and environmental stress. * The richest 20% use 86% of the world’s resources * Leaves 14% of the resources for 80% of the world’s people to share * Tensions between “haves” and “have-not’s” are increasing ReportofJamaicaOlazo
  44. 44. Major Social Factor Determining Family Size is the ROLE OF WOMEN IN SOCIETY • Early marriages foster high fertility rates. • Lack of education opportunities for women reduces their options. • When level of education increases, fertility rates fall. • The most important factor is the ability of women to control the size of their family. • Access to birth control is key
