  4. population
  5. age dependency ratio
  1. a the study of populations, especially their patterns in space and time
  2. b the number of individuals or proportion of the population in each age clas
  3. c a group of individuals of the same species living in the same area or interbreeding and sharing genetic information
  4. d genetically determined maximum possible age to which an individual of a species can live
  5. e the ratio of dependent-age people (those unable to work) to working-age people; it is customary to define workin-age people as those aged 15-65

5 Multiple choice questions

  1. the maximum number of human beings which can live on Earth at the same time; is dependent on the quality of life people desire and are willing to accept
  2. The pattern of change in birth and death rates as a country is transformed from undeveloped to developed. THere are three stages: (1) in an undeveloped country, birth and death rates are high and the growth rate is low; (2) the death rate decreases, but the birth rate remains high and the growth rate is high; (3) the birth rate drops toward the death rate and the growth and the growth rate therefore also decreases
  3. the continued growth of a population that occurrs after achievement of replacement level fertility is reached
  4. a disease that appears occasionally in the population, affects a large percentage of it, and declines or almost disappears for a while only to reappear later
  5. structure of a population divided into groups by age. Sometimes the groups represent the actual number of each age in the population; sometimes the group represents the percentage or proportion of the population of each age

5 True/False questions

  1. optimal carrying capacitythe maximum abundance of a population or species that can exist in an ecosystem without degrading the ability of the ecosystem to maintain: (1) that population of species; (2) all necesary ecosystem processes; (3) the other species found in that ecosystem


  2. speciesa group of individuals capable of interbreeding and producing fertile offspring


  3. birth rateThe rate at which deaths occur in a population, measured either as the number of individuals dying per unit time or as the percentage of a population dying per unit time


  4. zero population growtha group of individuals of the same species living in the same area or interbreeding and sharing genetic information


  5. human demographythe study of human population characteristics, such as age structure, demographic transition, total fertility, human population and environmental relationships, death-rate factors, and standard of living
