  18. 40. To estimate the number of years for a population to double, take the number 70 and divide it by the growth rate of the population.
  19. 41. based on averages; the number of years that someone is expected to live from a specific starting point; it changes as one grows older, and faces different risks.

  26. 49. The youth dependency ratio is a measure of the young dependents (age 0 – 14) in a population, people younger than the age of 15 in relation to the working–age population (15 - 64 years old) as a ratio.
Down
  1. 2. The total dependency ratio is a measure of both the young (age 0 – 14 years) and old dependents (age 65 and older) added together to show their number versus the independent population (15 - 64 year olds). The ratio is expressed as the total number of dependents (young and old) per hundred people in the workforce.

  6. 11. hypothesized that unchecked population growth would quickly exceed carrying capacity, leading to overpopulation and social problems (famine/war).
  7. 12. hypothesized that food production can & will increase to match the needs of the population; improved farming methods & new technologies enable this to happen.
