Show the rate-of-natural-increase calculation before applying the rule of 70.
- 1.A country has a birth rate of 28 per 1,000 and a death rate of 8 per 1,000. Find its rate of natural increase as a percent.
- 2.Using that 2.0% rate, estimate doubling time with the rule of 70.
- 3.A population pyramid has a very wide base and a sharply narrowing top. What demographic transition stage does this likely suggest?
- 4.Name two changes commonly associated with a country moving into Stage 3 of the demographic transition.
