Exercise 2
The illustration below illustrates the evolution of the population age distribution and population dynamics in the Least Developed Countries (starting year: 2010), assuming that they adopt replacement level fertility rates.
1. Which is the largest age group 30 years after the fertility fall?
30-34 years.
2. In which year does CDR reach a minimum?
10 years after the reduction in fertility rates.
3. What is the (approximate) total population size 30 years after the fall?
~1,200,000,000
4. In which years do we observe a rise in CBR?
10,15, and 20 years after the fertility decline.
5. Does this population ever experience negative growth? When?
Yes, about 65 years after the fall.
