1. What is the crude birth rate (CBR) and how is it
calculated? Give an example of a country with a high CBR
and a low CBR.
- The crude birth rate (CBR) is the number of live births
per 1,000 population in a given year. It is calculated by
dividing the number of live births by the mid-year
population and multiplying by 1,000. For example, in 2020,
Niger had a CBR of 44.8 and Japan had a CBR of 7.3.
2. What is the crude death rate (CDR) and how is it
calculated? Give an example of a country with a high CDR
and a low CDR.
- The crude death rate (CDR) is the number of deaths per
1,000 population in a given year. It is calculated by
dividing the number of deaths by the mid-year population
and multiplying by 1,000. For example, in 2020, Bulgaria
had a CDR of 15.5 and Qatar had a CDR of 1.6.
