To determine the factor that most likely accounts for Nigeria's high population growth rate, we need to analyze the demographic information provided in the chart.
1. Population Growth Rate:
- Russia: -0.02%
- Brazil: 0.83%
- Nigeria: 2.54%
We can observe that Nigeria has the highest population growth rate of 2.54%.
2. Fertility Rate:
- Russia: 1.61
- Brazil: 1.81
- Nigeria: 5.31
The fertility rate represents the average number of children a woman would have during her lifetime. Nigeria's fertility rate of 5.31 is significantly higher than Russia's 1.61 and Brazil's 1.81.
3. Life Expectancy:
- Russia: 70 years
- Brazil: 73 years
- Nigeria: 52 years
Life expectancy indicates the average number of years a person is expected to live. Despite having the lowest life expectancy at 52 years, Nigeria still experiences the highest population growth rate.
By considering these factors, we can infer that:
- The high population growth rate in Nigeria is unlikely to be due to life expectancy, because Nigeria has the lowest figure among the three countries.
- Low fertility rate is not applicable to Nigeria as its fertility rate is, in fact, very high.
- High life expectancy doesn't apply either, because, once again, Nigeria's life expectancy is the lowest.
The most plausible factor contributing to Nigeria's high population growth rate is the high fertility rate of 5.31. This means that on average, women in Nigeria are having a significantly higher number of children compared to women in Russia or Brazil.
Thus, the factor most likely accounting for Nigeria's high population growth rate is the high fertility rate.
