  1. Which country is growing the fastest?
  2. Which country is growing the slowest?
  3. Which factor most likely contributes to Brazil's population growth rate?
  4. Which factor most likely contributes to Nigeria's population growth rate?

Verified Answer :

  • Fastest growing country: \(\boxed{Nigeria}\).
  • Slowest growing country: \(\boxed{Russia}\).
  • Factor for Brazil's growth: \(\boxed{Low \ fertility \ rate \ (1.81)}\).
  • Factor for Nigeria's growth: \(\boxed{High \ fertility \ rate \ (5.31)}\).

Explanation

  1. Analyzing the Provided Demographic Data

The problem provides demographic indicators for Russia, Brazil, Nigeria, and the Global average. The indicators are the "Population growth rate" (in percentage) and the "Fertility rate" (the average number of children per woman). We need to analyze this data to identify growth trends and contributing factors.

The provided data:

  • Russia: Growth rate = \(-0.02\%\), Fertility rate = \(1.61\)
  • Brazil: Growth rate = \(0.83\%\), Fertility rate = \(1.81\)
  • Nigeria: Growth rate = \(2.54\%\), Fertility rate = \(5.31\)
  • Global average: Growth rate = \(1.10\%\), Fertility rate = \(2.45\)
  1. Determining Trends and Factors
  2. Fastest Growing Country: Comparing the population growth rates, we have:
  • Russia: \(-0.02\%\)
  • Brazil: \(0.83\%\)
  • Nigeria: \(2.54\%\)

Comparing these values, \(2.54\% > 1.10\% > 0.83\% > -0.02\%\). Thus, Nigeria has the highest population growth rate.

  1. Slowest Growing Country: Similarly, comparing the population growth rates, Russia has the lowest value (\(-0.02\%\)), indicating a population decline.
  2. Contributing Factors for Brazil: Brazil's population growth rate of \(0.83\%\) is below the global average of \(1.10\%\). Its fertility rate of \(1.81\) is also significantly lower than the global average of \(2.45\), which aligns with its modest population growth.
  3. Contributing Factors for Nigeria: Nigeria's population growth rate of \(2.54\%\) is more than double the global average of \(1.10\%\). Its fertility rate of \(5.31\) is more than double the global average of \(2.45\), which is a primary driver of its high population growth rate.
  1. Final Conclusion

Based on the analysis:

  1. The fastest growing country is Nigeria.
  2. The slowest growing country is Russia.
  3. Brazil's lower fertility rate of \(1.81\) compared to the global average of \(2.45\) contributes to its moderate population growth.
  4. Nigeria's high fertility rate of \(5.31\) compared to the global average of \(2.45\) is the primary factor contributing to its rapid population growth.

Final results:

  1. Nigeria
  2. Russia
  3. Low fertility rate (1.81)
  4. High fertility rate (5.31)

Examples

Understanding demographic data helps governments and organizations plan for the future. For example, by analyzing population growth rates and fertility rates, urban planners can determine how many schools, hospitals, and infrastructure projects will be needed in the coming decades to accommodate a growing population, or adjust social services for a shrinking one. Similar to the analysis performed, policymakers look at these indicators to balance resources effectively.
