Let's analyze the given data step by step to answer each part of the question.
1. Population Growth Rate:
- Russia: -0.02%
- Brazil: 0.83%
- Nigeria: 2.54%
- Global average: 1.10%
From these growth rates, we can determine:
- The country with the highest growth rate (fastest growing) is Nigeria with 2.54%.
- The country with the lowest growth rate (slowest growing) is Russia with -0.02%.
2. Determining Contributing Factors:
The table also provides fertility rates for the three countries and the global average:
- Russia: 1.61
- Brazil: 1.81
- Nigeria: 5.31
- Global average: 2.45
Brazil:
- The factor most likely contributing to Brazil's population growth rate is its fertility rate. Although it is slightly below the global average (1.81 vs 2.45), it is significant enough to explain Brazil’s moderate growth rate compared to Russia.
Nigeria:
- The factor most likely contributing to Nigeria's high population growth rate is also its fertility rate. With a fertility rate of 5.31, which is much higher than both the global average and the rates in Brazil and Russia, high fertility is the leading factor contributing to Nigeria’s rapid population growth.
Therefore, summarizing the answers:
- The country growing the fastest is Nigeria.
- The country growing the slowest is Russia.
- The factor most likely contributing to Brazil's population growth rate is the fertility rate.
- The factor most likely contributing to Nigeria's population growth rate is also the fertility rate.
