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?



Answer :

GinnyAnswer
Let's analyze the given data systematically to answer each question.

### 1. Which country is growing the fastest?

We have the population growth rates for the given countries:
- Russia: -0.02%
- Brazil: 0.83%
- Nigeria: 2.54%
- Global avg.: 1.10%

To determine the country growing the fastest, we look for the highest population growth rate.

- Russia: -0.02%
- Brazil: 0.83%
- Nigeria: 2.54%
- Global avg.: 1.10%

Among these, Nigeria has the highest growth rate of 2.54%.

Answer: Nigeria

### 2. Which country is growing the slowest?

Similarly, to determine the country growing the slowest, we should look for the lowest (most negative or least positive) population growth rate:

- Russia: -0.02%
- Brazil: 0.83%
- Nigeria: 2.54%
- Global avg.: 1.10%

Russia has the lowest growth rate of -0.02%.

Answer: Russia

### 3. Which factor most likely contributes to Brazil's population growth rate?

To understand the factors that contribute to Brazil's population growth, let's consider the other given data:
- Fertility rate: 1.81
- Life expectancy: 73 years

Brazil's fertility rate and life expectancy are close to the global averages (Fertility rate: 2.45, Life expectancy: 68 years). Therefore, it is reasonable to infer that both factors (fertility rate and life expectancy) contribute to its population growth rate.

Answer: Fertility rate, Life expectancy close to global avg.

### 4. Which factor most likely contributes to Nigeria's population growth rate?

For Nigeria, let’s consider:
- Fertility rate: 5.31
- Life expectancy: 52 years

Nigeria’s fertility rate is significantly higher than the global average (2.45). This high fertility rate is a strong factor contributing to Nigeria’s high population growth rate, despite its lower life expectancy (52 years versus a global average of 68 years).

Answer: High fertility rate

### Summary:
- Fastest growing country: Nigeria
- Slowest growing country: Russia
- Brazil's population growth factor: Fertility rate, Life expectancy close to global avg.
- Nigeria's population growth factor: High fertility rate
