To solve the given problem, let's analyze the provided data and answer each question step-by-step.
1. Which country is growing the fastest?
- We look at the population growth rates for Russia, Brazil, Nigeria, and the global average:
- Russia: [tex]\(-0.02\%\)[/tex]
- Brazil: [tex]\(0.83\%\)[/tex]
- Nigeria: [tex]\(2.54\%\)[/tex]
- Global avg.: [tex]\(1.10\%\)[/tex]
- The country with the highest growth rate is growing the fastest.
- Among these, Nigeria has the highest population growth rate of [tex]\(2.54\%\)[/tex].
Answer: Nigeria
2. Which country is growing the slowest?
- Again, we examine the population growth rates for the slowest growth.
- Russia has the lowest growth rate of [tex]\(-0.02\%\)[/tex], indicating a negative growth rate.
Answer: Russia
3. Which factor most likely contributes to Brazil's population growth rate?
- For Brazil, we look at the fertility rate and life expectancy:
- Fertility rate: [tex]\(1.81\)[/tex]
- Life expectancy: [tex]\(73\)[/tex] years
- A key factor influencing population growth is fertility rate.
- Although Brazil’s fertility rate ([tex]\(1.81\)[/tex]) is slightly below the global average ([tex]\(2.45\)[/tex]), it still contributes significantly to its population growth.
Answer: Fertility rate ([tex]\(1.81\)[/tex])
4. Which factor most likely contributes to Nigeria's population growth rate?
- For Nigeria, consider the fertility rate and life expectancy:
- Fertility rate: [tex]\(5.31\)[/tex]
- Life expectancy: [tex]\(52\)[/tex] years
- Nigeria has a very high fertility rate ([tex]\(5.31\)[/tex]), which is well above the global average ([tex]\(2.45\)[/tex]). This high fertility rate is a major contributor to its high population growth rate.
Answer: Fertility rate ([tex]\(5.31\)[/tex])
In summary, based on the provided data:
- Fastest Growing Country: Nigeria
- Slowest Growing Country: Russia
- Brazil's Growth Factor: Fertility rate ([tex]\(1.81\)[/tex])
- Nigeria's Growth Factor: Fertility rate ([tex]\(5.31\)[/tex])
