Based on the data in the chart, which statement is true?

A. Niger has twice as many births as deaths per 1,000 people, but the life expectancy is only 52.6 years, resulting in a young median age.
B. Niger's life expectancy is only 52.6 years; therefore, the country must have a young median age.



Answer :

To determine which statement is true based on the provided data, let's break down each statement and analyze if it holds true using the given statistics for Niger.

### Statement A:
"Niger has twice as many births as deaths per 1,000 people, but the life expectancy is only 52.6 years, resulting in a young median age."

1. Checking if Niger has twice as many births as deaths per 1,000 people:
- Birth rate in Niger: [tex]\( 51.6 \)[/tex] births per 1,000 people
- Death rate in Niger: [tex]\( 20.26 \)[/tex] deaths per 1,000 people

We need to verify if the birth rate is at least twice the death rate:
[tex]\[ 51.6 \geq 2 \times 20.26 \][/tex]
Calculating the right-hand side:
[tex]\[ 2 \times 20.26 = 40.52 \][/tex]
Comparing:
[tex]\[ 51.6 \geq 40.52 \][/tex]
This condition is true.

2. Checking life expectancy:
- Life expectancy in Niger: [tex]\( 52.6 \)[/tex] years

The statement mentions this value correctly.

3. Checking the median age:
- Median age in Niger: [tex]\( 15.2 \)[/tex] years

The statement correctly identifies that the median age is young.

Since all parts of Statement A are confirmed with the data, this statement can be true.

### Statement B:
"Niger's life expectancy is only 52.6 years; therefore, the country must have a young median age."

1. Checking life expectancy:
- Life expectancy in Niger: [tex]\( 52.6 \)[/tex] years

The statement mentions this value correctly.

2. Checking the median age:
- Median age in Niger: [tex]\( 15.2 \)[/tex] years

The statement mentions that Niger has a young median age which matches the provided data.

However, the logical implication in Statement B is that a low life expectancy directly causes a young median age, which is not necessarily true. A young median age is influenced by other factors such as high birth rates and population age structure.

### Conclusion

Based on the given data and the analysis above, we can safely conclude that:

- Statement A is entirely validated by the provided statistics and holds true.
- While Statement B contains correct data points, its implication is more interpretive and less directly supported by the provided facts.

Therefore, the true statement is:
[tex]\[ \boxed{A} \][/tex]
