Based on these data, what happened to the world population during this time frame?

A. The number of people added to the population yearly decreased.
B. The median age of the population increased.
C. The population got a bit younger.
D. The population size got a bit smaller.



Answer :

To determine what happened to the world population during this given time frame, let's carefully analyze the provided data:

1. World Population:
- The data gives us the world population at a specific point in time, which is 6,126,622,121.

2. Number of People Added Annually:
- This number is 78,299,807 people per year.

3. Annual Growth Percentage:
- The annual growth percentage is 1.33%.

4. Median Age:
- The provided median age of the population is 26 years.

5. Fertility Rate:
- The fertility rate is 2.74.

Now, let's evaluate each of the options based on the provided data:

A. The number of people added to the population yearly decreased.
- The data shows that 78,299,807 people are added annually to the population. However, there is no information provided about previous years' data to determine if this number represents an increase or decrease. Therefore, we cannot conclude if the annual addition of people has decreased.

B. The median age of the population increased.
- The median age is provided as 26, but without previous data on the median age, there is no comparison point to determine if it has increased or decreased.

C. The population got a bit younger.
- While the median age is given as 26, there is no earlier data to compare and verify if the population has gotten younger.

D. The population size got a bit smaller.
- The data indicates that the population size is increasing due to the addition of 78,299,807 people annually and a growth rate of 1.33%. This suggests that the population size is not getting smaller.

Given the analyzed information, we conclude that:
None of the given options can be accurately determined from the provided data.

Thus, the correct conclusion is:
None of the given options can be accurately determined from the provided data.
