If a population has many more young women entering the reproductive years than older women leaving the reproductive years, which of the following statements is not true?

Its likely to be a more developed country.

Explanation:

Fertility rate is an indicator used to estimate the average number of children a woman could have until the end of her reproductive period.

Therefore the fertility rate helps in the analysis of the reproductive conditions of women in a given locality. An analysis of the world's fertility rate results showed that women are having fewer children worldwide. This tendency is expressed by the greater insertion of women in the labor market, greater information on family planning, the use of contraceptive methods, greater sex education.

Therefore the false alternative is that this scenario written in the question is from a developed country, as research has shown that the fertility rate of young women in developed countries is lower due to greater information and better social and economic conditions.
