Question

thailand 1960
age
105
age
65
age
25
which of the following conclusions about the population are supported by the age structure? select the three correct responses.
a. women in this population are having, on average, more than three children each.
b. the population has a large proportion of seniors over the age of 65.
c. the population has a large proportion of youth under the age of 25.
d. the birthrate in this population is very low.
e. the population is in a period of rapid growth.

Explanation:

• Option A: In a population pyramid with a wide base (indicating a large number of young people), it suggests a relatively high birth rate. If there are many young people, it implies that women are having enough children to sustain this growth. A wide base often corresponds to a situation where women have more than three children on average (to maintain the growth pattern shown in the pyramid).
• Option C: The wide base of the population pyramid (the lower part, which typically represents the younger age groups) shows that there is a large proportion of youth under the age of 25.
• Option E: A population pyramid with a wide base and a narrow top (like the one for Thailand in 1960) is characteristic of a population in a period of rapid growth. The large number of young people will grow up and have their own children, continuing the growth trend.

• Option B: The pyramid has a narrow top. The top of the pyramid represents the older age groups (over 65). A narrow top indicates a small proportion of seniors over 65, not a large proportion.
• Option D: A low birth rate would result in a more rectangular - shaped population pyramid (like in some developed countries with stable populations). The wide base of this pyramid indicates a relatively high birth rate, not a low one.

Answer:

A. Women in this population are having, on average, more than three children each.
C. The population has a large proportion of youth under the age of 25.
E. The population is in a period of rapid growth.
