 
<prompt> Population pyramid | Percent |  <response> The broad base depicts the youthfulness of the population. The drop in the female population between ages 10- 14 and 15-19 is a bit steep and could partially be due to some interviewers estimating ages of women to be under the interview cutoff age of 15 to reduce their workload. Similarly, there is an increase in the female population between ages 45-49 and 50-54, which might be due to pushing some of the women out of the age eligibility category. The drop in population between ages 5-9 and under 5 among both males and females reflects a fertility decline, addressed in the chapter on fertility.
