Question

Look at the age-structure pyramids. The numbers between the bars (in the middle of the graphs) serve as the y-axis. What do these numbers represent? a) the age classes, in 5-year ranges b) the number of people born in a particular year c) the total population, in millions the population of males and females d) the percentage of the population in each age class.

Answer 1

A) The age classes, in 5-year ranges

Step-by-step explanation:

The number between the bars are the age classes, and the bars represent the populartion, in millions, belonging to the corresponding age class.

A population pyramid like the one attached below usually does not show the number of people born in a particular year. However, this information can be estimated by looking at the year the population pyramid was elaborated, and substracting from that year the corresponding ages illustrated in the pyramid.
