Describe the concept of population pyramids with examples.
What will be an ideal response?
Answers will vary. A population pyramid is a graphic depiction of a population's age and sex distribution at a given point in time. Mexico is a young country: Much of its population is under age 45 (which also means that many women are in their childbearing years), and there are relatively few people 65 years and older. In contrast, Italy is an old country, and the United States is somewhere in the middle.The shape of the pyramid (a triangle for Mexico, a rectangle for the United States, and a diamond for Italy) has future implications for young and old countries. Italy has a relatively small number of women ages 15 to 44 (in their reproductive years) and a bulge of people ages 45 to 79. This suggests that there will be a scarcity of workers to support an aging population and a greater need for social services for older people than for children and adolescents. Thus, population pyramids give us a snapshot of a country's demographic profile and indicate some of the problems that countries are likely to face in the future.
