Pyramid 2 shows Italy's population in 2015, this population pyramid is shaped like a cup What does the shape say about the distribution of the population? The shape of pyramid 2 indicates that there will be a population decline in Italy in the years to come. this could be because Italy is getting further along into industrialization. These are strong signs that factors like education are beginning to have an effect on household sizes because people are now beginning to educate themselves on safer contraceptive methods. It could also be that the reproductive population understands that a higher education such as a college degree can benefit them more in the long run, leaving the choice of reproducing early on pause. Also as social views begin to change, so do gender roles, a decrease in birth rates could show that women are beginning to focus on other opportunities such as education or work, rather than starting a family. Which age group has the highest percentage of the population? The age group with the highest population in age in pyramid 2 is the "Reproductive" population ages 15-44. Which age group has the lowest percentage of the population? The lowest age group in pyramid 2 is the "Pre-reproductive" age group, ages 0-14.

Italy's decline in population will occur in a slow manner, it is interesting to see how social changes have affected population growth and how gender roles are beginning to change as newer generations are born. |
