St George’s population pyramid! Objective: To create a population pyramid for St George’s School To come to conclusions which describe the population structure of the school How do we go about collecting data for a population pyramid?

Task 1 – Identify key features Narrow at the top which shows that there is a small proportion of elderly people. Wider in the middle which means that people are living longer, less infant mortality. Wide at the top because there is longer life expectancy. 4% of the population is female aged 25-29. Developing Country (LEDCs) Developed Country (MEDCs) Wide at the base which means there are a large proportion of young people in the country. This pyramid is typical of a country such as Kenya or Vietnam. This pyramid is typical of a country such as Italy and Japan. Narrower at the base which means that birth rates are lower.
