Comparing economic growth across the world

Pupils explore changes in GDP and GDP per capita to gauge economic performance and individual prosperity in various regions.

Scenario

You are interning at a bank and your first project is to research economic growth in various cities and countries around the world. You learn that economic growth is typically measured in changes in gross domestic product (GDP), which refers to the financial value of goods and services produced by an economy. Additionally, your manager explains that you should also consider GDP per capita, which is calculated by dividing an economy’s GDP by its population, in order to better understand the average economic output of each individual person within an economy.
