Question: 4

In which year is the per capita income the highest?

Show Hint

For questions asking for the absolute highest or lowest value over a period, a quick scan of the trend in the bar graphs can often give you a probable answer, which you can then verify with calculation. Here, both income and population are rising, but income is rising faster, so the latest year is the most likely answer.
