Describing Pie Charts (1)

Pie Charts normally illustrate proportion


Bar Chart


Pie Charts normally show proportion, which can be measured in percentages or fractions.

This chart shows the relative size of populations of countries of the European Union in 2007. So we can only make comparisons; we cannot say anything about change.

We can see that the country with the largest population was Germany with 16.6% of the European Union's population. We can also see that the second largest population was that of France with 12.8% of the population.

We do NOT know from this chart which country has the smallest population because the 21 smallest countries are included in one group. (If you're interested, it is Malta with less than 0.1 per cent.)

You can see that the four largest countries (Germany, France, the United Kingdom and Italy) together make up more than half of the European Union's population.

You CANNOT say that Poland has the smallest population: 21 other countries have populations smaller than Poland's.

The twenty-one smallest countries of the European Union make up nearly 30% of the population.
