Note: Each circle is a country, with diameter proportional to population. The scale on the x-axis is logarithmic. The middle line shows average<br />

life satisfaction for each level <strong>of</strong> per capita GDP while the outer two lines show the same thing, but for two age groups, ages 15 to 25 – the<br />

upper line for most <strong>of</strong> the figure – and ages 60 and over – which is usually the lower line. GDP per capita in 2003 is measured in purchasing<br />

power parity chained dollars at 2000 prices.<br />
