Figure 7 is a line chart. The horizontal axis shows years which run from 1988 to 2016. The vertical axis is labelled ‘House price-to-income-ratio’ and runs from a value of 0 up to 6. There are two lines on the chart, one for each of the two groups of owners: first-time buyers and existing owners. The line for first-time buyers starts at about 3 in 1988 and remains fairly stable until 2001 at which point it rises sharply to reach about 4.5 in 2004 and remains at that level until 2016 (with a small glitch down to 4 in 2006). The line for existing owners starts higher at 4 in 1988 and goes slightly down to 3.5 in the mid-nineties then back to 4 in about 2001 after which it too rises sharply to reach a peak of 5.5 in 2004 and remains just above 5 all the way to 2016.
