Long description

Figure 6 is a line chart. The horizontal axis shows years from 2006 to 2018 in two-yearly intervals. The vertical axis is labelled ‘Index value’ and runs from a value of 60 up to 180. There are four lines on the chart, one for each of the following countries: Germany, Sweden, United Kingdom, United States. There is also a horizontal line corresponding to the value 100 labelled ‘Long-run average’. The line for Germany starts at a value just above 80 in 2006 and climbs gently to a value of around 88 by 2017. The line for Sweden starts at 113 in 2006 and fluctuates between that and around 124 until 2010 when the line starts to climb steeply reaching nearly 160 by 2017. The line for the UK starts around 130, rises to nearly 140 in late 2007, then falls to 112 by mid-2009. After that it fluctuates in a narrow range until 2013 when its starts to climb from a low point of 109 to reach 130 by 2017. The line for the USA starts at 116 in 2006 and fails fairly steadily to a low of 81 in 2012. Since then it has gently climbed to reach 99 by 2017.
