These are weighted averages for the OECD area. The so-called “jobs gap” (i.e. the number of additional jobs required to restore pre-crisis employment rates) has also closely tracked the increase in unemployment in most countries, with the correlation between these two measures being 0.97 (see Annex Table 1.A1.4 in OECD, 2011c), consistent with most of the decline in employment resulting in unemployment rather that inactivity. There are, however, a few countries where the jobs gap in mid-2010 significantly exceeded the rise in unemployment, due to falling participation (most notably, Ireland and the United States).
