The combined number of persons who were marginally attached or underemployed was approximately 90% of the number unemployed on average in the OECD area in 2007. That share fell to 79% in 2010Q3 due to the small increase in the number of marginally attached workers. Unless otherwise noted, references to unemployment duration in this chapter always refer to the amount of time that currently unemployed persons have been jobless. Most of the currently unemployed will accumulate some additional time in unemployment, so that their currently observed durations (the so-called “interrupted” durations) understate the total time they ultimately will be unemployed (“completed” durations). The share of all unemployed with a year of more of unemployment increased sharply in Denmark, Estonia, Hungary, Ireland, Spain and the United States.
