This FRED graph divides unemployed (civilian) workers according to the duration of their unemployment spell. The number of those unemployed for 27 weeks or more is still very high, while the other categories have recovered to normal levels. This level of persistently elevated unemployment is different from that during previous recessions, and there may even be some structural component to it, given how the long-term unemployed are still struggling.
How this graph was created: This graph uses a new feature of FRED: stacked areas. (You can also choose stacked lines or histograms.) Try this: Create a graph with several series, then select "normal" stacking in the graph settings. "Percent" stacking would show the shares of each category in the total number of civilians unemployed. Or try it by clicking on the "Customize" link below the graph.
