I'm not sure if this is factored into your unemployment numbers, but in the USA its very common for all adults to need to work in order to make ends meet.
Whereas in a stronger economy with employment laws protecting employees it'd be much more possible for a family to live comfortably off a single income, making for a lot more "unemployed" adults.
