US unemployment has risen steadily since the housing market peaked in 2006. The rate has just crossed the six percent line, and is now as high as it was during the last economic downturn in 2001-02. However, unemployment has risen without an economic slowdown. According to GDP data, the US economy just keeps growing.
This is very strange; the US is now experiencing non-recessionary unemployment. In other words, the economy is getting bigger but it needs fewer workers.
