Back to the topic of the thread....these are new unemployment claims. It doesn't mean unemployment has gone down, it means generally that the rate at which people are losing their jobs is going down. At the point 100% of Americans were unemployed, for example, this indicator would show zero new unemployment claims. That wouldn't indicate the economy had gotten any better!
In this case it just indicates things aren't getting worse quite as fast as they were. Not that things are getting better, wrt unemployment at least.
