CI# 22 -- Economic Indicators

As the economy is starting to recover (or isn't, depending on who you're talking to), we're hearing things like "green shoots," "consumer discretionary spending," "housing starts," and a lot of other jargon. So I was wondering, Is there some kind of "economic indicator" we all can easily understand?

Turns out, yes.
