Freakonomics Radio asks: Is it possible that lack of sleep can explain the income gap?

Here are a few of the questions we ask in this first episode:

+ While the CDC recently declared insufficient sleep a “public-health epidemic,” are we treating the problem as seriously as we ought to be?

+ How legit are the sleep data that have traditionally been collected (hint: not very!) and what is being done to get better data?

+ Are we really sleeping a lot less these days than we used to, or is that argument the product of old, faulty data? And how has our sleep duration changed over time?

+ Who sleeps more: high-income or low-income people? Women or men? Whites or blacks?

+ Could sleep duration be a missing link in explaining the vast difference between health outcomes for whites and African-Americans?
