The "Drop" in Unemployment

Do you follow Sociological Images? If not, you seriously should. In a recent post, they dig into the Bureau of Labor report that unemployment rates have dropped to 9%. While the post goes into much more detail, detail that is worth the ninety seconds or so worth of reading, I learned this in my Intro to Sociology class at community college; unemployment does not, I repeat, does not measure the percentage of the population that is currently unemployed. Don't let the politicians and/or the infotainment industry bullshit you.
