This chart of the distribution of the biology workforce is a bit complicated, but somehow dismaying and reassuring at the same time.
As it points out, over half of all biology grad students hope for that tenure-track research position, but only a small fraction will get it. That’s the depressing part. But at the same time, it shows all the alternative career paths: getting a biology Ph.D. does not doom you to becoming a drunken hobo, and not getting a tenure-track position is not a mark of failure.
It’s also a little misleading. “Current non-tenure track academic positions” ought to be relabeled “Serfdom”.
