Get to know your data. Odds are the median value for the tenth percentile
really *is* 0, especially becuase judging by your variable names, it looks
like you're getting frequencies on wages. Read up on "truncation"
"censored data" and "floor effects" and it will make a lot of sense; basic
idea is that since the value of the variable can't go below 0, you'll have
a bunch of people clustered there.
