Average Age of Automobiles in the US
By Kevin
Inspired by Buzzcut's comment on Steve Verdon post on smog, I would like to look at the mean age of autos in the US, and the median age of autos in the US. Since the mean is persistently greater than the median (as expected), the distribution is persistently skewed towards older cars. Is this distribution becoming less skewed over time?
