Trucks in Georgia

The least populated Georgia counties tend to have the greatest percentage of pickup trucks compared to other registered vehicles.

Can I have a duh from the audience?

I know, it seems obvious, but in playing with some other data I came across the percentage of all motor vehicles in each Georgia county that happen to be trucks. For you statistical nerds out there, the correlation between population and percentage of vehicles that are trucks is -.72. That's a strong negative correlation, meaning of course the greater the number of folks who live in a county, the fewer pickups (which are found, obviously, in more rural counties with fewer folks who live there).

The table below ranks counties by percentage of trucks among all vehicles and includes the rank in population (out of 159 counties). As you can see, the Trucking Top 10 is an imperfect mirror image of the Population Top 10.

Truck
Rank

County
Population
Rank
  1
Echols
153
  2
Appling
  93
  3
Atkinson
140
  4
Glascock
155
  5
Bacon
121
  6
Irwin
130
  7
Johnson
128
  8
Baker
154
  9
Montgomery
133
10
Wilsox
134

I could have flipped this. The #1 population county, Fulton, is #159 (last) in proportion of trucks among all registered vehicles. Indeed the four most populous counties are last when it comes to trucks.

Locally, Clarke County (Athens) is #19 in population but #153 in trucks (17.6 per 100 vehicles). Oconee is #52 in population, #132 in trucks (22.7 per 100 vehicles).

Just so you know, 35.2 percent of all vehicles in Echols are trucks, this in a county with 4,057 or so souls.
