Xatori ranks U.S. cities by the number of publicly accessible charging stations per 100,000 residents. The resulting list:

1. Portland (11.0 chargers per 100,000 residents)
2. Dallas (10.6 per 100,000)
3. Nashville (8.2 per 100,000)
4. SF Bay Area (6.6 per 100,000)
5. Seattle (6.5 per 100,000)
6. Orlando (6.3 per 100,000)
7. Austin (5.3 per 100,000)
8. Tucson (5.3 per 100,000)
9. Honolulu (5.1 per 100,000)
10. Washington, D.C. Area (4.7 per 100,000)

Xatori credits the seemingly unlikely high rankings of Dallas and Nashville to a couple of significant factors. Dallas' political leaders exhibit a remarkable level of support for building an EV infrastructure, while Nashville has a lot of public chargers due to the impending opening of a Nissan LEAF factory in Smyrna, 25 miles away. Portland leads the list because, well, it's Portland: a small, compact city with a very high percentage of environmentally concerned people affluent enough to buy a new car in the last couple of years.

Xatori doesn't break down its figures for the San Francisco Bay Area by city, but its PlugShare map indicates that charging stations are well-distributed through San Francisco, the East Bay, and San Jose areas, with even more in the eastern suburbs stretching to Sacramento.

Xatori is the company behind the "PlugShare" phone app and EV social network, in which EV enthusiasts can share their own charging stations to other drivers -- an interesting concept that may well reduce prospective EV buyers' range anxiety.
