This just in from Adam Cohen at the UC Berkeley Innovative Mobility Center. As of January 2011:
- In the US: 27 carsharing programs claimed 518,520 members sharing 7,776 vehicles.
- In Canada: 17 carsharing organizations claimed 85,439 members sharing 2,342 vehicles.
During the past year there's been almost no growth in the US carsharing fleet - according to the IMC industry survey, there were 7588 in January 2010 but the the reported membership grew from 388,089 - an increase of 33%. This means that one of the key metrics driving vehicle use - the member to vehicle ratio - grew from 51:1 to 66:1. Although IMC doesn't report individual carshare performance, Zipcar is the dominant influence on these numbers.
In Canada during the past year there was slight growth in fleet numbers - up 199 vehicles. Membership grew by 37% up from 61,944 in Jan. 2010 and member to vehicle ratios increased from 29:1 to 36:1 - no doubt improving the financial position of Canadian operators.
Looking back a little earlier, there been a 33% in US carsharing vehicles since July 2008, and a 40% increase of the carsharing fleet in Canada.
I'll be posting some numbers from Germany shortly.
