Car-Free Households in San Francisco Above 30 Percent

According to the new San Francisco Municipal Transportation Agency 2010 Transportation Fact Sheet, the number of car-free households increased. Last year [pdf], data show that 29.8 percent of households had no car, a number than climbed to 30.3 percent this year [pdf]. Oddly, it seems the shift came mostly from households with one car, as some migrated to car-lessness, while others increased the numbers of cars in their households. In real numbers, there was only a slight uptick in households with no cars, or nearly 2,000. About 1,000 more households had two cars or more, while 4,000 more had at least three cars.

What factors do you think led to these numbers? Was it car-share, more biking, more walking, more telecommuting, higher unemployment? Remember to take into account that these numbers are from the 2008 and 2009 census data, respectively.

Tell me what you think in the comments. How do you think this will change next year?
