About 8.1 percent of U.S. workers have commutes of 60 minutes or longer, and nearly 600,000 full-time “mega commuters” travel at least 90 minutes and 50 miles. The average one-way daily commute for workers across the country is 25.5 minutes, and one in four commuters leave their county to work.

These figures come from the U.S. Census Bureau’s annual American Community Survey, which was released Tuesday.

The San Francisco area heads the list, with 2.09 percent of its workforce categorized as mega commuters. The greater New York City area comes in second, with 1.9 percent; followed by Greater Washington, D.C. (1.89 percent); Trenton/Ewing, N.J. (1.4 percent), and Greater Los Angeles (1.25 percent).

Sonoma County figures weren’t available.

Mega commuters were more likely to be male, older, married, make a higher salary and have a spouse who does not work, according to the report. Of the total mega commuters, 75.4 percent were male and 24.6 percent women. Mega commuters were also more likely to leave for work before 6 a.m.
