Bostonians shell out a higher portion of their income for rent than tenants in any other U.S. city, a published report said Sunday.

Rents in the greater Boston area jumped 6.1 percent last year, a bigger increase than in any other major metropolitan area except Washington, D.C., The Boston Sunday Globe reported, quoting data from the U.S. Bureau of Labor Statistics.

In Washington, rents jumped 7.2 percent, while New York's rents went up 5.4 percent in 1988, according to the Bureau of Labor Statistics. Chicago's rent climbed 5.3 percent, Baltimore's 4.9 percent and San Francisco's tenants paid an extra 4.3 percent. Nationwide, rents went up 3.3 percent.

A study by an independent research firm in California found Boston's rents among the highest in the country, the Globe reported. With subsidized units included, Boston's median rent was $586 per month, on a par with San Francisco but considerably higher than levels in most major cities, the group, Sound Advice, said.

Boston residents spend 21.3 percent of their household income on rent, the group said, while San Francisco tenants pay 19.8 percent of their income.

Washington's median rent was the highest, at $601 per month, with its residents devoting 18.3 percent of their income to rent.
