The Bethesda-Rockville-Frederick metropolitan district (as defined by the Bureau of Labor Statistics) has the highest ratio of single women to single men in the country, according to the study, which estimates there are 1.2 single women living alone in the area for every single male.
To come up with the figures, author Jed Kolko first looked at the number of men and number of women not living in dorms, group quarters or other institutions together in large groups. He then subtracted Census estimates of the gay and lesbian population to focus on men and women interested in dating someone of the opposite sex. He also subtracted people older than 65.
East coast power centers are traditionally home to higher ratios of single women to single men.
Washington, DC-VA-MD-WV has the second highest ratio, with 1.12 women living alone per man living alone. Boston, New York, NY-NJ and Raleigh, NC round out the top five.
Kolko’s research shows three Bethesda zip codes with 10 percent to 25 percent more single women than single men. The zip code with the highest ratio of single women to single men in Washington was 20008, which covers upper NW along Connecticut Avenue.
