If you’re single and looking to mingle, then you should head to the West Coast if you’re a straight woman, but stick to the East Coast if you’re a guy.

A new study from the Martin Prosperity Institute finds that single women far outnumber single men in East Coast cities like New York, Atlanta, Miami, and Boston, whereas single men are a greater part of the population in West Coast metropolises like L.A., San Diego and Seattle.

Midwestern cities like Chicago, St. Louis and Dallas also have more single women than single men, although by a lesser margin that most East Coast cities.
