The Daily News reports that "[i]t's official: New York has the hottest singles scene in America. The U.S. Census Bureau released a report yesterday showing New York has a greater percentage of bachelors and bachelorettes than any other state - and most of the singles are in the city." Also of note is the fact that there are "86 unmarried men for every 100 unmarried women."
So according to my (extremely non-scientific) calculations, at least 10% of the single male population is gay, and at least 85% of the straight men are jackasses. That leaves approximately 12 straight, non-jackass men for every 90 women (I'm calculating 10% gay on that side of the equation as well).
