Equality between the sexes, so good in theory, doesn’t necessarily deliver in practice:

Marriage rates have steadily declined over the past few decades, and now researchers from Cornell University are offering up a possible explanation: there just aren’t as many economically-attractive men for unmarried women to meet as there used to be.

Previous studies had attempted to answer why marriage rates are on the decline, but most focused solely on gender ratio discrepancies as opposed to looking into the specific socioeconomic characteristics that make a particular man and woman a good match.
