Again, it's an average, but the average date costs just less than $45. This is across the board, though; predictably, when broken down by gender, men spent a lot more than women per date. Women spent an average of about $34.29 per date, while men spent an average of about $65.69, they reported.

A 2013 study found that the average age of marriage for women was 27 and 29 for men. But in individual states, the data varies considerably. For example, Utah has both the lowest average marriage age for women and men at 23.8 and 25.9, respectively. The District of Columbia wins for the oldest women at 30.2, but New York has the oldest men at 30.6.
