I used a site that had pretty good search parameters, and since I don't have a ton of experience scrutinizing other adults' relationships and relationship desires, didn't quite know how it would turn out.

There were some clear trends in regard to age. They weren't really unexpected, but I wasn't exactly ready for the broad extent of them, given that these were adults and not teenagers.

Search radius = 100 miles (around my city)
of females age 18-35, with a few other restrictions, which returned:
Population size = 460
(18 is the minimum age allowed by the website, so anybody who would date somebody younger than 18 will not be accurately represented.)

Figure 2: http://img338.imageshack.us/img338/6435/dating2.png Age difference that women of a given age are looking for. +0 IS AGE-NEUTRAL.
Figure 3: http://img33.imageshack.us/img33/4870/dating3.png Age multiplier that women of a given age are looking for. 1.0 IS AGE-NEUTRAL.(For example, if a 36-year-old woman is looking for men age 27-54, then her "low" multiplier is 27/36=0.75 and her "high" multiplier is 54/36=1.5)

Figure 5: http://img803.imageshack.us/img803/2607/dating5.png Ratio of women's "high" multiplier to the smallest "high" multiplier of the youngest men they would date. 1.0 IS AGE-NEUTRAL. (For example, if a 36 year old woman is looking for men age 27-54, then her high/low ratio is (54/36)/(36/27)=1.125)

lolz.

At least I found love, it was just with numbers.
