Spend lots of in-person time with eligible members of your preferred demographic. That's basically it.
That's why school is ideal (surrounded by eligible people of the same age, usually with little life baggage); but work, religion, sports/hobbies, or preferably a combination, are also time-tested hunting grounds. I used a combination of school and sports.
Dating can't be reduced to a spreadsheet. Many of the long-term marriages I know about (including mine) would not have survived that degree of analytic scrutiny up front. Conversely, of the divorced people I know, many looked like good matches "on paper."
Humans are still social monkeys, and it takes a while to figure out compatibility.
