The Standard Criterion is very simple. It's basically a very general peer group criterion, based in part on the observation that as we get older, our potential peer group gets larger, as we become more willing to associate with people in a larger age range. The choice of 25% is rather arbitrary, and actually it would be a simple enough thing to change on the form below, so I will.
|Older criterion interval||Younger criterion interval|
|Born on or after||Your birthday||Born on or before|
