If I understand you and your parent correctly then what you're each implying about differences in numbers of single men seeking women and single women seeking men within a given area appears to violate at least one of a few basic and seemingly-reasonable assumptions:
1. The ratio of females to males is very close to 1 anywhere in the country.
2. Heterosexuality, homosexuality, etc. is about the same in males and females.
3. Almost everyone who does not identify as "single" is in an exclusive relationship with one person.
I don't live in the US so am quite probably missing something here that you know and I don't. Or my reasoning is mistaken. Could you clarify?
