Your filters look manageable one by one. See what they do in combination with Singaporean data.
The Singaporean Facts Powering Each Filter:
Age distribution: Balanced across age groups — 12% of the adult female population is aged 18–24, while 19% is 65 and older.
Marriage & children: Singapore follows a singaporean (late marriage, low fertility, high singlehood among graduates) pattern. Among Singaporean women aged 25–29, roughly 74% are unmarried and 82% don't have children yet.
Income: Earnings brackets come from Singaporean full-time female worker data. The national median sits at S$50,000, and the top 5% earns S$150,000+.
Body type: National health surveys put the Singaporean female obesity rate at 8%. That leaves 92% of women classified as not obese. Within that group, 46% are in the normal BMI range and 47% are on the slimmer end.
Height: The average Singaporean woman is 160 cm (5'3").
Sexuality: Lower identification rates — about 98% of Singaporean women identify as straight or bisexual, and 96% as exclusively straight.
Eye & hair colour: Brown/Black (97%), Hazel/Other (3%). Hair: Black (95%), Brown (5%).
The bottom line: Still think your checklist is reasonable? Maybe it is — for any single criterion. The lesson of the Delusion Meter is that "reasonable times reasonable times reasonable" often equals "vanishingly rare." Use the results to separate your must-haves from your nice-to-haves, and your odds improve dramatically.
