Methodology & sources

Delulu Dating multiplies independent population filters. It's a Fermi estimate for dating — not a prediction about any individual human.

Model: independent filters are multiplied (joint probability under independence). A +12% correlation uplift stops “tall + rich” stacks from being astronomically harsher than a naive model.
Height: Census doesn't publish “mean male height” every year. We use the Population Health Survey (2014/15) male mean (169.5 cm) plus a literature SD (~5.8 cm) for the bell curve. Newer self-reported app polls inflate height — we keep the boring government curve until CHP publishes a replacement bundle.
Income: Census and Statistics Department Annual Earnings and Hours Survey — male wage percentile curve (HK$), interpolated between published points.
Age / marital / education: 2021 Census and thematic reports (simplified age-window and never-married proxies).
Districts: 2021 Census district weights blended into male-share priors — illustrative, not block-level GPS accuracy.
Smoking / kids: broad CHP / survey priors — rounded, not bespoke matchmaking intel.
Flat and car use blunt priors on common deal-breakers. Must own flat keeps about 11% of modeled men. Must keep a car keeps about 24%. Not estate agency research.

This is spicy satire plus public statistics. If you're offended, the numbers still love you. Probably.
