Method and limits
Counted rows come from national registration sources that publish male and female totals. The attested-country list also includes sources that confirm presence but do not publish a sample size. Those two evidence types are kept separate.
Name data describes a population-level association. It does not identify an individual person's gender. Preserve unknown and low-confidence results, and do not use name inference for employment, medical, financial, insurance, legal or eligibility decisions.
