@onomaverse onomaverse released this 18 Oct 16:23

Open multilingual name datasets — CSV, JSONL, and Parquet (ZSTD). Licensed CC BY 4.0.

Breaking change: absolute counts are no longer published. Frequencies and gender splits ship as shares and ranks only, because the underlying records are coverage-limited estimates, not a census.

  • given-name-frequency, surname-frequency: count removed; use pct_in_country.
  • name-gender-inference: male_count, female_count, total_gendered removed; use p_male / p_female.
  • popular-names-by-country-2026: count replaced by pct_in_country; rank unchanged.
  • Country rows are limited to the source country list (103 countries).
