How these lists are chosen

Both lists use the recorded-sex category with the larger 2025 count. A name needs a published observation in both years being compared. A missing count is skipped, not treated as zero. The absolute list keeps the 50 largest increases among names with at least 200 2025 records. The five-year list keeps the 25 largest ratios of 2025 to 2021 among names with at least 500 2025 records.
