Archived US retailer size charts and Korean garment sizing standards against anthropometric surveys, 1999-2026: code and derived data

Code and derived data for a study of archived US retailer size charts and Korean garment sizing standards against anthropometric surveys. The archive holds the harvesting, parsing and analysis pipeline for web-archived US retailer size charts (1999–2026): the harvest manifest with the Wayback timestamp and SHA-256 of every capture, the parsed chart records, page states and label-level series with the exclusion lists, the chart revisions with their audit against the archived pages, the coverage of the printed size ranges, the decomposition of label changes against age-standardized NHANES distributions with its sensitivity runs, and the endpoint audit; the population quantile grids derived from NHANES, Size Korea (waves 5–8) and ANSUR II; the designation tables rebuilt from the 2004, 2009, 2019 and 2025 editions of KS K 0050 and KS K 0051 with the cross-edition identity test, coverage, reference-dimension and rebuilt-grid results; the tables and figures, the structural validator and the number registry. Archived page bodies, the standards' text layers and survey microdata are not redistributed; README.txt gives the sources and the re-fetch procedure. Code MIT, derived data CC BY 4.0.
