Frozen LAC-26 Water and Sanitation Monitoring Panel, 2000–2023

This release provides a frozen and auditable World Bank panel for monitoring water and sanitation services in 26 Latin-American and Caribbean economies from 2000 through 2023. The primary dataset contains 624 country-year rows assembled from ten World Development Indicators series: total, urban and rural basic drinking-water coverage; total, urban and rural basic sanitation coverage; under-five mortality; population; GDP per capita; and urban population share.The release includes the exact ten World Bank API JSON responses used to construct the panel, a provenance registry with SHA-256 digests, the derived panel, validation reports, eight analytical validation tables, seven figures, a PowerShell 7 offline replay verifier and a live-reacquisition utility for future versioned vintages.The frozen replay validates all ten source hashes, reconstructs all 624 country-year rows, compares 6,864 numeric cells with the released panel, and reports zero mismatches and a maximum absolute numeric difference of 0. World Bank aggregate codes are excluded by an explicit LAC-26 ISO3 country lock, and missing observations remain missing.The analytical tables and figures are supplied as technical validation and examples of reuse. They include descriptive service levels, urban-rural gaps, cross-country dispersion, descriptive beta-convergence, an associational fixed-effects model relating the WASH service index to under-five mortality, and a descriptive typology. These outputs are not causal estimates.
