Open datasets, visualizations, and exploratory tools
Complete ethnic composition data from China's 7th National Population Census, including regional breakdowns by province and comparisons with 2010 census data.
Cross-referenced mapping between China's officially recognized ethnic groups and Joshua Project's people group database, with cleaned religion and language classifications.
Reusable constituency/region map component tested with India (Lok Sabha/Vidhan Sabha), US states, and China provinces. Configuration-driven, zero country-specific code.
Interactive comparison of ethnic population changes between China's 2010 and 2020 censuses. Identify growing and declining communities across all 31 provinces.
All datasets are sourced from official publications and reputable research organizations. Where automated matching is used (e.g., census-to-Joshua Project mapping), results are manually validated and false positives are removed.
