The multi-regional input\u2013output (MRIO) model is a widely used tool for describing intersectoral supply chains within complex economic systems. However, a comprehensive MRIO model for one of the world\u2019s largest emerging economies has been lacking. Here, we develop a time-series MRIO dataset for 32 Indian states covering 2011\u20132019, comprising 66 sectors and five final demand categories. Using a hybrid approach that integrates multiple data sources with entropy-based estimation, we construct consistent MRIO tables aligned with India\u2019s official national supply\u2013use tables. The dataset reveals the evolution of domestic supply chains during India\u2019s critical growth period between the global financial crisis and the COVID-19 pandemic. It provides a foundational resource for studies on industrialisation, regional inequality, environmental impacts, and spillover effects across regions.<\/jats:p>","DOI":"10.1038\/s41597-026-07227-x","type":"journal-article","created":{"date-parts":[[2026,4,24]],"date-time":"2026-04-24T07:56:52Z","timestamp":1777017412000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["India Multi- Regional Input-output Dataset for 32 States from 2011 to 2019"],"prefix":"10.1038","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0818-7933","authenticated-orcid":false,"given":"Heran","family":"Zheng","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yazhuo","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenqiang","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenyu","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8708-0485","authenticated-orcid":false,"given":"Jing","family":"Meng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dabo","family":"Guan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,4,24]]},"reference":[{"key":"7227_CR1","doi-asserted-by":"publisher","unstructured":"Huang, Q. et al.
