About IndiaStats.org

Our Mission

IndiaStats.org was built on a simple belief: election data belongs to the people. In India's vibrant democracy, voters, journalists, researchers, and political analysts need reliable, machine-readable electoral information — yet that data has historically been scattered across PDFs, scanned documents, and official portals that are difficult to navigate.

We set out to change that. IndiaStats.org aggregates, cleans, and presents official election data in a fast, modern interface so that anyone with a smartphone can explore the complete political history of their constituency in seconds — not hours.

What We Cover

We currently cover Tamil Nadu in depth — the southern Indian state with 234 assembly constituencies across 38 districts and roughly 6.4 Crore registered voters. Our database includes:

• Complete election history since 1977 — every candidate, their party, votes received, and winning margin for each assembly election cycle.
• Booth-level data — over 46K individual polling booths mapped to their parent assembly constituency, with booth numbers and geographic identifiers.
• Voter demographics — male, female, and third-gender voter counts for each constituency, along with SC/ST reservation status.
• Caste demographic estimates — indicative caste composition data sourced from academic surveys and census research to help contextualise electoral outcomes.
• Political alliance data — party bloc compositions (e.g., DMK alliance, AIADMK alliance) for each election year, with colour-coded visual summaries.
• Interactive constituency map — a GeoJSON-based map of all 234 Tamil Nadu assembly segments, filterable by district and party performance.

We plan to expand coverage to other Indian states in future updates — starting with Andhra Pradesh and Kerala.

Data Sources & Methodology

All election results displayed on IndiaStats.org are sourced from official government records:

• Election Commission of India (ECI) — the primary source for all election results, candidate data, and voter turnout figures (eci.gov.in).
• Tamil Nadu State Election Commission — used to cross-reference constituency boundaries, booth lists, and delimitation orders.
• Census of India — population and demographic figures from the Registrar General of India.
• Academic research & surveys — caste composition estimates are derived from published academic studies and survey organisations. These are clearly labelled as estimates and are not official government figures.

Our data team cross-validates records against multiple sources before publishing. Where discrepancies exist, we default to the most recent official ECI publication. If you spot an error, please contact us — we take data accuracy seriously and aim to correct verified errors within 48 hours.

Who We Are

IndiaStats.org is an independent project built and maintained by a small team based in Tamil Nadu, India. We are not affiliated with any political party, government body, or election commission. Our work is entirely non-partisan — we present data as it is, without commentary or editorial bias.

The platform is built using modern open-source technologies including Next.js, PayloadCMS, and PostgreSQL. The codebase prioritises performance, accessibility, and transparency.

We believe civic data infrastructure is a public good. If you are a researcher, journalist, or civic technologist who would like to collaborate or access bulk data, we would love to hear from you at [email protected].
