Our first essay.
In 2006 the Delimitation Commission rejected every Shiv Sena objection to its draft, then adopted a plan for Pune’s four Lok Sabha seats sent by three men on the ruling side (NCP-INC Alliance).

The Commission broke from the letters once. It moved Pune’s Hadapsar ward into rural Shirur.
Baramati stayed exactly as asked. Shirur’s Congress-NCP lead fell from 1,65,146 to 39,379.
Seat numbers were frozen. What Baramati gained, its neighbour paid for.
Four more states live on Boundaries: Bihar, Odisha, Jharkhand, Chhattisgarh.
22 States live now. Both maps, every seat, territory measured across the redraw and everything is interactive.

4/n Three across four states, and Odisha has the only pair that swapped in opposite directions.
Reserved seats normally stay in their category or go general. Changing from Scheduled Caste to Scheduled Tribe, or back, is rare.
Odisha did both at once in 2008. Malkangiri went from SC to ST. Raghunathpali went from ST to SC.
Across Bihar, Jharkhand and Chhattisgarh combined, only two other seats switched category, both in the same direction. Odisha is the only state where reservation moved between the two communities in both directions at the same redraw.

Madhya Pradesh also got an upgrade today. It went live with no order-derived lineage at all. It now has 193 of 230 seats linked from the 1976 and 2008 order texts, and statutory extent text on both sides.
Every seat record says which basis its lineage rests on.

Uttarakhand's assembly did not exist in 1976
The 1976 order gave the hill districts 22 of Uttar Pradesh's seats. Those 22 men formed the interim assembly when the state was created in 2000.
The 70 seat map was drawn by the Election Commission in 2001 and contested exactly twice, in 2002 and 2007, before 2008 replaced it.

Every seat record shows where its ground went, how much, and whether we read that from the order text or inferred it. We always say which.

Four more assemblies are now live on boundaries.in: Madhya Pradesh, Tamil Nadu, Delhi and Jammu & Kashmir.
Both maps, seat by seat, with the territory tracked across the redraw. Free, no login.
Boundaries just got a research upgrade.
Seven things we shipped for anyone working on Indian electoral geography:
→ Territory lineage with measured areal shares — not just which seat a constituency became, but what percentage of its area went where. Both directions, per seat, with a confidence marker on each link.
→ CSV and JSON download — both delimitation orders, every live state, machine-readable. Straight into R or Python, no scraping.
→ One-click citation with live access date — formatted and ready to paste into a footnote.
→ Print stylesheet and dark mode — A4-ready maps with the district ledger intact for fieldwork and presentations. Dark mode for late-night reading on a phone.
→ Statutory extent text — the actual boundary description from the 1976 and 2008 orders, quoted per seat. Primary source, no PDF hunting.
→ Status field — every seat tagged continuing, renamed, abolished, or new. A clean taxonomy for before-and-after comparisons.
→ City insets — Bengaluru, Lucknow, Kanpur, Varanasi broken out at a readable scale. Urban seats are invisible at full-state zoom. Now they are not.
All of it free, no login, no paywall.

Uttar Pradesh is live on Boundaries. 403 seats before 2008, 403 after, both maps drawn to the same projection.
The largest assembly in the country, and the most complex map we have published.
Every seat carries its full election history. 1980 to 2007 on the old map, 2012 to 2022 on the new one. Winner and party for each.
No other state on the site has this yet.
Click any election year in Plate III and the map colours by who won each seat.
Move through 1980, 1989, 1993, 2007, 2012, 2022 in order. Congress recedes, Mandal reorders the state, BSP peaks, the BJP consolidates. Same map, forty years.
Territory lineage is published for all 403 seats. Where each old seat went, what each new seat was built from, with measured percentages.
Uttar Pradesh is the tenth state.
