The states did not all publish the same tables, so the site does not use one count everywhere. This page says what each count means, what it takes in and what it leaves out, so that a figure on any page can be read for what it is. Each state's method page names the exact tables behind its figures, and Downloads has every table.
Words we use
The site keeps two words apart. A name on the roll before the revision whose enumeration form did not come back is left off the draft, or excluded from it. A name taken off the roll by an officer's order after the draft, on an objection in Form 7 or on the officer's own motion, is deleted. Where both stages are counted together, as in Bihar, the site says left off or deleted. A difference between two published rolls is the fall in the roll, which is neither.
The two are different acts in law. Section 22 of the Representation of the People Act, 1950 lets the electoral registration officer delete the entry of a person who is dead, has ceased to be ordinarily resident or is otherwise not entitled to be registered, and before deleting it on any ground but death the officer "shall give the person concerned a reasonable opportunity of being heard". An order deleting a name can be appealed to the District Magistrate and then to the Chief Electoral Officer under section 24. A name left off the draft went through none of these steps. The Commission's guidelines of 24 June 2025 say only that the names of electors "from whom Enumeration Forms are not received will not be included in the draft roll" (paragraph 4(b)), and the remedy for such an elector is a claim on Form 6 with the declaration (paragraph 4(c)).
The Supreme Court drew the same line. Its judgment of 27 May 2026 (2026 INSC 564) says that "such non-inclusion is not tantamount to a final deletion, but is only a provisional step, preceding the statutory process of claims and objections" (paragraph 134), and it says Bihar's 65 lakh "stood excluded from the draft roll" (paragraph 10.9).
The authorities do not always keep to the line themselves. The same judgment speaks of persons "whose names have been erroneously deleted on the ground that they are absent, dead, shifted or in duplication" (paragraph 186(h)), and does not say whether it means the names left off the draft. The Commission's press release of 30 September 2025 counts both groups as "removed" in its table, while the text of the same release calls the first group names "not included in draft roll". Where a page quotes a court, the Commission or a newspaper, it keeps their words. The site's own sentences keep the line. The steps open to an elector at each stage are on Left Off the Roll? What to Do.
How the revision runs
A Special Intensive Revision rebuilds a state's electoral roll from the roll in force when it starts, which the site calls the roll before the revision. A booth level officer takes an enumeration form to every elector on that roll. An elector whose form comes back stays on the roll, and one whose form does not is left off the draft roll that follows. After the draft, electors can claim to be added (Form 6) or object to a name (Form 7), electors sent a notice are heard, and the final roll is published at the end. Each state's dates are on How the SIR Was Run and Where the Revision Stands.
Assam held a Special Revision, which ran on different rules. Existing electors filled in no form, and the names it found to be dead, shifted or entered twice were flagged for deletion. The Assam pages call them flagged throughout, because no table says they were taken off the draft.
Names left off the draft
The names on the roll before the revision that are not on the draft roll. Most states published this count, by state and often by district or constituency, and most pages lead with it. It is given per 100 electors on the roll before the revision.
Officers file these names under a few headings, usually absent, shifted, dead and already enrolled elsewhere, sometimes with "other". Delhi's table calls them the forms not collected. When the site adds the names left off across states, it folds the headings into the three that every state reported, which are dead, then shifted, absent or other, and then enrolled more than once.
The reason beside a name
The reason is what the officer wrote down when the form did not come back, and nobody checked it. It is useful for seeing the pattern of what officers recorded. It does not show that a person died, moved or was registered twice. "Absent" rests on the least, since it can mean only that nobody was home.
Names deleted after the draft
Bihar ran its revision in 2025 in two phases. Phase 1 is the names left off the draft. Phase 2 is the names deleted after the draft, which carry no reason. The Bihar pages count both, per 100 electors on Bihar's 2025 roll, and call the two together the names left off or deleted. Hyderabad's five Old City seats are counted from the lists of names left off the draft in each polling part.
In every state, the names deleted after the draft come from the objections upheld and the notices heard. They are a few in every hundred, so the site gives them per 1,000 electors on the draft.
The fall in the roll
Where a state published its rolls and no count of the names left off below the state, the site subtracts one published roll from an earlier one. That is the fall in the roll. It is a different count from the names left off, because between the two dates the roll also lost its ordinary deaths and moves and gained new voters. A fall can be smaller than the names left off, and a roll can even rise. West Bengal, Kerala, Rajasthan, Manipur and Odisha's districts are read this way, and each page names its two rolls.
The change after the draft
From the draft to the final roll, names are added and deleted. Most states published only the difference, the net change. A rise after the draft counts new voters along with any names put back, so the site calls it the most that could have been restored, never the names restored. Chhattisgarh and Mizoram are measured by this rise, because most of their districts grew after the draft. Assam is measured by the fall from its draft to its final roll, because its Special Revision published no count of names left off.
Notices
A notice goes to an elector who is on the draft roll but whose record the officer has to check. Two lists produce them. The no-mapping list holds electors who could not be linked to the roll of the last intensive revision, which in most states was held in the early 2000s. The logical discrepancy list holds electors whose record the Commission's software flagged for a mismatch, such as a name that differs from a parent's record, or ages and family sizes that the software tests. The Commission has not published the list of tests. An elector can be on both lists, so the two can add up to more than the total. The counts by state are on How the SIR Was Run.
Per 100 electors, and why states are not ranked
Every rate names what it is divided by, which may be the roll before the revision, Bihar's 2025 roll, an earlier published roll or the draft. Two rates with different counts or different bases measure different things, so the site never ranks one state's places against another's. Inside a state, every district or constituency is set against the others in that state's own measure.
The table below gives the measure each state's constituency figures use.
Uttar Pradesh, Karnataka, Andhra Pradesh, Chhattisgarh, Mizoram and Telangana published district tables only, and their district pages use the names left off the draft or, in Chhattisgarh and Mizoram, the rise after it. The other states and territories published state totals.
Women's share
Where a state split its names by sex, the site sets women's share of the names left off against women's share of the roll. A larger share among the names left off means women were left off more often than men. The tables do not say why. Where only the draft was split by sex, the page says the share of the names left off cannot be counted.
Religion and caste
No official table gives religion or caste. On the Bihar and Hyderabad pages they are guessed from names, and the result is given as a range, from the names that could be classified to every name that might belong. A figure from a news report that guessed religion from names is marked as the report's.
Against the winning margin
The winning margin is the winner's votes less the runner-up's at the last election. A seat where more names were left off than the margin is one where the names left off were large enough to have decided the result. That does not show they did, because the people left off would not all have voted, or voted the same way. Where a state's names left off are known only for the state or the district, the site spreads them over its seats by electors, which gives how many seats could be over the margin and never which ones.
Typical district, ranks and links
The typical district is the middle one when a state's districts are put in order. A rank correlation, from -1 to 1, says how far two things rise together across a state's districts, where 0 means unrelated. With few districts a correlation can arise by chance, and the site marks it "could be chance" unless it is larger than 1.96 divided by the square root of one less than the number of districts. Circumstances such as schooling, cooking fuel and sanitation move together, so none of them is named as a cause.
Sources, the press and rounding
Most figures come from the tables of the Chief Electoral Officers and the Election Commission. Where a table reached the site only through a newspaper, as a printed table or a photograph of one, the page says so, and a figure printed in lakh is marked as rounded. Counts are written with Indian grouping. A lakh is 1,00,000 and a crore is 100 lakh.
No name, EPIC number or address appears anywhere on the site. Every figure is a count.
