About this data
Source: Election Commission of India, statistical reports for the 1967 Lok Sabha election (detailed results, list of winners, list of parties). Vote shares are of valid votes, excluding NOTA, as ECI reports them. Turnout here is votes counted (including NOTA) divided by electors, so it runs slightly below ECI's official figure, which also counts rejected votes.
Held before Meghalaya and Mizoram became separate: the Assam seats include theirs.
Constituencies of today's Telangana (15), Jharkhand (13), Chhattisgarh (10), Uttarakhand (5) are placed there by name; at the time they were part of Andhra Pradesh, Bihar, Madhya Pradesh, Uttar Pradesh, and a few boundaries straddled the present state lines.
Turnout is not shown: the report in ECI's PDF does not give the electorate seat by seat.
5 seats were won unopposed, so no poll was held there.
Map boundaries are approximate and for illustration.
