A total of 17.49 million votes were polled for the National Assembly in the General Elections, 1977, out of 30.48 million registered voters, recording a turnout of 57.4%.
The 1977 general elections were held on 7 March 1977 under the government of Prime Minister Zulfikar Ali Bhutto. Nine opposition parties contested under the banner of the Pakistan National Alliance (PNA). The election results — which returned the ruling Pakistan Peoples Party with a landslide majority — were disputed by the PNA, which alleged large-scale rigging. The political crisis that followed culminated in General Muhammad Zia-ul-Haq’s military coup on 5 July 1977, which suspended the Constitution and imposed martial law. Provincial assembly elections were held separately on 10 March 1977.
Of the 30.48 million registered voters, 16.74 million — 54.9% — were male and 13.72 million — 45.0% — were female. The gender gap in voter registration stood at 3.01 million, representing 9.9% of the total registered electorate.
At the National Assembly level, 17.49 million votes were polled against a registered electorate of 30.48 million, producing an overall turnout of 57.4%. This figure reflects votes cast across all National Assembly constituencies in the four provinces, and — from 2002 onwards — the Federally Administered Tribal Areas (FATA), which were subsequently merged into Khyber Pakhtunkhwa through the Twenty-Fifth Constitutional Amendment in 2018.
Gender-disaggregated data on votes polled are not available for the 1977 elections. The systematic disaggregation of votes polled by sex was not incorporated into election administration and result-reporting frameworks prior to the 2018 elections.
Of the votes polled at the National Assembly level, 377,240 ballots — 2.2% of total votes cast — were declared rejected or invalid. Rejected ballots include votes cast on incorrect ballot papers, those on which no mark was made, those bearing marks on multiple candidates, and those bearing marks that could not be attributed to a valid candidate. The rejection rate is a measure of the quality of voter instruction and the accessibility of the ballot design across the electorate.
Across all five assembly elections conducted concurrently in 1977, Punjab recorded the highest absolute number of votes polled, consistent with the province’s share of the national registered electorate. Khyber Pakhtunkhwa and Balochistan returned lower absolute polling figures, in proportion to their smaller registered electorates.
FAFEN’s analysis of Pakistan’s twelve general elections between 1970 and 2024 situates the 1977 National Assembly turnout of 57.4% within the broader trend of participation rates. The highest recorded National Assembly turnout across this period was 54.9% in 2013. The lowest was 34.8% in 1997.
