KARACHI: In the 2008 General Elections, the Sindh Assembly recorded a voter turnout of 44.5%, with 8.69 million votes cast out of 19.54 million registered voters. Sindh, Pakistan's second-most populous province, is a significant economic hub with Karachi as its capital. The province's electorate includes both urban centers like Karachi and Hyderabad, and rural areas with agrarian communities.

According to Free and Fair Election Network, the registered electorate in Sindh consisted of 10.92 million male voters and 8.62 million female voters, resulting in a gender registration gap of 2.30 million. The turnout of 44.5% in the provincial assembly elections reflects a variation observed across twelve elections, influenced by the urban-rural divide in political activity.

The election saw 182,208 rejected ballots, which constituted 2.1% of the total votes cast. Historically, the rejection rate has varied, with the lowest at 0.7% in 1990 and the highest at 4.1% in 2013 and 2018. The increase in rejection rates in recent elections may be attributed to changes in electoral processes and voter roll complexities.

Over the decades, Sindh's registered electorate has grown significantly from 5.3 million in 1970 to 27.0 million in 2024. Similarly, the number of votes cast for the Sindh Assembly increased from 3.1 million in 1970 to 11.7 million in 2024. The highest recorded turnout for the Sindh Assembly was 60.7% in 1988, while the lowest was 29% in 1997.
