Ahead of the 2014 general election, the Election Commission renumbered the seat for Sandwip Upazila from Chittagong-16 to Chittagong-3, bumping up by one the suffix of the former constituency of that name and the higher numbered constituencies in the district. Thus Chittagong-11 covers the area previously covered by Chittagong-10. Previously Chittagong-11 encompassed all but five union parishads of Patiya Upazila: Bara Uthan, Char Lakshya, Char Patharghata, Juldha, and Sikalbaha .[5][2]
