Miss. Code Ann. § 19-3-1

Each county shall be divided into five (5) districts, with due regard to equality of population and convenience of situation for the election of members of the boards of supervisors, but the districts as now existing shall continue until changed. The qualified electors of each district shall elect, at the next general election, and every four (4) years thereafter, in their districts one (1) member of the board of supervisors. Subject to the provisions of Section 23-15-285, the board, by a three-fifths (3/5) vote of all members elected, may change the districts, the boundaries to be entered at large in the minutes of the proceedings of the board. Provided, however, that such changed boundaries shall in as far as possible conform as to natural, visible artificial boundaries, such as streets, highways, railroads, rivers, lakes, bayous or other obvious lines of demarcation, except county lines and municipal corporate limits.
