Miss. Code Ann. § 13-5-85

In Harrison County, a county having two judicial districts, the law in relation to the selection and liability to jury service of grand and petit juries shall be applicable to each of the two judicial districts of the county in the same manner as if each district were a separate county, so far as the same may be made to apply. No person shall be made to serve as a grand or petit juror except in the district in which he resides. Lists of persons subject and liable to jury duty shall be made and grand and petit jurors shall be selected and empaneled in each of said districts in the same manner as if each were a separate county, except in such cases where it is otherwise provided by law.
