Administrative districts
At the time of the 2010 Census the Regency comprised eight districts (kecamatan), but subsequently a ninth district - Batu Putih - was created from the southwest part of Gunung Terang District. The first three districts listed below lie south of the Tulang Bawang River (although Tulang Bawang Udik District straddles the river in the west), while the other six districts lie north of the river. The districts are listed below with their areas and their populations at the 2010 Census and the 2020 Census, together with the official estimates as at mid 2023. The table also includes the locations of the district administrative centres, the number of administrative villages in each district (totalling 93 rural desa and 3 urban kelurahan), and its post code.
