query: What were the boundaries of the Ceredigion constituency until 1983?
answer: Until 1983, the boundaries of the Ceredigion constituency (formerly Cardiganshire) remained virtually unchanged since its creation in 1536.  Before 1885, it comprised a county constituency covering rural areas and a borough constituency encompassing several towns (Cardigan, Aberystwyth, Lampeter, and Adpar). In 1885, the borough constituency was abolished and its towns were incorporated into the county constituency.
