Buan is located in the south-western central part of Gwynedd on the Llŷn Peninsula, in North West Wales, and includes the villages of Boduan and Rhydyclafdy. The landscape is dominated by farms and woodland.^[3] According to the 2011 census, the community of Buan had a population of 484 people (250 males and 234 females). In addition, there are 195 households in the community with a population density of 0.1 per hectare.^[4] Buan is situated near the Corn Bodvean hill, and its nearest town is Nefyn which is located approximately 1-mile (1.6 km) south of the community.^[5] Christianity was the majority religion in the area with two people stating they followed other religions.^[6] Of Buan's 484 residents, 84.1% described their health as either "good" or "very good", and of those aged between 16 and over, 18.8% had no academic qualifications or one GCSE, lower than the figures for all of Gwynedd (23.2%) and Wales (25.9%).^[4]

The community includes the Marilyn and hill fort of Garn Boduan.

In local government Buan is governed by Gwynedd Council, and is in the Efailnewydd/Buan ward, which is part of the Dwyfor electoral district.^[7] At the national level Buan is in the Welsh parliamentary constituency of Dwyfor Meirionnydd, for which Liz Saville-Roberts (Plaid Cymru) has been MP since 2015.^[8][9] In the general election of 2015 Saville-Roberts won 11,790 votes (40.9%), giving her a majority of 5,261; the Conservative Party won 6,550 (22.7%) and the Labour Party won 3,904 votes (13.5%), while the United Kingdom Independence Party took 3,126 votes (10.8%).

Ysgol Rhydyclafdy School was the only primary school in the community and closed in 2008 due to a falling number in pupils and as part of a programme that saw two additional schools being closed on the Llŷn Peninsula. Gwynedd Council allowed the building to be reopened as a nursery with community facilities two years later.^[11]

Buan contains 34 Grade II listed buildings, in addition to two Grade II* listed buildings.^[12] The former church of the same name, St Buan, was built in 1765, and is reminiscent of the Romanesque style in design. The church was later deconsecrated and sold in 2004.^[13]
