Welsh is the main language in the village. In 1991, 83% of residents spoke Welsh. This figure has since declined with the 2011 census indicating 73% of the population as Welsh speakers, with 82% having skills in Welsh The higher part of the village, which goes up towards the
Carneddau mountains, is considerably more English-speaking than the lower parts of the village. Most residents commute to work from the village, many to
Bangor. The main gathering points include the local pub (The Royal Oak or
Y Dderwen Frenhinol) and the local post office. Rachub is home to
Ysgol Llanllechid (the Welsh-language
primary school), and a chapel. Rachub is often considered to be a part of Bethesda rather than a separate entity. Villagers will variously say that they are from either Rachub, Llanllechid or Bethesda, depending on whichever one takes their fancy at the time. ==Notable residents==
