Carolling largely follows a bimodal distribution based on social class. It's still reasonably common among lower-working-class kids looking for a bit of extra pocket money before Christmas; for similar reasons, they're the last stalwarts of the penny-for-the-guy tradition. It's very common for those at the upper reaches of the middle class, who have a real penchant for old-fashioned community activities like choirs, fetes and street parties. It's all but dead for the majority in the middle.

Speaking more broadly, there has been an effort in many rural areas to maintain and revive particular local cultural traditions. Perhaps the most spectacular such tradition is the tar barrels in Ottery St Mary[1], but I'm also rather fond of the Royal Ashborne Shrovetide Football game[2] and the multitude of mumming and wassailing traditions[3].
