The National Caravan Council estimates that the caravan industry which includes motorhomes, touring caravans (caravans designed to be hitched to a car and towed to a site) and static caravans and mobile homes (caravans designed to be transported to a permanent site, where they are anchored to the ground) is now worth over £1bn (€1.5bn/US$1.7bn) to the British economy alone with the manufacture of caravans worth in excess of £650m (€975bn/US$1.1bn). The growth in popularity of caravanning has been enhanced by improvements in caravan quality and caravan site facilities, making caravan holidays possible at any time of the year.
