The aim of this health needs assessment is to identify the needs of the Gypsy, Traveller and Boater (GTB) communities in Wiltshire, to describe the current services and support in place to address these needs and to identify the gaps in service provision using evidence-based or best-practice approaches. This report, in conjunction with further input from the Traveller Reference Group (TRG), will guide ongoing developments in reducing health inequalities and improving health outcomes for these communities.
