The constituency was created for the 2010 general election following a review of parliamentary representation in Cornwall by the Boundary Commission, which increased the number of seats in the county from five to six. It replaces parts of the former Truro and St Austell and Falmouth and Camborne seats. ;Political history The result was a very marginal one in 2010, with the previous results in either predecessor seat also closely fought between the Liberal Democrats and the Conservatives. In the 2017 general election, the constituency was held by the Conservative, although the constituency experienced a 22.5% surge in the Labour vote - an 11.4% swing that nearly broke the Tories' seven-year hold on the seat. The 37.7% of the vote in Truro and Falmouth achieved by Labour marked their highest share of the vote in a seat incorporating Truro in 47 years.
Boundaries
The former District of Carrick wards of Arwenack, Boscawen, Boslowick, Carland, Feock and Kea, Kenwyn and Chacewater, Moresk, Mylor, Newlyn and Goonhavern, Penryn, Penwerris, Perranporth, Probus, Roseland, St Agnes, Tregolls, Trehaverne and Gloweth, and Trescobeas. The Truro and Falmouth constituency has the same boundaries as the former district of Carrick, with the exception of the ward of Mount Hawke, which is part of the Camborne and Redruth seat. The main settlements in the constituency are the city of Truro and the town of Falmouth, after which it is named. Other settlements include Penryn, Perranporth, St Agnes and St Mawes.
The constituency has visitor attractions spanning diametrically opposite coasts, including Porthtowan and Perranporth, noted for beaches. Falmouth abounds with restaurants, places to stay, as well as sailing and motor-yacht facilities. However, industries and businesses are not dominated by the arts or leisure and chiefly rely on maritime maintenance, hospitality, tourism, retail, distribution, and agriculture. In November 2012, unemployed people and registered jobseekers were lower than the national average of 3.8%, at 3.0% of the population based on a statistical compilation by The Guardian.
