Sailing is the local economy, not a sideline. The town is one of Britain's leading yachting centres with four clubs, the Royal Corinthian Yacht Club, Royal Burnham Yacht Club, Crouch Yacht Club and Burnham Sailing Club, plus Burnham Yacht Harbour. Burnham Week, an annual regatta, has run since 1893 and falls in the last week of August, dominating late-summer trade.
The High Street has retained its character and is largely independent, cafés, restaurants and small shops rather than chains. A small market runs on the High Street on Tuesdays, with a farmers' and artisan market on the third Sunday of the month.
Burnham was historically a fishing port known for its oyster beds; today marine trades, boatyards, chandlery and hospitality serving the sailing crowd are the recognisable business clusters.
It is the principal settlement of the Dengie peninsula, so it serves a wide rural catchment with relatively little competing retail nearby.
Burnham-on-Crouch had a recorded population of about 8,852 at the 2021 census.
