The East Riding is characterised by a high employment rate and a relatively low unemployment level. The overall unemployment rate is 4.3%, which is 1.2 percentage points lower than the national average. However, there are unemployment hotspots in Bridlington, Goole and Withernsea. Unemployment levels tend to fluctuate over the course of the year with lower levels during the summer months due to increased employment in the tourism and food production sectors. A major year-round employer in the East Riding is the Defence School of Transport at RAF Leconfield, which trains 14,000 personnel from the Army, the Royal Air Force and the Royal Marines each year and provides more than 1,000 civilian jobs.
