20–44 years, 25% aged 45–64 years and 22% aged 65 years and over. The town had a high percentage of residents over 65, compared with the national average of 16%. As a seaside town, Herne Bay is a popular retirement destination; many modern retirement complexes are located near the seafront. The economic activity of residents aged 16–74 was 36% in full-time employment, 13% in part-time employment, 9% self-employed, 3% unemployed, 2% students with jobs, 3% students without jobs, 18% retired, 7% looking after home or family, 6% permanently sick or disabled and 2% economically inactive for other reasons. This was roughly in line with the national figures, except for the number of people in retirement. This figure nationally was significantly lower at 14%. Of the town's residents aged 16–74, 12% had a higher education qualification or the equivalent, compared with 20% nationwide. According to Office for National Statistics estimates, during the period of April 2001 to March 2002 the average gross weekly income of households in the Herne Bay area was £516 (£26,906 per year).

It is hoped this will attract new investment in tourism and business by the private sector, and lead to the regeneration of the town's economy.
