West Sussex is a large and diverse county covering an area of 769 square miles with over half the land designated as protected countryside. It has a high concentration of coastal communities, as well as extensive rural areas.
The population of West Sussex is approximately 882,700 (699,330 adults) which has increased by 9.4% over the last 10 years. This generally reflects increases at a national and regional level with the largest increase of over 20.8% in the 65+ age group. The population in West Sussex is projected to increase by 8% from 2018 to 2028 with larger increases in the 65+ age group (23%) and notably in the 85+ age group (28%).
Overall, in West Sussex, people enjoy a good quality of life with a relatively high life expectancy of 82.5 years when compared with England 81.4 years; life expectancy for men is 80.3 years and 83.9 years for women.
In 2018-20, the male healthy life expectancy was 63.8 years and the female 63.9 years, which is in line with the national level.
Health inequalities persist
The average life expectancy in West Sussex marks considerable inequality, and differences between areas and different groups within the population. Some neighbourhoods in Arun and Crawley rank amongst the 10% most deprived in England, and there remain considerable differences between the life expectancy of the wider population and people with mental health problems and those with disabilities, including learning disabilities.
People from lower income groups are more likely to be in poorer health, have a limiting long-term illness and lower life expectancy.
Men living in deprived areas have 7.6 fewer years in life expectancy and women have 6.4 years.
It is important to recognise that there are other groups in the population which are at higher risk of poorer health and wellbeing outcomes. These include:
- Carers (notably those caring for over 50+ per week)
- People living in poverty
- Homeless people
- Children in care or leaving care
- Military veterans (notably younger veterans leaving service early)
- Gypsy, traveller and show people
- Refugees, asylum seekers or undocumented, forced, smuggled or trafficked migrants
- People in detention
