Projections of future population changes are based primarily on trends observed in levels of births, deaths and migrations in local authorities over the 5 years leading to 2014, and these are used to predict population change until 2039.
Current population projections for NHS Coastal West Sussex CCG are estimating an overall population increase of 8.3% over the next ten years and a 16.2% increase over the next two decades. Higher percentage increases are expected in older age groups, specifically persons aged 65-84 years (+20.0% by 2026, and +41.4% by 2036) and aged 85 years or above (+31.0% by 2026, and +108.4% by 2036). The population of those aged 85 or above is expected to more than double by 2036 in NHS Coastal West Sussex.
Note. The projections included in this report show projected change to 2036. These are subnational population projections (SNPP) that were produced by the ONS in 2016, and are based on the 2014 mid-year population estimates. As a result, these estimates are based on the old CCG boundary where four lower-layer super output areas (LSOAs) were formerly assigned to Guildford and Waverley CCG. This is reflected in the difference between the total population size presented in the projection table below, and the mid-year estimates table, and equates to a deficit of around 7,000 residents. As such, the projections for Coastal West Sussex (particularly for later years) are likely to underestimate the projected population size of the CCG area when the new boundary is taken into account.
