Population estimates

Estimates of the population by age and sex are provided for a range of geographies (e.g. output area, ward, district, CCG, county, region, and country). These are usually updated in June each year by the Office for National Statistics for the previous year (e.g. mid-2015 estimates were released in June 2016), with sub-national population estimates released later in the year.

These estimates have been collated by the Public Health and Social Research Unit for the geographies within West Sussex.

In 2015, 836,300 people were estimated to be resident in West Sussex.

This was nearly 8,000 more than in 2014, an increase of approximately 1%.

In 2015 there were 8,882 births, 9,385 deaths. Net internal migration (from/to elsewhere in the UK) was 5,541; net international migration was 2,440. This means that population increase resulted from, in the main, net internal migration.

Of the quinary age groups, the largest year‐on‐year change was in the 70‐74 years age group, where there were 1,751 more people than 2014; an increase of 4.3%

Each year the ONS release an estimate of the resident population in England and Wales.

Data are released once a year, are provided by gender and individual age group and information is also released on the “components of change”, i.e. births, deaths and migration.

The 2012 Mid-year population estimate for West Sussex was 815,100. This is a 0.8% increase from the previous year, caused by inward migration and to some extent a higher number of births than deaths.
