Population estimates and projections

The Office for National Statistics (ONS) produces two main measures of population change: estimates and projections. The key difference between these is that estimates consider only past population size and structure whereas projections are concerned with future populations.

Mid-year population estimates for Arun

  • Produced annually, the latest being the mid-2016 population estimate which was published on 22nd June 2017. 
  • Arun’s population was estimated to be 156,997 of which 75,159 were male and 81,838 were female. 

A one page sheet provides the Mid-2016 population estimates (by single year of age and sex).pdf [pdf] 33KB.

Population projections for Arun

  • Subnational population projections provide a picture of the population as it may develop in future years, indicating the potential size and age-sex structure. They are not forecasts and do not attempt to predict the impact that future government policies, changing economic circumstances or other factors might have on demographic behaviour.
  • Long-term subnational population projections are an indication of the future trends in population over 25 years from the base year.  They are trend based projections, which means assumptions for future levels of births, deaths, and migration are based on observed levels mainly over the previous five years. They show what the population will be if recent trends continue.  For this reason the accuracy of the projections decreases with increased time from the base year (2014 for the latest projections released on 26th May 2016).
  • A three page sheet provides Projections by sex and 5 year age groups between 2014 and 2039 [pdf] 52KB
  • A one page sheet provides Projections by components of change (i.e. births, deaths, migration) between2014 and 2039.pdf [pdf] 36KB
  • Subnational population projections are produced biennially. The 2016 based projections for Arun are scheduled to be published in May 2018.


Ward, Super Output Area, and Parish information

Ward Profiles

Ward profiles provide social and economic data for each of Arun’s wards.  Each profile is compared against average Arun figures.  Prior to the May 2015 district election the Arun District comprised 26 wards served by 56 District Councillors.  Since that election the district has 23 wards served by 54 Councillors.

  • Detailed profiles for the 26 pre-May 2015 wards are available.
  • The Local Government Association produces Basic Facts about wards which take into account the recent boundary changes.  These use aggregated data from output areas to create 'best fit' wards and are available for each of the 23 new wards.

Lower Layer Super Output Area Profiles

Lower Layer Super Output Areas (LSOAs) are a sub-ward geography averaging approximately 1,500 people. Wards are divided into several LSOAs, with between 2 and 6 LSOAs per ward (based on the pre May 2015 wards).  Arun District has a total of 94 LSOAs.

Output Area Profiles

Output Areas (OAs) are a sub-LSOA geography averaging approximately 300 people.  LSOAs are divided into several OAs, with between 4 and 9 per LSOA.  Arun District has a total of 519 OAs.

Parish Profiles

Parish (community) profiles are structured around eight issues that have been identified as important for a sustainable community, these are: social and cultural; equity and prosperity; economy; housing and the built environment; transport and connectivity; services; environmental, and governance.  Community profiles for the 21 parishes that Arun is the planning authority for are shown below.  10 further parishes within the district (Findon, Slindon, Clapham, Patching, Poling, Warningcamp, Houghton, Burpham, Madehurst, and South Stoke) are handled by the South Downs National Park Authority.
