Summary

  • The 2012 mid-year population estimate for West Sussex was 815,100
  • This was a 0.8% increase from the 2011 mid-year estimate, which is an increase of 6,200 people.
  • This is similar to the percentage change seen for the South East but slightly higher than the 0.7% change for England. There were 53.5million people in England in 2012, 53.1 million in 2011.
  • The number of older people continues to increase faster than the overall population change. Between 2011 and 2012, there was a 3.8% increase in older people aged 65 years and over, which is higher than the 0.9% increase in the 0-19 years age group and the 0.3% decrease in the 20-64 years age group.
  • The population increase in West Sussex was accounted for by natural change(600 more births than deaths) and more significantly, by inward migration of 5,600 people into the county.
  • Migration patterns show that there is more internal migration (from other areas in the UK) into the county than international migration. More than 90% of migration into the county was internal migration. This is seen for all districts apart for Crawley where net international migration was higher than net internal migration.
  • Adur, Arun and Crawley had the highest population increase between 2011 and 2012 while Chichester and Horsham had the lowest population increase (0.4% and 0.5% respectively).
  • Population increase in Adur, Arun and Chichester were caused entirely by inward migration as there were higher number of deaths than births in these districts.
