Population and migration statistics, 2011 to 2021

16 June 2023

Statistics Jersey are today releasing updated population and migration statistics for the period 2011 – 2021. 

These statistics have been produced using administrative data (data already held by Government of Jersey).  This new method has been developed to provide more accurate and granular information on population and migration in Jersey.

The administrative data method for estimating population and migration provides:

  • more accurate annual population estimates than previous methodology 
  • information on inward and outward migration flows, on a quarterly and annual basis
  • more granular breakdowns of population and migration estimates by age, sex, and housing and work status
  • Jersey’s population increased from 97,900 at the end of 2011 to 103,100 at the end of 2021.
  • More births than deaths were seen in each year from 2011 to 2021, though this natural change was seen to reduce over the decade from 330 in 2011, to 120 in 2021.
  • From 2011 to 2018 inclusive, Jersey had net inward migration, averaging 530 per year.
  • During the three years 2019 to 2021 inclusive, net migration was outwards (more people outwardly migrating than inwardly migrating), with an average of 180 people leaving each year, over and above those arriving. This was the period which included the events of the UK leaving the EU and the covid pandemic.

The administrative data methodology enables more granular reporting for the period from the beginning of 2017 to the end of 2021, including information on the size of migration flows, by housing and work status, as well as seasonal patterns in net migration. 

Full information on the methodology is provided in the separate report
