Population change

Population change is due to two reasons. These are births and deaths (known as natural change), and migration.

Year on year, Kent has seen more births than deaths and more people moving in to Kent than leaving. The result has been steady population growth in the county. The overall effects are presented in 'What's causing Kent's population growth?' (PDF, 346.4 KB).

More information on natural change can be found in the births and deaths bulletin (PDF, 1.5 MB).

More information on migration can be found in the migration in Kent bulletin (PDF, 944.6 KB).

The NINOs in Kent bulletin (PDF, 704.1 KB) looks at the number of new National Insurance Numbers issued to overseas nationals. It shows the latest numbers and a time series of NINOs in Kent, including details of the countries they have come from.

Life expectancy in Kent for males and females at birth and at age 65 is available in our life expectancy bulletin (PDF, 3.2 MB).

Each year the Office for National Statistics (ONS) produces mid-year population estimates. These are calculated using the population count from the last available census as a base then adding the number of births and inward migrants and taking away the number of deaths and outward migrants.

The interactive population estimates toolkit (XLSM, 2.7 MB) provides access to population estimates by gender and single year of age for all 12 Kent local authority districts and Kent County as a whole back to 2003. This toolkit allows users to access population estimates for any chosen age group and compare up to three separate areas in Kent at the same time.

Further information about population change is available on the Office for National Statistics (ONS) website.
