Components of population change

The charts in this section show the components of population change. The components are natural change (births and deaths); internal UK migration (people moving in and out of Buckinghamshire from other parts of the UK), and international migration.

The data from the Office for National Statistics (ONS) provides a rich picture of the components of population change in Buckinghamshire. The charts show the key drivers of population change in the county and cover the years 2011 to 2019 (the latest data available).


The drivers of change are births and deaths (natural change), internal UK migration, and international migration. Migration statistics are split into two components (national and international) to provide insight into the number of people who move into and out of the county from other parts of the UK or other countries of the world.

Births have outnumbered deaths every year since 2011 in Buckinghamshire. Subtracting the number of deaths from the number of births provides the figure for natural change. From 2011 until 2015 the natural change figure averaged 2,050 additional people per year. From 2015 to 2019 the average figure dropped to 1,330 people per year. The fall is because of an increasing number of deaths and a slight drop in the number of births. 

 

Net migration was a major driver of population change during the period 2011 to 2019. On average a net of 2,700 additional people arrived in the county each year. Internal migration is the biggest component of net migration with an average of 1,740 people moving to Buckinghamshire each year from other parts of the UK. International migration resulted in a net average increase of 960 extra people arriving in the county each year.
