Recent Population Trends

Analysis of longer term demographic change in Swansea using the mid-year estimates of population.

Between each decennial Census, the Office for National Statistics (ONS) publish annual population estimates every June, relating to the previous year's mid-point.  The estimates are calculated by using the Census as a benchmark, and combining subsequent annual birth and death registrations data with estimates of internal (within UK) and international migration flows.

From 2001 to 2019, the estimates showed successive annual increases in Swansea's population.  However, the rate of population growth has slowed in recent years, with a small decrease recorded between 2019 and 2020.  Between 2015 and 2020, the estimated population of Swansea has increased by 4,200 or 1.8% (from 242,300 to 246,500), an average increase of approximately 850 people (0.4%) per year. 

briefing note (PDF) [1MB] is available which explores long-term population change in Swansea in more detail, focusing on recent trends in the latest five years (2015 to 2020). 

Further information on the latest population estimates is included in the Population page.  The population web page also includes links to additional local information on population and demography, including: population estimates for small areas in Swansea; population density; population characteristics; previous Census statistics; household estimates; and the latest official population and household projections.
