This is an interactive guide and tool for exploring some of the origin-destination data published for Census 2021.

Origin-destination data show the movement of people from one location to another, such as migration and commuting patterns. It is sometimes known as "flow data".

!

The coronavirus (COVID-19) pandemic strongly affected patterns of population movement. Census day was 21 March 2021, when lockdown restrictions were in force in the UK.

Using the tool

Choose between visualised flows for:

  • Migration flows - Movement from address 12 months prior to census day
  • Workplace flows - Usual residence and place of work

You can also switch direction to see aggregated movements to and from an area.

The tool is also embeddable for use in external websites. A link is provided within the guide article.
