4. Assesing London's international migration flows

This map indicates sources of international migration to London boroughs from 2004-2017. The migrations themselves are visualized as flow lines, while circle layers in each borough indicate the relative size of the total inflows to that borough in each year. Circle layers associated with each broad geographic region that migrants originate from also vary in size per year, and if clicked indicate the total numbers of people who left that region to move to London in the currently selected year. To visualize the flows into a borough, anywhere in the borough can be clicked to show the lines of migration in that year. The underlying migration data for this map was sourced from London Datastore.

The broad results of this map show that as a whole, and per most individual boroughs, total numbers and relative rates of migration have increased since 2004. While certain boroughs like Newham and Ealing have consistently large immigration flows from specific areas like South Asia, the two regions that have increased the most over time are the EU8 and EU2 countries. In particular, the EU2 countries of Bulgaria and Romania see a stark increase in migrants since their join to the European Union in 2007.
