Conversely, the area is also seeing the biggest decreases of population with rocketing internal migration to other areas - mainly the South East.
Data obtained by our Data Processing Unit has revealed the following shocking statistics of West London boroughs
- Hammersmith and Fulham, with an decrease of 0.65% in a year, or 1,165 fewer people, and Kensington and Chelsea, with an decrease of 0.22% in a year, or 336 fewer people, were among the fastest shrinking parts of the UK
- But Haringey, Hounslow, Ealing and Brent have seen some of the biggest growth due to having a higher birth rate than death rates.
- Brent and Hounslow also feature in the top 20 for high growth due to international migration
- Westminster has seen the biggest fall in population due to internal migration (people heading for other parts of the UK), with 6,338 more people leaving than arriving pushing the population down 2.8%.
- However, Westminster has also seen the biggest increase in population due to international migration, with 7,546 more people arriving than leaving increasing the population by 3.37%
However, an overall snapshot reveals that all parts of West London are in the top 25 of areas with the biggest falls in population due to internal migration, as more people head to different parts of the UK (or London and the South East) than arrive.
