A tale of two boroughs: Italians landing in Kensington and Chelsea vs Tower Hamlets 2002 - 2014

In absolute terms, the number of Italians being issued their first national insurance number (NINo) in Kensington and Chelsea more than doubled between the 2002/03 and the 2013/14 fiscal years.
On the other hand, while up to and including the 2004/05 fiscal year the Italians starting their London working life were landing in Kensington and Chelsea in almost twice the number of those landing in the less affluent borough of Tower Hamlets, since then the latter has seen an Italian invasion: in 2013/14 the number of Italians starting their working life in UK moving to Tower Hamlets has increased more than fifteenfold!
The following chart graphically describes the relative comparison between the two boroughs: Italians are clearly flocking to Tower Hamlets.

While Tower Hamlets is less affluent than Kensington and Chelsea, its average income is still higher than the average income of more than half of Italy. Charts describing a very similar dynamics could be produced using Brent, Haringey or Lambeth in the place of Tower Hamlets, while the raise of Italian immigration to Newham or Waltham Forest appears to have picked up only in the last couple of years.
