If children are born in the UK they may accurately, for statistical purposes, be described as being born to foreign born parents or, in some cases, the children of forign nationals if their parents are not British citizens.
However it is simply illogical and misleading to include children of British citizens, who may themselves be born outside the UK, as 'foreign born' and just plays along with the BNP image of a non-British population of second or third generation descendants of immigrants.

As I stated earlier 'ghettoization' can be a very real problem as indeed the Spanish feel about the estimated 100,000+ UK ex pats who lead a very seperate unintegrated lifestyle from their host communities.
In an English town I once worked in all the mayors for over 20 years had had Irish family names!

Some of the reasons for this are too obvious to go into any detail but would include the need for family and community support networks, availability of accomodation coupled with 'white flight' etc

Some of the 'solutions' are not so obvious but we have a thread that is open for discussion!
