British Future publish daft graphs on British identity
The new think tank British Future have released some Ipsos-Mori polling on identity in conjunction with the Observer.
It finds that the sense of belonging to England (in England) is weaker than the sense of belonging to Britain (in Britain) among immigrants.

With the reverse being true for those born in Britain.

They've chosen a peculiar way to publish the results. Why not publish a like for like analysis? One has to wonder if the sample size wasn't big enough to publish separate results for Scotland and Wales (Northern Ireland appears to have been omitted), or whether they deliberately chose not to make public that data. It would be interesting to see the results for each of the home nations alone, hopefully that information will be made available on the British Future website.
A previous poll on belonging conducted by the Ministry of Justice found that a sense of belonging to England was higher than the sense of belonging to Britain amongst both whites and BMEs.
UPDATE: The British Future report, due to be published on Monday, will contain polling data on support for an English parliament. I will publish the results here.
