> Moreover, the [Henley] report uses a far narrower definition of ‘millionaires’ that does not include all dollar millionaires like the standard definition (people with net worth of 1 million dollars or more), but rather only individuals with liquid assets worth 1 million dollars or more, who are thus richer and more mobile on average than a standardly defined millionaire. In the case of the UK, the ‘millionaires’ identified by the report represent just a fifth (20%) of the UK millionaire population. Even then, the report is based on a small sample from within these narrowly defined millionaires and the sample is skewed towards centi-millionaires and billionaires, who are also likely to be the most easily mobile.

Are "people with net worth of 1 million dollars or more" considered very wealthy in the U.K. these days? In the U.S. there are many many homeowners who are millionaires by this definition, and that's not a population that would be likely to have the means to buy their way into another country.

The UK government defines wealthy as £2 million, or an income of £200k a year or more over three years.

But also your average UK home isn't worth $1 million.The average house is £269k, so a house worth a million dollars is worth 3 average houses.
