You will hear all kinds of people in authority say that immigration, or population growth, is causing people to turn into racists and vote BNP, either just because (the rightwing version) or because of "pressure" on public services (the Decent Left version).Therefore, they usually say, we need a stingier immigration policy. If you're reading this, you probably think this is crap. But now, I can prove this scientifically. Thanks to the leaked BNP membership list, we can empirically measure how many people are active racists, active and committed enough that they joined a political party and paid a subscription. Using the data by county, I established a table that matched the UK regions.
Now, if immigration or population growth really is causing people to go fascist, we'd expect to find a correlation between population growth and BNP membership. Or, perhaps, we might find that places that are losing population are economically depressed and hence susceptible. A further detail might be changes in population density; becoming more urban might lead to a perception of being "swamped", or becoming more rural/exurban might lead to one of isolation. So I drew up a table of population growth from 1991 to 2006, change in density for the same period, and BNP members per 100 citizens.
Here are the results.
Population growth is on the Y axis, bigots on the X axis; the size of each dot represents the change in density. There is no correlation whatsoever. Anyone who tells you this story is talking nonsense.
