Leicester statistics in the same format:
63.8 - White
3.07% - Black
29.9% - Asian
0.5% - Chinese
0.32% - Other race
2.32% - Mixed race
Now when I look around my office I would say that approx 25% of the staff are non-white, which roughly matches the population.
I would say this has been the case in every office I've worked in (the percentage roughly reflects the diversity of the location I mean, not the precise percentage shown above).
On the one hand I find the idea of affirmative action quite sinister - choosing a candidate because of the colour of their skin rather than because of their ability. However I find the idea of an all-white office in such an ethnically diverse area rather sinister as well - for exactly the same reason.
