While there's definitely something to be said for ignoring the ridiculous extremes that a world of billions of people can throw up, there's still some much less dramatic effects in our daily lives.

For example, at the big company I worked for in the UK if you were to look at our marketing material, documentation and in-app images you'd be forgiven for thinking that the UK was 30% black and 20% South Asian. (East Asians were comparatively neglected, being about as common as white men)
