Poles seems to me among the most 'middle coloured hairs' in Europe; but they present a very broad specter of colours from the flaxen blond to jet black (rare this last one); when I group the light hues, flaxen whitish blond to very dark blond-very light brown, I find around 32% of light - from jet black to blackish very dark brown, i find around 16%, all that as national mean because I have too few by regions; so not very light, not very dark, rather mean with every kind of brown hair, spite light dominates dark; close to the English or Belgish means but in Poland the very light blond are more numerous, their dark blond are often greyish, and the dark golden blond are rarest than in Western Europe, fact common to Baltic, Finnish and Slavic countries - and they have few red or neatly reddish hairs (1,2% only), even less than Hungarians or Czechs, except in the mountainous regions of South (here I base myself on books) -
the North is a bit lightest, the most beteen Sczeczin and Gdansk, but it never rise to the %'s of fair hairs of Northern Germany or of the Finno-Scandinavian countries-
in France too we had the stereotype of the blond 'Polak'; maybe it's explained by the fact a lot of migrants inFrance came from northern regions of Poland, at the time the poorest, less industrialized than today? Only a supposition. Could someone answer me here?
we know that concerning emigration, the geographic origin of migrants country by country is not level with the national mean, for regional economic discrepancies (irishmen of Connaught orWest Munster, Swedes of Skane, Italians of South Italy...)
