Is there a website where you check which Polish family names are popular in which region

In Belgium we have such a website, very informative and entertaining as well. Does there exist such a site in Poland as well?

We have been using such site for a long time in PF, particularly in the thread "The meaning of your Polish last name" (3021 posts so far).

It is based on the same engine as many other sites elsewhere: Germany, Austria, Switzerland, etc. You have to watch one thing: it does not recognize that -SKI and -SKA are the same names, so you have to test it twice to get totat statistics. It is also very sensitive to diacritic signs, so make sure to put them wherever needed.

Edited:
I believe that data collection in Poland is based on PESEL numbers; in Germany of phone lines.

Thanks a lot!

I am using this site:
moikrewni.pl/mapa/

In the empty field put a desired surname and click the 'szukaj' button.
