In this recent study we would like to show how migration affects in Borsod-Abaúj-Zemplén County, which components it has, what differences are there between gross and net emigrational inclination, what measures have been done by the ones who are determined to leave Hungary in expectations of a foreign job. A 375-element-sample was taken and had been appraised in order to measure the net emigration, the emigrational network and so the emigrational shell.
