Labour migration has become a common occurrence in a world where the population driven by a variety of personal reasons, most often economic, decides on them.The Republic of Croatia is a country that is considered to be emigrant due to the traditional waves of emigration of its population.Thatprocess is particularly enhanced by the entry of Croatian into the European Union and the opening of the labour market of other countries for the Croatian labour force. The Government of the Republic of Croatia has recognized the problem of emigration, and ultimately tries to take concrete measures to reduce emigration.Due to a lack of Croatian economic development in contrast to Western European countries it is extremely difficult process.With the accession of Croatia to the European Union, the number of immigrants increased, but still less than the number of emigrants.This is also reflected by the negative migration balance achieved in each year through the observed period since Croatia's accession to the European Union.While the Croatian labour force decides mainly to emigrate to Western European countries, Croatia is not attractive to the inhabitants of those countries.ThirdWorld countries and returnee migration mainly form the immigration base of the Republic of Croatia.
