A kárpátaljai magyarok munkavállalói migrációja
The political and economic crisis of recent years has intensified the migrational activity from Ukraine to European countries with higher standards of living. Among the Transcarpathian Hungarians there are especially intensive migration processes for employment and other purposes, which was facilitated by owning Hungarian language skills on the one hand and possibility of obtaining Hungarian citizenship on the other. However, the number of Transcarpathian hungarians affected by migration, as well as the nature, duration and purpose of their migration, have not yet been investigated quantitatively. Our paper attempts to answer the above questions by evaluating the results of a questionnaire survey
A születésszámok alakulása Kárpátalján térben és időben
Transcarpathia is a fresh splash of color on the background of the low values of the regional birth rates, which highly stands out in terms of natality from surrounding county-level administrative units: the 14,8%o average registered here, exceed in 2- 5%o the corresponding indicators of neighboring regions. The article presents the long-term changes in the birth rate in the county in the last decades and mentions year-wise changes as well. The work analyzes the possible factors of temporal changes in birth rates. Hereinafter, the main aspects of the spatial distribution of natality were reviewed, mentioning the possible causes. The article attempts to estimate the birth rates regarding Hungarians, Ukrainians and Romanians in Transcarpathia on the basis of available indirect sources. Finally, according to the birth rate, with the help of cluster analysis the regionalization of Transcarpathia was performed. A szĂĽletĂ©si mutatĂłk kedvezĹ‘tlen nagytĂ©rsĂ©gi Ă©rtĂ©kei hátterĂ©n ĂĽde szĂnfoltot jelent Kárpátalja, amely a környezĹ‘ megyei szintű közigazgatási egysĂ©gek közĂĽl magasan kiemelkedik a natalitás tekintetĂ©ben: az itt regisztrált 14,8%o-es átlag 2-5%o-kel haladja meg a szomszĂ©dos rĂ©giĂłk megfelelĹ‘ mutatĂłit. A cikk bemutatja a szĂĽletĂ©sszámok hosszĂş távĂş változását a megyĂ©ben az elmĂşlt Ă©vtizedekben, valamint kitĂ©r azok Ă©vi járására is. A munka elemzi a szĂĽletĂ©si mutatĂłk idĹ‘beli változásainak lehetsĂ©ges tĂ©nyezĹ‘it. A továbbiakban a natalitás tĂ©rbeli eloszlásának fontosabb aspektusai kerĂĽltek áttekintĂ©sre, ezĂşttal is megemlĂtve a szĂłba jöhetĹ‘ okokat. A cikk az elĂ©rhetĹ‘ közvetett források alapján kĂsĂ©rletet tesz a szĂĽletĂ©si mutatĂłk becslĂ©sĂ©re a kárpátaljai magyarok, valamint ukránok Ă©s románok vonatkozásában. VĂ©gĂĽl a szĂĽletĂ©si ráta alapján clusteranalizis segĂtsĂ©gĂ©vel elvĂ©geztĂĽk Kárpátalja regionalizálását
