combination of a market economy with a comprehensive social security system, providing citizens with universal health care, free education, and one of the longest paid parental leaves in the OECD. Slovakia is a member of the European Union, the Eurozone, the Schengen Area, the United Nations, NATO, CERN, the OECD, the WTO, the Council of Europe, the Visegrád Group, and the OSCE. Slovakia is also home to eight UNESCO World Heritage Sites. The world's largest per-capita car producer, Slovakia manufactured a total of 1.1 million cars in 2019, representing 43% of its total industrial output. Etymology Slovakia's name in theory means the "Land of the Slavs" (Slovensko in Slovak stemming from the older form Sloven/Slovienin). As such, it is a cognate of the words Slovenia and Slavonia. In medieval Latin, German, and even some Slavic sources, the same name has often been used for Slovaks, Slovenes, Slavonians, and Slavs in general. According to one of the theories, a new form of national name formed for the ancestors of the Slovaks between the 13th and 14th century, possibly due to foreign influence; the Czech word Slovák (in medieval sources from 1291 onward). This form slowly replaced the name for the male members of the community, but the female name (Slovenka), reference to the lands inhabited (Slovensko) and the name of the language (slovenčina) all remained the same, with their base in the older form (compare to Slovenian counterparts). Most foreign translations tend to stem from this newer form (Slovakia in English, Slowakei in German, Slovaquie in French, etc.). In medieval Latin sources, terms Slavus, Slavonia, or Slavorum (and more variants, from as early as 1029) have been used. In German sources, names for the Slovak lands were Windenland or Windische Lande (early 15th century), with the forms "Slovakia" and "Schlowakei" starting to appear in the 16th century. The present Slovak form Slovensko is first attested in the year 1675. History The oldest surviving human artefacts from Slovakia are found near Nové Mesto nad Váhom and are dated at 270,000 BCE, in the Early Paleolithic era. These ancient tools, made by the Clactonian technique, bear witness to the ancient habitation of Slovakia. Other stone tools from the Middle Paleolithic era (200,000–80,000 BCE) come from the Prévôt (Prepoštská) cave in Bojnice and from other nearby sites. The most important discovery from that era is a Neanderthal cranium (c. 200,000 BCE), discovered near Gánovce,
