Most of the rivers stem in the Slovak mountains. Some only pass through and the others make a natural border with surrounding countries (more than 620 kilometres (385 mi)). For example, the Dunajec (17 kilometres (11 mi)) to the north, the Danube (172 kilometres (107 mi)) to the south or the Morava (119 kilometres (74 mi)) to the West. The total length of the rivers on Slovak territory is 49,774 kilometres (30,928 mi).
The longest river in Slovakia is the Vh (403 kilometres (250 mi)), the shortest is the ierna voda. Other important and large rivers are the Myjava, the Nitra (197 kilometres (122 mi)), the Orava, the Hron (298 kilometres (185 mi)), the Hornd (193 kilometres (120 mi)), the Slan (110 kilometres (68 mi)), the Ipe (232 kilometres (144 mi), forming the border with Hungary), the Bodrog, the Laborec, the Latorica and the Ondava.
The biggest volume of discharge in Slovak rivers is during spring, when the snow melts from the mountains. The only exception is the Danube, whose discharge is the greatest during summer when the snow melts in the Alps. The Danube is the largest river that flows through Slovakia.
The Armed Forces of the Slovak Republic number 14,000 uniformed personnel. Slovakia joined NATO in March 2004. The country has been an active participant in US- and NATO-led military actions. There is a joint Czech-Slovak peacekeeping force in Kosovo. From 2006 the army transformed into a fully professional organisation and compulsory military service was abolished.
Slovak Ground Forces are made up of two active mechanised infantry brigades. The Air and Air Defence Forces comprise one wing of fighters, one wing of utility helicopters, and one SAM brigade. Training and support forces comprise a National Support Element (Multifunctional Battalion, Transport Battalion, Repair Battalion), a garrison force of the capital city Bratislava, as well as a training battalion, and various logistics and communication and information bases. Miscellaneous forces under the direct command of the General Staff include the 5th Special Forces Regiment.
According to the 2011 census, the majority of the inhabitants of Slovakia are Slovaks (80.7%). Hungarians are the largest ethnic minority (8.5%). Other ethnic groups include Roma (2%), Czechs (0.6%), Rusyns (0.6%) and others or unspecified (7.6%). Unofficial estimates on the Roma population are much higher, around 5.6%.
In 2007 Slovakia was estimated to have a total fertility rate of 1.33 (i.e., the average woman will have 1.33 children in her lifetime), which is significantly below the replacement level and is one of the lowest rates among EU countries.
The largest waves of Slovak emigration occurred in the 19th and early 20th centuries. In the 1990 US census, 1.8 million people self-identified as having Slovak ancestry.
