Croatia proper comprises several smaller regions of its own: the Croatian Littoral, Lika, Gorski Kotar, Međimurje, Podravina, Posavina, Kordun, Banovina, Prigorje, Turopolje, Moslavina, and Žumberak. The sociogeographical distinction between Central Croatia, the Croatian Littoral and Mountainous Croatia has become more pronounced over time, as the western, mountainous areas of Lika and Gorski Kotar suffered from population depletion during the 20th century, especially during World War II and the Croatian War of Independence. The 2001 census indicated a large proportion of elderly, when 31.5% of population of Lika was over 60 years of age. The Ogulin-Plaški Valley contains the largest settlement of the area, Ogulin, with a population of 8,216. The second-largest settlement in Mountainous Croatia, and the largest in Lika, is Gospić.
