Yugoslavia took on a number of International Monetary Fund (IMF) loans and subsequently fell into heavy debt. By 1981, it had incurred $18.9 billion in foreign debt. In fact Yugoslavia's debt was just 20.11% of GDP in 1971, which is, when compared with UK (67.95%), USA (46.64%), Germany (17.87%), Italy (41.46%), a comparatively low rate. However, Yugoslavia's main concern was unemployment. In 1980 the unemployment rate was at 13.8%, not counting around 1 million workers employed abroad. Deteriorating living conditions during the 1980s caused the Yugoslavian unemployment rate to reach 17 percent, while another 20 percent were underemployed. 60% of the unemployed were under the age of 25.
