The crisis of 1930–1934 differs in many ways: the percentage of the population living with non-agricultural employment was reduced from 15.9% in 1930 to 15.4% in 1938. Albanian exports grew from 2 million gold francs to 12 million between 1923 and 1931, but fell back to 1923 levels within the next two years. A difficult situation occurred between 1935 and 1936 when the government was forced to distribute emergency food aid in poor areas. Places that sold Albanian goods placed tariffs on imports of cheese and butter. The crisis affected the livestock industry, which accounted for 70% of total national exports. Another significant impact was the establishment of the so-called "tax xhelepit", which applied to head/livestock. In 1933, the state cut the taxes by 50%.
