The Second Five-Year Plan encountered difficulties, and the government replaced it with the Seven-Year Plan (1959–65). The new plan aimed at achieving West Germany's per capita production by the end of 1961, set higher production quotas, and called for an 85% increase in labor productivity. Emigration again increased, totaling 143,000 in 1959 and 199,000 in 1960. The majority of the emigrants were white collar workers, and 50% were under 25 years of age. The labor drain exceeded a total of 2.5 million citizens between 1949 and 1961.
