When Alexei Kosygin resigned in 1980 Tikhonov, at the age of 75, was elected the new Chairman of the Council of Ministers. During his five-year term as premier Tikhonov refrained from reforming the Soviet economy, despite all statistics from that time showing the economy was stagnating. Tikhonov presented the Eleventh Five-Year Plan (1981–85) at the 26th Party Congress, and told the delegates that the state would allocate nine million rubles for mothers who were seeking parental leave. In his presentation to the congress, Tikhonov admitted that Soviet agriculture was not producing enough grain. Tikhonov called for an improvement in Soviet–US relations, but dismissed all speculations that the Soviet economy was in any sort of crisis. Despite this, Tikhonov admitted to economic "shortcomings" and acknowledged the ongoing "food problem"; other topics for discussion were the need to save energy resources, boost labour productivity and to improve the quality of Soviet produced goods. Early in his term, in January 1981, Tikhonov admitted that the government's demographic policy was one of the weakest areas of his cabinet. In reality, however, he along with many others, were beginning to worry that not enough Russians were being born. The Era of Stagnation reduced the birth rate, and increased the death rate of the Russian population.
