Economic growth of the Soviet Union in select periods 1966-1985

In each half-decade between the mid-1960s to the mid-1980s, there was a consistent decline in the growth rate of the Soviet Union's national income, industrial output, and agricultural production. In the early 1980s, national income and industrial output growth dropped below half of their respective rates in the late 1960s, while agricultural output fell to almost a quarter of its previous level.
