Defense spending, as a share of total expenditures, has increased significantly since the 1960s: from 3.7% in 1959 to 19% in 1960, and, after averaging 19.8% between 1961 and 1966, to 30.4% in 1967. After remaining around 30% until 1971, the defense share decreased abruptly to 17% in 1972, and continued to decline throughout the 1980s. Officially, in both 1989 and 1990 the defense share remained at 12%, and for 1991 it was 12.3% with 11.6% planned for 1992. The declining trend was consistent with the government's announced intentions to stimulate economic development and increase the social benefits. However, Western experts have estimated that actual military expenditures are higher than budget figures indicate.
