OK - I found some GINI data on Yugoslavia, (A World Bank Spreadsheet). Apparently the problem is that Eastern Bloc nation data from this period is very unreliable.
Here are the Yugoslavia numbers: Year Low High 1963 24.63 34.51 1964 23.00 23.00 1965 30.60 30.60 1966 23.00 27.20 1967 24.00 25.80 1968 17.91 34.74 1969 24.00 26.00 1970 25.00 25.00 1971 23.00 24.30 1972 22.80 23.00 1973 22.00 32.00 1974 21.00 22.70 1975 21.00 21.80 1976 21.00 21.40 Note that I included a high and low for each year. Generally there is more than one of them per year. If you graph them there is a very spiky result, but I admit it tends slightly downward. Tomorrow maybe someone else can find similar data for the then Soviet Union or for Poland or Rumania. Most of these data points are from source rated by the WB to be inconsistent, or from samples not representing the whole country or from incomplete and unreliable tax records and so forth... In short I don't know if this Gini is meaningful...
