ABSTRACT
The first important conclusion concerns the frequency of occurrence of important social disturbances in the life of social bodies. Usually it is thought that they are fairly infrequent events. Meanwhile the data at hand show — and show consistently for all the countries studied — that on the average one notable social disturbance happens in about six years, for some countries in five years, for others in seventeen years. If, instead of taking the average time span per significant social disturbance, we ask ourselves what is the average number of years without a disturbance per years with a disturbance, then the results will be still more striking. They indicate that the relationship between the years with disturbances and those without them fluctuates between one to two and one to eight, depending upon the country. On the average in most of the countries studied, to one year with a significant social disturbance there have been only about five peaceful years, free from inner social tensions and storms. Table 48 gives more exact data in the field.
