Samenvatting
An attempt is made to characterize the socio- economic state and the temporal evolution of countries by the use of labor force distribution data on a multi- dimensional phase plot so that the development of a country is represented by an evolutionary track of a phase point. The evolutionary tracks of several countries are examined, and the phase points of many countries are compared. Snowflake diagrams, which make easy comparison of the socio- economic character of various countries, have also been developed.
