There have been some significant changes in this edition. The Literacy entry now includes rates for males, females, and both sexes. Appendix C: International Organizations and Groups is new and includes date established, aim, and list of members. Three maps of special interest have been added this year—republics of the Soviet Union, ethnic groups in the Soviet Union, and ethnic groups in Eastern Europe.
