A Comparison of Specific Efforts that Japan and Russia Should Endeavor to Undertake: In Light of Different Population Proportions by Age Group in Countries with the World's Largest Populations

摘要

Introduction: The world and Japan both face various social issues. Those issues must be researched and dealt with. Researching those issues and devising ways to deal with them involves a multi-faceted approach. Measures need to be recommended for individual countries based on the results of those efforts. Materials and Methods: 1) Ten countries with the world's largest populations in 2015 were examined. 2) The proportions of 3 age groups in the population were examined in those countries (2 countries were excluded since data were not available). Two of the countries were Japan and Russia. Based on 1) and 2), additional aspects that Japan and Russia need to consider were compared and recommendations were made. Results: 1) Population figures for China, India, the United States of America, Indonesia, Brazil, Pakistan, Nigeria, Bangladesh, Russia, and Japan were indicated. 2) Additional efforts need to be devised for the working-age population in Russia and the working-age population and the elderly population in Japan. Conclusion: Measures targeting certain age groups need to be promptly considered in individual countries. In addition, issues must be examined on a regional basis and measures to deal with those issues must be devised in individual countries. Experts in relevant fields, relevant bodies, and the public also need to act in concert to undertake those efforts.
