米国における日本生まれの日本人の諸特性―学生，学生以外，および日本以外で生まれたアメリカ市民の近年の妻―

抄録

Our primary goal in writing this paper is to demonstrate the usefulness of micro data for research in social science so that a strong movement can emerge in Japan to persuade governmental and other agencies to make representative micro data sets widely available to researchers. Based on the merged micro data of the 2005, 2006, and 2007 American Community Surveys, we have found several features of the Japan-born Japanese residents in the United States that can be interpreted as reflections of the strong influences of the male breadwinner model and the Japanese-style employment system on the Japanese in Japan. These features include (1) the high proportion of post-secondary students being undergraduate rather than graduate students, (2) strong female-domination in the sex-compositions of both students and non-students, and (3) among non-students, very large gender gaps in educational attainment, employment rate, and wage level. For the subpopulation of the Japan-born Japanese brides of non-Japan-born American citizens, these influences were also reflected in their strong tendency to be in hypergamy and their relatively low employment rate. Reflecting the history of interactions between Japan and the United States, the Japan-born Japanese residents in the United States are found to show disproportionately heavy concentrations in the states of California and Hawaii and especially in the Los Angeles metropolitan area.
