Version V2

This data collection is a sociohistorical study of the ways in which three generations (Issei, Nisei, and Sansei) of Japanese American families adapted to social, cultural, educational, occupational, and other institutions of American life. The study examines the experience of the first immigrants to the United States (Issei), and their children (Nisei) and grandchildren (Sansei). Interviews with Issei families stressed the difficulties faced by the immigrants during their early years in the United States, as well as aspects of social and cultural life. Interviews with Nisei included questions on employment, attitudes toward work, income, education, marriage, social relationships, discrimination, and religion. Topics covered in Sansei interviews included birth order, age, marital status, children, social relationships, occupation, industry, income, education, Japanese value systems, marital choices, influence of parents and grandparents, discrimination, religion, political attitudes, and migration.

For reasons of confidentiality, the third column (city, county) of all location codes in all three files was blanked with zeros. The first two columns (section, state) of the affected 19 variables remain intact.

Each generation in this study is a representative nationwide mainland United States sample. The Issei sample was chosen from a project listing 18,000 Issei who survived until 1962 and lived on the United States mainland. It is stratified by county and is designed to achieve equal representation of those living in neighborhoods of six different levels of housing quality. The sample is further stratified to represent the density of the population of the Japanese-American community within each county. Nisei and Sansei respondents were obtained by requesting the names and addresses of children and grandchildren from the parents.

The Issei sample was chosen from a project listing 18,000 Issei who survived until 1962 and lived on the United States mainland.

ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Standardized missing values.
