This is a study of discrimination as it was experienced by blacks and Japanese- Canadians living in Hamilton, Ontario. The report was based on 204 interviews conducted during the summer of 1964. In the interviews the respondents discussed their experiences in housing, work, and public accommodations. Respondents were encouraged to elaborate on any difficulties mentioned and the reasons for these difficulties. If any of the respondents reported that a difficulty was encountered because of race, this was considered to be an incident of discrimination. Factors associated with perceived discrimination among Japanese-Canadians included the following: a relatively high income, frequent social interaction with non-Japanese, and related factors such as preference for speaking English, and differences of religion within the family. Factors associated with the experience of discrimination among blacks are the following: a relatively low income, frequent social interaction with non-Negroes, youth, marriage to a white person, dark skin, and growing up in Hamilton. None of the factors considered in the study explained why blacks experienced more discrimination than Japanese-Canadians. (Author/AM)
