Telephone interviews were conducted to compare reported and true date of birth and salary for 105 Mexican American, 219 Anglo American, and 134 black city employees in San Antonio, Texas. The Anglo and Mexican American samples were randomly selected from the police and fire departments; the blacks, not being concentrated in sufficient numbers in any few departments, were taken from all 22 city departments. Telephone numbers and data about sex, birth, and employment dates, and salary were obtained from a document filled out by employees in the Personnel Department. A questionnaire was written to guide in eliciting responses about the same factual information taken from the personnel records. Two Anglo females who were experienced in interviewing for scholarly and commercial research conducted the interviews. Significance of differences tests were conducted with the chi-square procedure. Inaccurate responses were categorized into over- and understatement. Some findings were: (1) of the 455 responses to the birth date question, 20 of the Anglo, 9 of the Mexican American, and 21 of the black responses were inaccurate; (2) of the 389 responses to the salary question, only 33 were correct within one dollar; and (3) the younger, but less well-paid blacks tended to report their salaries more accurately.
