Presented are national statistics on the 1960-62 employment conditions of America's scientific and engineering manpower in relation to economic and social characteristics. The eight-page questionnaire used in the 1962 postcensal survey is concerned with the collection of data from individuals classified as scientists and engineers in the 1960 Decennial Census of Population. A total of 37 tables is provided in this report to illustrate the following topics: stability of employment, occupation, work activities, and type of employer for employed engineers and scientists; career patterns, including work histories of employer and occupational turnover, and occupational origins; educational preparation, including formal and nonformal training and change in this preparation over time; and the personal, social, and professional characteristics of scientists and engineers, covering citizenship, marital status, residence, salaries, and income. Included in the appendices are an example questionnaire, a fields of specialization list, two descriptions of the postcensal studies program, two tables of universe estimates, and ten tables of standard errors of absolutes and percentages.
