Technical notes concerning the Survey of Income and Education (SIE), April-July 1976, which was conducted by the Bureau of the Census for the Department of Health, Education, and Welfare, are presented. Information is presented on the source of the data, sample design, estimation procedure, reliability of the estimates, nonsampling variability, sampling error, and standard errors. Estimates for the SIE were based on data collected from personal interviews from U.S. households. Each state was divided into areas made up of counties and independent cities referred to as primary sampling units. The SIE sample was a stratified multistage cluster design. A ratio estimation procedure was used to correct for coverage deficiencies. Variance parameters for national estimates of college enrollment/attainment and income are provided for the analysis groups used in the series of reports on the characteristics of postsecondary students. The use of parameters along with a comparison of percentages are illustrated. The standard error for a difference between two sample estimates is also covered. Definitions of terms used in the survey and a sample questionnaire are included. (SW)
