Current Topics in Survey Sampling contains all the invited papers as well as abstracts of the contributed papers presented at the International Symposium on Survey Sampling held at Carleton University in Ottawa, 7-9 May 1980. The topics covered here include nonsampling errors, current survey research activity, superpopulation models, variance estimation, and imputation techniques. The symposium was also dedicated to the memory of Professor William G. Cochran. The volume is organized into six parts. Part I includes papers by Cochran's close colleagues. Part II contains three papers on nonsampling errors. These cover the creation of a unified discipline of survey research to serve as the basis for total survey design; a''swapping algorithm''for interviewer assignment to minimize the effect of nonsampling errors; and the question of whether census counts should be adjusted for underenumeration when determining federal transfer payments to the provinces. Part III describes research activities at four major survey organizations in North America: Research Triangle Institute, Statistics Canada, Survey Research Center of the University of Michigan, and U. S. Bureau of the Census. Part IV discusses the use of superpopulation models in survey design and inference. Part V tackles a number of different problems in variance estimation while Part VI deals with imputation techniques.
