Carl-Erik Särndal (born 1937) is a Swedish-Canadian statistician. specializing in survey statistics. He held professorial appointments at Umeå University; University of British Columbia, Université de Montréal, and Statistics Sweden, Stockholm. He specialized in survey theory and methodology, especially with applications to official statistics production for a country. He worked, periodically, as researcher, expert and/or consultant, at national statistical agencies: Statistics Canada (Ottawa), Statistics Sweden (Stockholm) and Statistics Finland (Helsinki).

Education and professional years Carl-Erik Särndal grew up in Sweden. He attended Lund University, where he earned a Bachelor of Science degree in 1957, and a PhD in statistics in 1962. He was a professor at the Department of Statistics, Umeå University, Sweden, 1967–1970; Division of Management Science, Faculty of Commerce & Business Administration, University of British Columbia, Vancouver, 1970–1980; Département de mathématiques et de statistique, Université de Montréal, 1980–1997; Statistics Sweden, 1997–2002.

Research Model assisted design-based inference; uses of auxiliary information in estimation; generalized regression (GREG) estimation; calibration weighting, in particular for survey nonresponse; critical examination of the probability sampling paradigm.
