Sample rotation and estimation in the Survey of Employment, Payroll and Hours

The current Survey of Employment, Payroll and Hours, conducted by the Labour Division of Statistics Canada is a major monthly survey collecting data from a large sample of business establishments. This paper describes the methodology of the survey. The description of the stratification, sample size determination and allocation procedures is brief, whereas the description of the rotation procedure is more detailed because of its complexity. Some of the possible simplifications of the design are also highlighted.
