In this paper we present the empirical results of a sampling survey of construction firms of the town of Ravenna. The univariate stratification procedure was used as sampling technique and the number of hired workers was taken as stratification variable. The procedure developed by Dalenius and Hodges (1959) for the division of firms’ population into strata and the optimal allocation for the choices of the relative sample sizes were applied to all firms with the stratification variable different from zero every months: from January 1979 to September 1980. The series of the boundaries of the strata and those of the relative sampling sizes for the same period were obtained and the means of the series were taken to construct the sampling. The results of the inquiry, the weights, and the relative efficiency with the respect to the traditional sampling are reported.

Abstract

In this paper we present the empirical results of a sampling survey of construction firms of the town of Ravenna. The univariate stratification procedure was used as sampling technique and the number of hired workers was taken as stratification variable. The procedure developed by Dalenius and Hodges (1959) for the division of firms’ population into strata and the optimal allocation for the choices of the relative sample sizes were applied to all firms with the stratification variable different from zero every months: from January 1979 to September 1980. The series of the boundaries of the strata and those of the relative sampling sizes for the same period were obtained and the means of the series were taken to construct the sampling. The results of the inquiry, the weights, and the relative efficiency with the respect to the traditional sampling are reported.
