Abstract
Clyde Tucker, Robert Casady, and James Lepkowski (1992) "The Allocation of Sample Size In Stratified Telephone
Sample Designs," Proceedings of the Section on Survey
Research Methods, American Statistical Association, forthcoming.
Stratified telephone sample designs have been proposed
which provide samples of phone numbers that have high
concentrations of working residential telephone numbers but
require little replacement sampling. These designs use
commercial lists of telephone numbers to create sampling
strata based on counts of listed residential numbers.
Disproportionate allocation of sample size to strata composed
of banks with listed numbers and to strata of banks without
listed numbers has been considered as a means of increasing
design efficiency. This paper uses recent empirical results
to improve the specification of optimal stratified sample
designs in different survey contexts. In particular, an
informed discussion of sampling from banks without listed
numbers (so-called "low-density" strata) is given.
