Empirical Results of Two Sample Design Options for Sampling for the Count by C.T. Isaki, J.H. Tsay, and Y. Thibaudeau I. Introduction Sampling for the count or sample census is a scenario in which a sample of units is selected from a frame and a data collection procedure is used to obtain responses from those units in the sample. For units not in sample, estimates of their characteristics are provided based on sample information. Given the time constraints imposed, two sample designs were developed for study. The two sample designs consisted of one that utilized the block as a sample unit, and another that used the mail address as a sample unit. A. Background The sampling for the count scenario assumes that a 1990 type list universe is to be used. Such a list provides mail information by block for Tape Address Register (TAR), Pre-list, and Pre-list pocket areas. Other areas such as Update Leave (U/L) and List Enumerate (L/E) were not "mail out" areas and were deemed out of scope for sampling purposes. The list also identifies group quarters. Since group quarters were not canvassed by mail and varied in size, they were not to be sampled for our study purposes, but were assumed to be covered 100% via other means. The characteristics studied were those relevant to provide Voting Rights data.
