Case studies on the use and accuracy of synthetic estimates: unemployment and housing applications.

A description is given of unemployment synthetic estimates for counties, based on the 1970 Census of Population. The distribution of the method error of these estimates is given, as well as the relative accuracy of these estimates. Implications for intercensal estimates based on regression models are considered. Vacancy rates from the 1970 Census of Housing are discussed. Estimates of 1970 estimates of dilapidated housing units with all plumbing facilities and their accuracy are analyzed.
