Abstract:
|
The American Community Survey (ACS) produced its first nationwide 5-year estimates in 2010, using sample data from 2005 through 2009. With five years' worth of sample, the combined sample size in some areas would be large enough that a finite population correction (FPC) factor might have a noticeable impact on variances. This paper will discuss the methodology used to incorporate an FPC factor into the 5-year ACS variance estimates, and how the method was adapted to account for the subsampling of nonrespondents . Results comparing the impact on the variance of using the FPC across a broad spectrum of estimates and geographic areas will also be presented. Preliminary work indicated improvements in the standard error estimates of between two and four percent could be achieved.
