Abstract:

In-person surveys that use address-based sampling are often based on area segments defined by census geography rather than postal geography. Census geography enables more accurate inclusion of demographic information in the sample selection procedures and the use of frame supplementation methods to increase coverage. However, area frames based on census geography contain more frame error than frames based on postal geography because addresses must be allocated (i.e. geocoded) into area segments. When addresses are incorrectly geocoded into area segments, sampling inefficiencies occur. We examine data from the 2009 National Survey on Drug Use and Health to determine the extent of geocoding error in sampled segments and its implications on coverage and efficiency of area frame samples.
