Poten)al & Improving Precision
• <<As the U.S., Canada, and other na)ons grow in diversity, different sampling frames may beier capture subgroups of the popula)on. […] We an)cipate that modular sampling designs using mul)ple frames will be widely used in the future.>> (Lohr & Rao, JASA 2006)

Dealing with Under-‐coverage Bias in Telephone Surveys
• Households with cell phone only not included in the tradi)onal frame for landline telephone survey
• Emerging evidence of significant differences between household with or/and without landline

In North America, Canada shows a slower trend with only 8% of CPO-HH as of December 2008 (Statis-
tics Canada, 2009). On the other hand, the United States is following the European trend (Blumberg &
Luke, 2009). In the first half of 2009, 22.7 percent of all households were cell phone-only households.
More importantly, differences between cell phone-only households and non cell phone-only households

Dealing with Under-‐coverage Bias in Telephone Surveys
• GESIS-‐Leibniz Ins)tut für Sozialwissenschaqen (2011): CELLA1, German Research Funda)on, DF telephone survey (Landline&Cell)
• (2014) Australian Gambling DF telephone survey: <<[…] reliance on a tradi)onal landline telephone sampling approach effec)vely excludes dis)nct subgroups of the popula)on […]>>

Dealing with Under-‐coverage Bias in Telephone Surveys
• (2002, Brick et al) Survey of America’s Facili)es, DF setup RDD households with landline telephone + area frame of households without landline telephone
• (2011) USA Behavioral Risk Factor Surveillance System <<[…] documented that samples from both frames are needed to avoid bias in key es)mates[…]>>

• Avoiding Screenings, before (MF è unique-‐frame) and aqer sampling (de-‐duplica)on)

MF Challenges & Issues
1. Increased inclusion probabili)es for unit overlap whether or not the unit is in fact selected in the final sample
2. Possibly overlapping frame-‐samples (duplicated unit) whether or not duplica)ons actually occur in the final sample
èEfficient MF es)ma)on requires addi)onal frame-‐level info to be collected beside the study variable in order to address such issues
