2 Challenges – Cell Phones Close to 20% household are cell-phone-only (CPO) Mapping no longer 1-1 One individual can own several numbers Several individuals can share the same number More difficult to link number to geographical location Data collection Safety Compensation Separate frame
3
3 Challenges – Response Rates OMB used to insist on 80% Now 60% is difficult to achieve Decrease in response rates results in increase in survey costs Decrease in response rates leads in increased risk of nonresponse bias
4
4 Challenges – New Technologies Traditional approaches Landline phone endangered species In-person too expensive Internet/Web Smart phones Other
5
5 Future Directions – Multiple Frames Cell phone and landline phone Address lists (see below) and phone lists Internet data bases Commercial lists Administrative data/large data bases External sources of information Disclosure control/confidentiality Data linkage
6
6 Future Directions – Address-Based Sample Complete list of addresses Process Select sample of addresses Match as many addresses with telephone numbers as possible Use multiple modes (mail, telephone, in-person, internet) to collect data Nielsen Moved from telephone to ABS last November “RDD is dead”
7
7 Future Directions – Internet Surveys Coverage and selection bias Harris – large base Frame bias Membership bias “Professional respondents” Is it possible to model to overcome shortcomings? Knowledge Networks
8
8 Future Directions – Multi-Mode Offer respondents a choice Increase cooperation Select optimal mode as a function of: survey topic target population(s) However, beware of mode effects Adjust mode during field period
9
9 Future Directions – GIS Frame building Sample selection Screening Data collection
10
10 Future Directions - GIS
11
11 Future Directions – Rolling Samples Increase sample size by combining samples over time E.g., American Community Survey (ACS) Sampling and sampling errors more complex
12
12 Future Directions – Nonresponse Bias Gauge survey quality using nonresponse bias rather than response rates Correlation need not be high Challenges How to measure bias? How to standardize measurement process?
13
13 Future Directions – Responsive Design Adaptive/responsive surveys Requires multi-mode, flexible approach Requires monitoring during data collection Adjust strategies “mid-stream” Cumulating knowledge Sampling Interviewing
14
14 Conclusions Surveys of the future will be more complex Need to be flexible Need to be creative Future looks very interesting, albeit not very clear
