This document provides the high level summaries of research into changes in the 2017 Consumer Expenditure Diary Survey and Interview Survey. Findings are summarized in terms of the changes’ impact on data, perceived or measured burden, cost (where applicable), and finally whether the overall goal of the change was met.
Change and intent | Data | Burden | Cost | Goal Met? |
---|---|---|---|---|
Full diary double-placement to reduce cost, simplify data collection procedure | There was no limit to the drop-off in entries across weeks in initial 2 months vs. prior year, but there were more diary entries in both weeks. | NA | Impact on costs was inconclusive. | Simplified procedures |
Diary forms change to simplify details that previously made the diary task seem imposing for respondents | Minimal – although there was more reporting for section with more diary space, number of items reported were consistent. | NA | NA | Simplified form |
EPD/LPD (earliest/latest diary placement date) restrictions removed to increase response rates and simplify the collection process | Provisional analysis showed no across-the-board decline in the share of seasonal items that might have been affected by change. | There was a 65% decline in diaries ‘placed too late’ in the first half of 2017 versus 2016, and response rates appeared to increase. | Not analyzed | Increased response |
Interview construction section changes to reduce the burden on respondents | Analysis indicated changes in different directions in quarterly amounts reported for construction, but similar expenditure shares. | There was no overall change in section length (averaging 1.5 minutes) observed for those with positive durations in this section. | NA | Timing unchanged |
Mortgage question changes to improve data quality by better capturing current mortgage information from respondents | New question version indicated about 40% of respondents asked new question in initial quarter had a refinanced mortgage, and reported mortgage origination dates were more recent. | NA | NA | Undetermined (many respondents had inventoried data instead of getting new question), but initial findings promising |
Vehicle fuel question changes to only ask fuel expenditure follow-up questions for consumers with alternative vehicles | Similar (small) share of consumers reporting expenditures for these fuels. | There was an improvement by no longer asking fuel type questions for respondents without alternative fuel vehicles. | NA | Fuel questions asked of appropriate subset of respondents |
Earned Income Tax Credit question removal to improve data collected on this source of income | Producing amounts via tax estimation process limited underreporting found with collected estimate. | Eliminated a question previously asked of respondents. | NA | Improved estimate |
Transit questions revised to simplify the questions | Increased median amounts spent for transit were noted, signaling improved data quality. | Those reporting mass transit had section lengths that were, on average, 8 seconds longer in the 3 months following changes. | NA | Simplified question set |
Long-term care insurance now classified with other health insurance questions | There was a slight year-over-year decline in proportion reporting LTC in 2nd quarter 2017 and lower average premiums were reported. | Question now more logically classified amid other types of health insurance. | NA | Included with health section |
Health insurance changes intended to reduce measurement error | The incidence of misreported Medicare in private insurance decreased; however, there was a decrease in reporting of Medicare and Medicaid. | There was a slight increase in the proportion reporting ‘Don’t know’ or ‘Refused’ compared to the same months in 2016. | NA | Improvements in correct reporting of Medicare as public insurance |
Entertainment question changes to capture more detail in reporting of movie and park/museum expenses | There were increases in the proportion reporting these expenses and amounts reported, year-over-year in quarter 2. | Respondents encountered one additional response option for which to report expenses. | NA | More data reported on entertainment expenses |
Reference period changes to increase survey consistency among sections that ask total amount questions | Examination of equivalent months found decreased reporting for non-health insurance types, but the question itself was not significant when controlling for other factors. Amounts reported for mortgage pre-payments increased. | Results showed minor increases in the proportion reporting ‘Don’t Know’ and ‘Refusal’ responses for many types of insurance. For mortgage prepayments, there were lower missing data rates with the new questions. | NA | Greater consistency in how questions asked |
Interview burden measurement to examine changes in time and responses to burden questions | NA | Mixed findings; the length of the interview did increase in 2017, particularly due to an increase in the health care section, but perceived burden and the proportion saying survey was ‘too long’ decreased when compared with questions asked in 2013. | NA | Respondents reporting feeling less burdened despite increase in average interview time |
