This report lists and compares key analytical and methodological differences between the 2002 Vehicle Inventory and Use Survey (VIUS) and 2021 VIUS. Three key findings are discussed. First, differences in data fields and survey methodologies indicate trending between the two surveys should be limited to contextual and historical applications. Second, the 2021 VIUS included 31 new data fields. Finally, several methodological changes (e.g., survey instrument differences paper versus online, weighting plan updates, geographic coverage, and response rate reductions impacting confidence intervals) may impact comparisons between the 2002 VIUS and 2021 VIUS.
