There are ongoing concerns about the reliability of household expenditure surveys in many countries. This chapter presents a comparative assessment of the performance of the household expenditure survey programs in Australia, Canada, the UK and US. We first assess the coverage of aggregate expenditure relative to national account benchmarks. It is found that the fall in response rates over time is predictive of changes in coverage rates within countries. Further, the growing concentration of income has been associated with an increasing concentration of expenditures which has not been captured well by the micro surveys. Turning to coverage rates for specific expenditure components, we find high and stable coverage of regularly purchased items, along with more volatile coverage of irregular and larger expenditure items. Therefore the aggregate patterns in coverage cannot be readily attributed to specific expenditure components or collection methods.
