Abstract:

Missing data are a potentially important problem when trying to measure household wealth and income through survey questions. A relatively simple survey method, i.e., unfolding follow-up questions asking respondents to place themselves in or out of a particular dollar range, appreciably improves the quality of household economic data and significantly reduces item non-response (Juster and Smith 1997). However, the choice of values for the follow-up questions can affect population parameter estimates (Hurd 1999). This paper analyzes the effect of the initial entry point into follow-up questions on financial variables on the resulting imputed distribution of those variables. We use data from the second wave of the household survey component of Healthcare for Communities, which employed unfolding follow-up questions with randomized entry points.
