Problems of Screening for Poverty Status
John F. Moeller and Nancy A. Mathiowetz
Abstract:The 1987 National Medical Expenditure Survey used a screening interview conducted in the fall of 1986 to identify individuals of interest for over sampling, including the poor and near poor. To minimize response burden and nonresponse, a single question was asked to determine poverty status. In addition to the potential for measurement error, the dynamic nature of poverty confounds the problem of identifying “survey-year” poor in a screening interview. This paper examines a more efficient approach for screening for poverty status, given both the propensity for underreporting income and the dynamic nature of the measure.
Keywords:Measurement error; oversampling; misclassification; statistical modeling; expected income.
