Are Voter Rolls Suitable Sampling Frames for Household Surveys? Evidence from India

Abstract

We examine the use of publicly available voter rolls for household survey sampling as an alternative to household listings or field-based sampling methods. Using voter rolls for sampling can save most of the cost of constructing a sampling frame relative to a household listing, but there is limited evidence about their accuracy and completeness. We conducted a household listing in 13 polling stations in India comprising 2,416 households across four states and compared the listing to voter rolls for the same polling stations. We show that voter rolls include 91% of the households found in the household listing. We conduct simulations to show that sampling from voter rolls produces estimates of household-level economic variables with minimal bias. These results suggest that voter rolls may be suitable for constructing household sampling frames, particularly in rural India.
