The Institute for Social Research (ISR) at the University of Michigan successfully led an intensive, long-term, in-person survey for the Moving to Opportunity (MTO) for Fair Housing demonstration final impacts evaluation (Sanbonmatsu et al., 2011), achieving final effective response rates (ERRs) of 89.6 percent among MTO adults and 88.7 percent among youth, well above what response rates of surveys with comparable low-income populations have accomplished. A variety of survey field strategies ISR employed— careful staff selection, strategic use of financial incentives, and close collaboration between ISR and the National Bureau of Economic Research—all contributed to these high ERRs. The high costs associated with achieving high ERRs for in-person surveys like that employed in MTO raises questions about added value. Costs per survey interview nearly quadrupled during the last 4 fielding months. This extra investment increased the MTO adult survey ERR by only about 3.2 percentage points. A reanalysis of intention-to-treat estimates on selected outcomes suggests the merits of such an investment. If survey fielding had stopped at an 81-percent ERR for adults, we would have falsely concluded that MTO had no effect on two of four key health outcomes, that MTO had no effect on female youth mental health, and that MTO increased female youth idleness.
