Raising Response Rates in Mail Surveys of Small Business Owners: Results of an Experiment

Mail surveys of small business owners have notoriously low response rates, creating the potential for substantial error in surveys of this population and diminishing the credibility of research conducted on small firms. The author recently carried out an experiment as part of a larger project involving 16,000 small business owner/members of the National Federation of Independent Business (NFIB). The experiment's purpose was to ascertain survey treatments that might enhance mail survey response among small business owners. Results showed that none of the six treatments examined improved response rates enough to warrant its routine use over the alternative, nor did any combinations of treatments help. The implication is that commonly used treatments, for example prenotification, often are unproductive.
