In 1993 the Census Bureau implemented the Spanish Forms Availability Test (SFAT). The SFAT was part of a research and development program by the Census Bureau designed to assist in formulating policy and design options for the Year 2000 Census of Population and Housing. The purpose of the test was to determine the effect of the availability of mailing Spanish forms to targeted areas with high concentrations of persons who speak Spanish and who do not speak English well or at all. Specifically, the test sought to determine whether making Spanish forms available would increase response rates in target areas, assess the reaction of non-Hispanics living in those areas to receiving Spanish forms and determine the effect on item nonresponse.
