Objective. Immigration scholars have found that the highly educated and political liberals are considerably less likely to support restrictionist immigration policies than other groups. I ask whether the influence of social desirability pressures in the survey interview is responsible for this finding. Methods. An unobtrusive questioning technique known as the list experiment is used to measure Americans' support for immigration restrictionism. The list experiment can easily be embedded in a standard telephone survey and has been used by previous investigators to study racial attitudes. Results. Restrictionist sentiments are found to be more widespread among the U.S. populace than previous studies have estimated, especially among college graduates and political liberals. Conclusion. My findings have implications for immigration scholars and social scientists who study other sensitive attitudes and behaviors. The most commonly employed strategies to reduce socially desirable responding may not be enough.

BackgroundWe examine who pays for services that support disabled older Americans at home. We consider both personal sources (e.g., out-of-pocket payment, family members) and publicly funded programs (e.g., Medicaid) as sources of payment for services. We examine how the funding mix for home care services is related to older people’s economic resources, needs for care, and other socio-demographic characteristics.MethodsOur sample consists of 11,725 person-years from the 1989, 1994, 1999, and 2004 waves of the National Long-Term Care Survey. Two-part regression analyses were performed to model hours of care received from each payer. “Random effects” and “fixed effects” estimation yielded similar results.ResultsAbout six in ten caregivers (63 %) providing home care services are paid by personal sources alone. By contrast, 28 % receive payment from publicly funded programs alone, and 9 % from a combination of personal and public program sources. Older people with family incomes over 75,000 dollars per year receive 8.5 more hours of home care overall than those in the lowest income category (less than 15,000 dollars). While the funding mix for home care services is strongly related to older people’s economic resources, in all income groups at least 65 % of services are provided by caregivers paid in whole or in part from personal sources. In fact, almost all (97 %) home care received by those with family incomes over 75,000 dollars per year are financed by personal sources alone.ConclusionsWe outline the implications that heavy reliance on personally financed services and economic disparities in overall services use has for disabled older Americans and their families.Electronic supplementary materialThe online version of this article (doi:10.1186/s12913-015-0978-x) contains supplementary material, which is available to authorized users.

Because individual caregivers' time burden has remained fairly constant since at least 1989, advocacy on behalf of policies that promote more and better support for caregivers is appropriate.
