Recently, the transnational migration of nurses from developing countries to developed countries has received heightened attention from policymakers, health-care practitioners, and the media. In this article, the 1990 and 2000 Census Public Use Micro Survey (PUMS) data files are used to address the issue of nurse migration. I examine changes in the number, location, wages, countries of origin, and other economic and demographic variables for foreign-born nurses and nurses' aides and US born nurses and nurses' aides over the time period 1990 to 2000. I find that foreign-born nurses and nurses' aides increasingly come from developing countries and, specifically, from Africa. This raises important ethical issues, as Africa faces a severe shortage of nurses in the context of the AIDS crisis. Foreign-born nurses are shown to have higher levels of education and higher levels of labor force attachment than US-born nurses.Since 2002, the transnational migration of nurses from developing countries to developed countries has received heightened attention from policymakers, health-care practitioners, and the media. Globalization, including technological improvements in communications such as the internet, has lowered the costs for matching up employers in hospitals and nursing homes in developed countries with health-care professionals in developing countries such as India, the Philippines, and Nigeria. Hospitals and nursing homes hire agencies to recruit nurses and doctors from developing countries in order to fill vacancies that are difficult to fill with domestic health workers (Brush et al., 2004;Rai, 2003). Greater economic integration among countries and the low cost of transportation have made it easier to cross borders.The economic and demographic forces that drive developed country hospitals and nursing homes to search for nurses in developing countries are expected to strengthen in the next
