Objective. To describe factors that will shape future demand for doctoral-trained health services researchers. Study Design/Data Sources. Commentary based on recent trends in funding for health services research (HSR), the number of federally funded HSR projects listed in HSRProj, national expenditures for health, and interviews with a small number of employers. Principal Findings. Despite rapid growth in the overall health care sector, inflationadjusted funding for HSR has declined, implying little or no net growth in demand for people to lead HSR studies. Employers report being able to hire researchers to conduct HSR by drawing on people trained in many disciplines. Conclusion. Employers have considerable flexibility in hiring individuals to conduct HSR when demand is relatively stable. They may have much more difficulty hiring well-qualified researchers when faced with sharp increases in demand for HSR, such as could be generated by recent economic stimulus legislation.Key Words. Health services researchers, HSR job market As national health expenditures (NHE) increase and policy makers investigate ways to control costs, promote quality, and improve health, there is potential for growth in the demand for health services research (HSR) and health services researchers. However, the demand for HSR and the corresponding resources allocated to HSR compete with other federal and state government priorities as well as with health-related funding for clinical and basic science research. Thus, the future demand for health services researchers remains uncertain, along with the relative demand for researchers trained in the field of HSR and those trained in any of the numerous other fields that study health services delivery, financing, and performance.This uncertainty means that demand for health services researchers from universities, research organizations, government, or private industry in the year 2020 cannot be forecast with precision. Nevertheless, it is useful to describe the factors that may influence the underlying demand for HSR and r Health Research and Educational Trust
