Issues in the measurement of social determinants of health.

This article focuses on the measurement of the social determinants of health, and specifically on issues relating to two key variables relevant to the analysis of public health information: poverty and inequality. Although the paper has been written from the perspective of economics, the discipline of the two authors, it is also of relevance to researchers in other disciplines. It is argued that there is a need to ensure that, when considering measurement in this largely neglected area of research, sufficient thought is given to the relationships that are being examined or assessed. We argue further that any attempt at measurement in this area must take into account the historical backdrop and the complex nature of the relationships between these key variables.
