Healthy People 2010 goals included the reduction of cancer disparities related to cancer mortality and morbidity, cancer screening, preventive interventions, and risk factors. In addition to the goals of Healthy People 2010, it is of highest priority to the National Cancer Institute (NCI) to eliminate health disparities among various subpopulations of the nation. It has become clear that the method of analysis used to examine cancer related health disparities impacts the results. Specifically the statistical properties of individual measures used to determine the direction and magnitude of cancer related health disparities affects the results and evaluation of trends.

NCI hired JSI to complete the Health Disparities Calculator (HD*Calc) Dissemination Project. The purpose of this project was to manage the completion and dissemination of a software application, that can be used as an extension of SEER*Stat to calculate multiple measures of cancer-related health disparities from Surveillance Epidemiology and End Results (SEER) data. The application can also be applied to other population-based public health data sources. The Health Disparities Calculator Dissemination Project aimed to facilitate the use of a range of health disparities summary measures so that researchers can explore their utility in different situations; encourage examination of health disparities statistics in population-based health data; and promote the evaluation and monitoring of health disparities using data from SEER.
