Health Disparities Calculator (HD*Calc)
Latest Release: Version 1.2.3 - October 24, 2012

The Health Disparities Calculator (HD*Calc) is statistical software designed to generate multiple summary measures to evaluate and monitor health disparities (HD). HD*Calc was created as an extension of SEER*Stat that allows the user to import SEER data or other population-based health data and calculate any of eleven disparity measurements.

HD*Calc supports the use of a range of health disparities measures, allowing researchers to select and apply different measures to their data. HD*Calc was originally developed to expand the range of measures for evaluating health disparities related to cancer. However, since it can be used with any dataset, HD*Calc can be used in any research arena. Cross-sectional and trend data (e.g., cancer rates, survival, stage at diagnosis) categorized by disparity groups (e.g., area-socioeconomic status, race/ethnicity, geographic areas) can be imported into HD*Calc to generate four absolute and seven relative summary measures of disparity. The results are displayed as tables and charts, which may be exported for use in other applications. Read more about Health Disparity Measures in HD*Calc.
