This chapter studies the quality of health and health inequality among racial/ethnic groups as well as across geographic areas of the State of New York, and focuses on income-related health inequality. The chapter generates a continuous measure of health by modeling the five-category self-assessed health (SAH) as an Ordered Probit Model conditioned by several objective determinants including different diseases, behavioral risk factors, and socio-demographic characteristics. It is organized as follows: The estimation procedures-the methods to calculate quality of health; describes income related health inequality and their determinant; documents the data used in the empirical analysis is documented; presents the results; and finally summarizes the conclusions. The chapter uses an ordered response model to transform the order scale variable into a cardinal variable. It offers New York health policy makers certain guidelines to eliminate health disparity in the population.
