Abstract: A method for aggregate reporting of health data includes obtaining health data for a plurality of subjects in a population associated with an entity, the health data comprising diagnostic laboratory testing results, biometric information, or demographic information. Each of the subjects is allocated to one or more dimensions based on the obtained health data and one or more boundary conditions of each of the dimensions, the dimensions corresponding to biometric or demographic information of a specified type. Whether a number of subjects allocated to one of the dimensions is below a threshold is determined. One or more of the boundary conditions for one or more of the dimensions is adjusted when the number of subjects allocated to the one dimension is determined to be below the threshold. The determining and the adjusting are repeated until a number of subjects allocated to the dimensions is not below the threshold.
