Abstract: A method and system for creating objective health scores for an individual, based on normalized, aggregate data. The system creates the scores abased on user input, as well as on data collected from third party sources. The third party sources include wearable fitness trackers, sources that provide information on sleep patterns, and further include information relating to financial transactions. The financial transaction information provides the system with information about the user's food purchases. The system categorizes the data into categories and subcategories, normalizes it against a normalized distribution model, and calculates health scores for the user's fitness, nutrition and sleep, as well as an aggregate, or universal, health score.
