As individuals hold more and more data about themselves and their activities on their own databases (see Personal Knowledge Banks) the more able they are to mine and analyze this data to generate the insights they need to make better decisions.

Personal data analytics adds value for users by:

• helping them track trends such as personal spending, calorie intake, household energy usage, car mileage, etc. This could take the form of an 'annual audit' or of ongoing, bespoke or one off analytical projects
• using 'people like you' comparisons to highlight areas where their resources could be better managed

Individuals (or households) may recognize needs for consultants or services to help manage the personal data, or to interpret and maximize the data for their betterment.
