Abstract: A method for appending each record of a first database with a record from a second database. The records of the first database relate to information pertaining to a specific geographical location, such as an individual residing at a defined residence, or an average or other metric pertaining to all members residing at a defined residence. The second database comprises records containing statistical information pertaining to an overall population within a defined geographical area. The method further provides, for each record of the first database, identifying a record from the second database having a defined geographical area containing the specific geographical location of the record of the first database, and appending the information or fields of the second database record to the first database record.
