1. A computer implemented process for delinking entity representations in a computer implemented electronic database using a bloat index formula, the electronic database comprising a plurality of entity representations, each entity representation comprising a plurality of linked electronic records, each electronic record comprising a plurality of fields, each field capable of containing a field value, the process comprising: calculating a field inconsistency weight for a plurality of fields, wherein each field inconsistency weight is derived from a field inconsistency probability associated with the corresponding field and each field inconsistency probability reflects a likelihood that an arbitrary entity representation includes records with different field values in the corresponding field; selecting an entity representation in the electronic database; calculating a bloat index reflecting a sum of field inconsistency weights over a plurality of fields common to a plurality of linked electronic records of the selected entity representation; determining, based on the bloat index and a size of a population associated with the database, whether there is a sufficiently high confidence level that the plurality of linked electronic records of the entity representation do not correspond to a same individual; and delinking, in the electronic database, the plurality of linked electronic records of the entity representation based on the determining.
