Systems and methods for providing relatively timely demographic data, and in some embodiments, demographic data that can be particularly helpful for local, neighborhood, program or project level decisions. Two or more source databases which are updated periodically are accessed and provide demographic or other data relating to street addresses, households, parcels of land, or other predetermined identifiers within a predefined geographic region. The demographic data from each of the source databases is preferably associated with a corresponding street address, household, parcel of land, or other identifier within the predefined geographic region. To protect the identify of the individual residents within the predefined geographic region, the demographic data for each street address, household, parcel of land or other identifier is preferably rolled together with at least one other street addresses, household, parcel of land or identifier. This creates a number of aggregate data sets, one for each group or set of street addresses, households, parcels of land or other identifiers. A user can then access or generate queries from the aggregate data sets or a summary thereof.
