Abstract

A method and system are disclosed for segmenting a population, and include the defining of a base level population segmentation tree. A set of alternative level variables usable as substitutes in the nodes of the population segmentation tree are defined. Substitute split values for each node of the tree are determined to enable up and down shifting between levels.

Claims

1. A method of market segmentation, comprising:

creating a master address list containing a plurality of residential addresses;

removing duplicate addresses in the master address list;

coding addresses in the master address list with additional geographic identifiers;

summarizing the addresses into at least one of the geographic identifiers;

comparing the summarized addresses to an estimate from another source; and

inserting token records in the master address list when under-counts are discovered in the comparison.

2. The method according to claim 1, further comprising creating preliminary housing unit and household counts for each address.

3. The method according to claim 2, wherein creating preliminary housing unit and household counts includes distinguishing between single-unit and multiple-unit addresses and categorizing tenure.

4. The method according to claim 2, whereby creating preliminary housing unit and household counts is accomplished in a manner consistent with Bureau of Census definitions.

5. The method according to claim 3, further comprising re-examining the geographic identifier assigned to the addresses and the distinguishing between single-unit and multiple-unit addresses when over-counts are discovered in the comparison.

6. The method according to claim 1, further comprising categorizing each address by the lowest geographical level of information available.

7. The method according to claim 1, further comprising appending high level segment code assignments to the master address list.

8. The method according to claim 7, further comprising creating a summarized list of the master address list summarized to the ZIP+6 level.

9. The method according to claim 8, further comprising assigning a first address with a first ZIP+6 code with a segment code associated with a household when only one set of household data exists for the first ZIP+6 code.

10. The method according to claim 8, further comprising assigning a second address with a second ZIP+6 code with an averaged segment code when multiple household records share the second ZIP+6 code.

11. The method according to claim 9, further comprising appending the segment code to the master address list.

12. The method according to claim 1, wherein the additional geographic identifiers include at least one of the group of ZIP+6, ZIP+4, ZIP code, Census Block Group, and tract.

13. A method of market segmentation, comprising:

creating a master address list coded with ZIP+6 geographic identifiers;

assigning a segment code to an address in the master address with a unique ZIP+6 code; and

appending the segment code to the master address list.

14. The method according to claim 13, wherein creating the master address list includes:

removing duplicate addresses in the master address list;

coding addresses in the master address list with additional geographic identifiers;

summarizing the addresses into at least on of the graphical identifiers; and

comparing the summarized addresses to an estimate from another source.

15. The method according to claim 14, further comprising inserting token records in the master address list when under-counts are discovered in the comparison.

16. The method according to claim 14, further comprising creating preliminary housing unit and household counts for each address.

17. The method according to claim 16, wherein creating preliminary housing unit and household counts includes distinguishing between single-unit and multiple-unit addresses.

18. The method according to claim 17, further comprising re-examining the geographic identifier assigned to the addresses and the distinguishing between single-unit and multiple-unit addresses when over-counts occur in the comparison.

19. The method according to claim 13, wherein assigning the segment code includes assigning a first address with a first ZIP+6 code with a segment code associated with a household when only one set of household data exists for the first ZIP+6 code.

20. The method according to claim 13, wherein assigning the segment code includes assigning a second address with a second ZIP+6 code with an averaged segment code when multiple household records share the second ZIP+6 code.

21. A system for market segmentation, comprising:

means for creating a master address list containing a plurality of residential addresses;

means for removing duplicate addresses in the master address list;

means for coding addresses in the master address list with additional geographic identifiers;

means for summarizing the addresses into at least one of the geographic identifiers;

means for comparing the summarized addresses to an estimate from another source; and

means for inserting token records in the master address list when under-counts are discovered in the comparison.

22. A system for market segmentation comprising:

means for creating a master address list coded with ZIP+6 geographic identifiers;

means for assigning a segment code to an address in the master address with a unique ZIP+6 code; and

means for appending the segment code to the master address list.
