AddressBase Core | 34 522 521 | 31 545 |
Product supply comparison
There is a difference in record counts between taking a national Managed Great Britain Set (MGBS) and the national 5km-tile supply. This is because the two supplies use different selection criteria. The difference in record counts is shown in the following table, allowing you to validate your data holdings once you have loaded the latest release of AddressBase Core.
| Product | MGBS Full Count | National 5km tiled supply | Difference |
|---|---|---|---|
AddressBase Core | 34 522 521 | 34 522 514 | 7 |
A small difference in record counts is expected due to there being several features supplied in the MGBS which fall outside of the tiled area.
Changed records
If you receive a Change-Only Update (COU) supply for your AddressBase Core product, you will receive Insert, Update and Delete records within the supplied file. The following table details the numbers of these records which can be expected in the COU supply of the product:
| Change type | Count |
|---|---|
Inserts | 7 035 |
Updates | 22 671 |
Deletes | 1 839 |
COU populated 5km tile count | 2 586 |
It is important that COUs are processed with Deletes first, then Inserts and Updates. This is to ensure that updates are applied in the correct order. Guidance on this can be found in the working with COU data page in the AddressBase Core Getting Started Guide.
