arcgis desktop - Recording frequency of names in the attribute table?


I have a question with ArcGIS 9.2. In an attribute table the column [name] includes the name of every place in this layer. Next to that (in columns [numbers]) there should be recorded how often a place of this name is in the map.


How can I calculate this values with VBA in the field calculator?



Answer



I don't know how to do this with Field Calculator, but I do know a workaround.


Run Summary Statistics in ArcToolbox with COUNT on the [name] field. This will create another table where each unique [name] entry will have next to it the number of times it appears in the original layer. Then Join this table back to your original layer, with the [name] field as the link.
