Source Table
The Source Table drop-down list contains a list of table names. Choose the table that contains the map objects you wish to redistrict. For example, if one of the tables contains customer information, and you want to assign customers to sales district, choose the customer's table from the Source Table drop-down list.
District Fields
The Field drop-down list contains a list of the columns in the selected source table. Choose the column that MapInfo Pro should use to store district names. MapInfo Pro may not be able to create unique districts if the selected field is less than four characters wide, you will be asked to confirm your choices.
Available Fields; Fields to Browse
The Available Fields list and the Fields to Browse list work together. Available Fields contains a list of column expressions. You can move some or all of these column expressions to the Fields to Browse list. Each column that you move to the Fields to Browse list will appear in the District Browser.

MapInfo Pro builds a district and displays the table in a Districts Browser. As long as the District Browser is on the screen, MapInfo Pro performs districting calculations every time you select or unselect map objects.
- If the Fields to Browse list contains the expression Count, the District Browser displays a count of the number of map objects assigned to each district.
- If the Fields to Browse list contains the expression Fill, the District Browser displays a sample of each district's fill pattern. Also, use the Line and Symbol expressions to include sample line and symbol style in the District Browser.
