   Note: If you are creating a Point Change in Value theme, there will be no sort/subtotal selections to be made.
2. If you selected Color Range or Point Color Range as theme type, do the following:
   1. In the Subtotal Method drop-down list, select your desired method for breaking the overall area into sections. The options are:
      • Equal Ranges: Uses basic division to group the number of areas (rows) equally using the ranges of a specific column of data.
        Note: Depending on the variable and number of ranges selected, some subtotal groups may not contain areas.
      • Equal Geographies: Uses basic division to group the number of areas (rows) numerically. Use this subtotal method to divide your analysis area into an equal number of rows (ZIP Codes, states, etc.), sorted by any column.
      • N-Tile: Distributes the total number of households in an area into groups that are approximately equal, such as fourths or fifths. Dividing data in equal portions ranks the analysis areas by marketing potential, in groups showing the strongest to weakest. This option is available only if you selected Color Range as your theme type.
      • Manual: Lets you customize your subtotal method.
      • Analysis Areas: Groups the records by the selected analysis areas.
        
        If you selected Equal Ranges, Equal Geographies, N-Tile or Manual, specify the number of ranges you’d like included in the theme.
        If you selected Analysis Area, specify how you would like to display and calculate data for each duplicate geography. The options are:
        • Only Once: The report output will not contain any duplicate records (geographies).
        • In Subtotals Only: The report output will contain any duplicate geographies in the subtotals, but not the total.
        • In Totals Onlys: The report output will contain duplicate geographies in both the subtotals and total.
          
   2. In the Number of Ranges text box, specify your desired number of subtotal breaks. You can use the up or down arrow to locate your desired number.
   3. (Optional) If you selected Color Range as your theme type, the Sort Column option becomes available. In the Sort Column drop-down list, select the measure that you want to use as the basis for sorting. The options are:
      • Count: A number based on the selected standard or custom variable.
      • Base Count: The total number of households/population/businesses in the selected extent. The base count will vary depending upon the variable selected.
      • Base % Comp: The percentage of each area’s households/population/businesses compared to the total for all areas.
      • % Comp: The percentage of the product’s households in an analysis area compared to the product usage for all analysis areas.
      • % Penetration: The percentage of customer households that fall within a specified category compared to the total number of households (base count).
      • Index: Compares the proportion of households that fall within a specified category (% Comp) compared to the proportion of all households in the segment (Base % Comp).
