Create a custom variable
The data browser allows you to create variables that focus on a specific type, range, or combination of data. You can create a variable based on age, household income, home value, housing units, or race. Custom variables are stored in your Saved Variables list.
To create a custom variable, do the following:
- In the data browser, click Create a custom variable
The Create Custom Variable dialog box appears.
Consider these factors when creating custom variables.
- Some variables are not available for creating custom variables, including ACS data variables for U.S. states and the District of Columbia.
- ACS variables for Puerto Rico are available for creating custom variables. Margins of error for these ACS variables are dropped when they are used to create custom variables.
- Some custom variables may not be statistically accurate. For example, calculations are not meaningful when combining adult- and household-based variables or when applying the AVG (average) operator to median variables.
- Click Age variable, Household income variable, or Other popular variables.
- If you selected Age variable, choose a year, age range, and gender for the variable.
- If you selected Household income variable, choose a year and household income range for the variable.
- If you selected Other popular variables, click the category you want to use. Use the slider handles or check boxes to define the variable.
- If you are creating a color-coded map, click Save & Add. If you are using Smart Map Search, click Add.
The Save Custom Variable dialog box appears.
- Create a name for your variable and click Save.
Create an advanced custom variable
You can build a custom variable by selecting variables from different categories and using mathematical operators to combine them. Once created, the custom variable is saved in your Saved Variables list. To create an advanced custom variable, do the following:
- In the data browser, click Create a custom variable or browse to a category and click Create your own 'Category' variable.
The Create Custom Variable dialog box appears.
- Click Advanced custom variable.
- Browse or search for variables in the data browser.
- Add a variable by dragging it into the Assemble your custom variable section or selecting variables and clicking Add Selected Variables.
- Select an operator by clicking it. Choose from the following:
- Standard mathematical operators: + - * / % ^ ( )
- Add Number—Use a constant number in your custom variable calculation. For example, if you want to multiply a variable by 2, click * and then click Add Number and enter the number 2 in the number field.
- Add Sum—Calculate the sum of multiple variables. Drag variables into the SUM field. Click OK.
- Add Average—Calculate the average of multiple variables in your custom variable calculation. Drag variables into the AVG field. Click OK.
- Repeat as needed to create an equation for your advanced custom variable. Build mathematical expressions using parentheses. To reorder items, drag variables and operators in the Assemble your custom variable section. To remove an item, hover the pointer over it and click Remove .
- When you are done, save your variable. If you are creating a color-coded map, click Save & Add. If you are using Smart Map Search, click Add.
- In the Save Custom Variable window, enter a name for your variable and specify the number of decimal places to use for calculation.
- Click Save.
The variable you created is stored in your Saved Variables list in the data browser. You can edit the variable by clicking Edit this variable .
Understand variable calculations
A variable can be displayed as a count, a percentage, an average, an index value, or a reliability estimate. The data browser displays the available calculation options as buttons next to each variable:
If you select Count , the analysis shows the estimated count of the variable in the areas defined on the map.
If you select Percentage , the analysis shows the variable as a percentage value rather than a count. The percentage is expressed as a ratio to a base value, such as total households or total population, and multiplied by 100. For example, the percentage value for the variable Households with an Internet Subscription is the number of households with an internet subscription, divided by the total number of households in the area (this is the base value).
You can view the percent base variable by hovering the cursor over the Info button .
This option is available for variables in the Consumer Spending database. If you select Average , the analysis shows the average amount spent per household annually.
If you select Index , the analysis shows an index value indicating how the amount of the variable in the areas defined on the map compares to another value, such as the nationwide average.
There are three types of indices:
- Index of value—The variable value for the area divided by the variable value for the entire country. For example, the index for Average Household Size is calculated by dividing the Average Household Size value for the specific area by the Average Household Size for the country.
- Index of percent value—The variable percentage for the area divided by the variable percentage for the entire country. For example, the index of Households that Own 2+ Dogs is calculated by dividing the percentage of Households that Own 2+ Dogs in the specific area by the percentage of Households that Own 2+ Dogs at the country level.
- Index of average value—The variable average for the area divided by the variable average for the entire country. For example, the index of Health Care Spending is calculated by dividing the average household Health Care Spending in the specific area by the average household Health Care Spending at the country level.
You can view the index type for a variable by hovering the cursor over the Info button .
This option is available only for American Community Survey variables. If you select Reliability , the analysis shows Esri's reliability score, which is based on the American Community Survey's margin of error (MOE) information for the data in the areas defined on the map. The reliability score indicates Esri's confidence in the estimate, based on the MOE provided. Reliability scores are: high reliability, medium reliability, and low reliability.
