The benchmark comparisons workflow compares sites using criteria and benchmark values that you define. First, select sites to include in the analysis, and then choose variables and set a benchmark for comparison. The workflow compares your sites—displayed as color-coded symbols on the map—and adjusts the analysis as you change the comparison method or benchmark value. The results of this analysis appear in the Results pane and can be saved as a new layer in your project or exported to an Excel worksheet.
Benchmark comparisons is a guided workflow that takes you through each step: select sites, select criteria, set the benchmark, choose a comparison method, and view and refine your results. For more information on the calculations, methodology, and results of the benchmark comparisons workflow, see Benchmark comparisons reference.
To run benchmark comparisons, do the following:
- On the Maps tab, click Run analysis and select Benchmark comparisons.
The Benchmark comparisons pane appears.
- Select a location type. Choose to add any of the following:
- Click Your sites to use points, polygons, or geographies from your project.
- Use the Add sites window to select from recently used sites, sites currently on the map, sites from any project, or neighboring geographies. Click Apply. Confirm your selections by unchecking the check boxes next to sites you do not want to include in the analysis. Click Add sites to include additional sites.
- Click Features on the map to choose sites in the project or features on the map.
- Use the Select sites pane to select from sites currently on the map or sites from the project. Confirm your selections by unchecking the check boxes next to sites you do not want to include in the analysis. Click Add sites to include additional sites.
- Click Geographies or hexagons to use your country's standard geographic regions (such as states, counties, and ZIP codes) or hexagons.
- Use the Analysis extent search field to define the extent of the analysis by searching for a standard geography. Selecting a standard geography locks the analysis extent to that area.
Note:
Set the analysis extent to the area on the map you want to analyze. For example, to analyze all the counties in Texas, set the state of Texas as the analysis extent.
- If you selected the Geographies tab, use the Level of detail drop-down menu to specify the geography level of the analysis. If you are using U.S. or Esri India data sources, click the Group menu and select a list of grouped geographies (such as census geographies or school district geographies) and choose a geography level to map.
- To refine the level of detail for either geography style, use the Level of detail drop-down menu to specify the geography level or hexagon resolution. For more information on hexagons, including hexagon resolutions, see Hexagons reference.
- Click View glossary to read definitions for each geographic level. The glossary is only available for U.S. data sources.
- Use the Analysis extent search field to define the extent of the analysis by searching for a standard geography. Selecting a standard geography locks the analysis extent to that area.
Note:
You can modify the geography settings at any time in the Geography section.
- Click Your sites to use points, polygons, or geographies from your project.
- Once you have selected the sites for the analysis, click Next.
- Select variables for the analysis from the following options. To view the variables included in a list, click the List button .
- Featured lists—This tab displays a set of curated variable lists, including variable lists by industry.
- My lists—This tab displays variable lists that you created, including variable lists from your previous comparison reports. For these lists, the Share list, Edit list, and Delete list options are also available.
- Shared lists—This tab displays variable lists that are shared with you, including variable lists from your previous comparison reports.
Browse all variables—Open the data browser to search variables or browse by category.
Once you have selected variables, the results are displayed on the map and in the Results pane.
- If you are using sites, use the Sites section to do any of the following:

The statistical measures are automatically added to the Results pane table.
The statistical measures include Average, Median, and Standard deviation.
Note:
If you add average or median, it can be used as the benchmark in the Above and below benchmark comparison method.
- In the Comparison method section, use the Method drop-down menu to select from the following:
- None—No indicators are displayed.
- High to low—This option uses color-coding to display the range of values from highest to lowest.
- Top and bottom—This option highlights the top and bottom ranked values. Choose either the Rank or Percentile option and define the Bottom and Top values.
- Above and below benchmark—This option uses color-coding to indicate if a value is above or below the benchmark. Use the Benchmark drop-down menu to select a benchmark for comparison. Choose either the Percentage or Raw values option as a difference type.
- Quantiles—This option groups the values by quantile. By default, this option uses four quantiles, or you can set the number of quantiles. The minimum number of quantiles is two, and the maximum number of quantiles is ten.
- Highlight extremes—This option highlights values that are defined as extremes, or outliers. Choose either the IQR (interquantile range) or Standard deviation (SD) option to determine how a value is defined as an extreme. If you use standard deviation, you can change the Less than and Greater than values.
Changes made appear immediately on the map and in the Results pane table. See the Comparison method section below for more information.
- In the Style section, do any of the following to stylize the benchmark comparison:
- Use the Color ramp drop-down menu to choose a color ramp.
- Click Reverse order to change the direction of the color ramp.
