Dive into workers comp data at the classification level with NCCI’s interactive class tree map. The tree map is available to NCCI affiliates, regulators, and independent bureaus.

The tree map allows you to:

  • View data for individual states in addition to the “all-state” view
  • Search for individual class codes
  • See indemnity and medical loss ratios in addition to all of the previously available data types

Watch a video to see how you can use the tree map. You can visualize the impact of the most recent recession and other trends using aggregate payroll, premium, and loss data for more than 500 national classifications. You can also observe changes in several actuarial measures by individual class as well as across groups of classes—and group data by hazard, industry, or schedule.

Put the Tree Map to Work for You

Here are some ways you can make the most of the interactive class tree map:

From the Overview by Year page, view trends in workers comp data across all classes. In this example showing payroll data across all states, you can easily see the impact of the latest recession on workers comp payroll.

To see how these national trends compare with any particular state, use the drop-down menu at the top of the page. There are also drop downs to view other data types (premium, losses, etc.) and to select alternative groupings of classifications.

To drill down on a particular year, click the tree map for that year. Use the mouse and scroll wheel to pan and zoom. The play button and slider at the top right of the screen allow you to cycle through the available years of data with smooth transitions on the graphic.

To return to the Overview by Year page at any time, simply click the title “Interactive Class Tree Map” at the top of the page. There’s also a link back to the Overview by Year in the sidebar on the right side of the page.

You can find individual classifications using the search feature on the sidebar. Click in the search box, start typing a class code, and select your class code from the list that appears. If the class code has data available for that state and year, the map will automatically zoom to its location and momentarily highlight its area.
