What are Interactive Maps and how do I use them?

Interactive Maps is an online analysis tool that allows for visual exploration of geographic data using a U.S. map and drop-down menus. Color-coding enables quick visual identification of a state by category (e.g. percent). Interactive Maps are available on mobile devices as well as desktop computers and can be easily printed.

Currently, maps allow for state-level geographic analysis of the Treatment Episode Data Set - Admissions (TEDS-A) series beginning with the year 2005. Maps for additional years of TEDS-A, other studies, and other geographic levels are planned for future release.

To begin using the maps, follow these steps:

1. Select the year of data you wish to analyze.
2. Select the substance of interest. Substances are those reported at admission and may have been reported as the primary, secondary, or tertiary substance of abuse.
3. Click the "go" button.
4. Move the cursor over a state to view the count and percentage of the substance at the time of treatment admission.

Several resources are available for assistance while using the maps:

• A color-coded key beneath the map defines the varying degrees of response across the geographic level of analysis.
• Zoom buttons located at the bottom-left of the map allow for zooming in on a geographic area. This is useful when trying to select one of the smaller states or the District of Columbia.
• A map citation is provided for proper documentation of the map.
• A hyperlink beneath the citation provides access to a tabular display of the data.
• The Related Resources section gives quick access to the selected study and series home pages.
