You can filter the indicator detail page to only display locations within a state, county, region, or service area. For example, if you are viewing an indicator at the zip code level you can filter the page to only display zip codes within a selected location.
You can filter by location by either selecting the "filter" option under the measurement period (see below image) or by selecting a specific location and then selecting the link next to "filter(s) for this location" (see above image).
