Making a Map

Updated 9 months ago by PolicyMap

Search the Map

To start, you should specify a location. The location box above the maps allows you to quickly find and position the map to different places.

  • By Location – The default search is by Location, so enter an address, city, state, zip code, etc in the entry box and hit Enter/Return on your keyboard or click the magnifying glass icon.
    • If searching by a type of geography, like Philadelphia, you will see the map position itself at the location you entered, with a border surrounding the geography. If more than one location in the US has the same name, the map will default to the largest populated location, and a box will appear listing all matching locations by population.
    • If you are searching by an address, the map will zoom to the address and drop a pin.
  • By Pre-Defined Geography – Use the drop down menu in the Location bar to search for specific geographies. For example, if you want to find a specific census tract, start by selecting Census Tract from the drop-down menu. Simply enter the FIPS code for the tract and hit Enter/Return on your keyboard or click the magnifying glass icon.

Viewing the map – You can zoom in and out by double-clicking the map, using the scroll wheel on your mouse, or using the +/- buttons in the bottom right of the map. To pan the map, select and hold your left mouse button then drag the map within the map window.

search for data

The Search Data field allows user to use keywords or a grouping of words to find the data that is available on PolicyMap.

  • The top of the results bar will show the total number of matches for the keyword. If the results do not match the data you are looking for, try to add additional words or specific keywords.
  • The results will show the data title, where to find the data in the category, and the source of the data. Mouse over the icon to see the data description.
Adding Data from Categories

Select a category and navigate the menu to the indicator to add the map.

  • Data Description – Select the "information" icon to see a full description of the data layer.
  • Source - Select the source name to find more information on where the data came from and details about the data source.
  • Year – Depending on the data layer added, you can toggle between available years, quarters, and months. Some years are only available to subscribers and trial users.
  • Variable – Changing the variable will change how the data is displayed on the map. You can toggle between different variables, including the number, currency, percent, or even the change across years.
  • Color - Change the color of the data layer shading.
  • Shade by– PolicyMap displays data at different geography levels. How far you are zoomed in determines what geography the map is shaded by default. For example, when looking at the nation, data is shaded by state. As you zoom in, shading might change to the county, zip code, census tract, and finally block group level.
    • Use the lock icon to prevent Shade By from changing as you zoom in and out of the map.

Select the color range in the legend to isolate a range or multiple ranges on the map.

Data Points Customization

Data Points allows you to view point datasets, like addresses, on a map. You can view these datasets by themselves or on top of a data layer.
