Ground your data with mapping, a quick and powerful way to display summary data or services by location or region. Effective maps can be static and simple, or they can be complex, dynamic, and interactive online objects that enable your stakeholders to compare service providers, schools, programs, performance metrics, and demographics.
Maps Data Considerations
Maps are the best way to quickly convey any kind of geographical or regional data, such as population statistics, demographics, and achievements by region, or to map service providers such as schools, catchment area, Head Start locations, and clinics.
Individual Point Maps
Any noncontiguous geographical data points—e.g., schools and other service providers— are best visualized in individual point maps. The Head Start Locator (Figure 3) is a great example of a searchable service provider map; note that the nodes are color-coded according to what programs are available (red denotes Head Start, and blue denotes Early Head Start).

The polygonal map of Pennsylvania in Figure 4 shows to what extent children are at risk of school failure in each county, based on the Office of Child Development and Early Learning’s Program Reach and County Risk Assessment, 2007-08.

If your map is interactive, include data windows that pop up as a user hovers over a given polygon region or data point. These windows can include the specific numerical data for that point or descriptive information, such as name and phone number of a service provider. Figure 6 from the United States Census Bureau shows the percentage of children under age 5 living in poverty in 2016. Hovering over each state provides the state estimate and confidence interval. To use the interactive features, visit the Census Bureau website.
