The first threshold area includes 9,769 students within 0.8 miles of the Schwarzman Building. The second threshold area includes 39,802 students within 1.3 miles. The third, and largest, threshold area includes 105,449 students within 2 miles. The most precise threshold area ring is the first threshold area, at 98% precision.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559685&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"none\">The threshold areas using the school enrollment variable provide more context to the analysis. There may be policies that each branch must serve a certain amount of people with specifications on how accessible the branches must be for student use. The threshold area analysis could be used for strategic planning for community engagement outreach or travelling library programs such as Bookmobiles. Or, other data variables may be used, such as analyzing households with access to the Internet or computers, to plan resource allocation for public technology availability. <\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559685&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"none\">Threshold areas have dynamic boundaries that encapsulate spatiality based on variables rather than distance or time. As we saw in the two threshold areas documented above, threshold areas change based on the density of the variable. There are less than 10,000 students within 0.5 miles of the Schwarzman Building (the smallest threshold area was 9,769 students within 0.8 miles of the Schwarzman Building), so if a buffer ring was used for this analysis rather than a threshold, the service area would not be as effectively represented. This could result in promoting educational programming to a smaller number of people, resulting in less awareness and even less attendance. Analyzing the characteristics of your service area enables you to better understand the community and create strategies to more effectively serve them.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559685&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"none\">Non-profit organizations, governmental entities, and businesses can use threshold areas to understand their service and trade areas. Other examples include a healthcare non-profit organization using threshold areas to strategize where to place pop-up vaccination stands, or a business with custom sales data mapping its most commercially viable location. There is a wealth of information in the data browser that can be used to enrich the threshold area analysis to provide a contextualized and dynamic portrait of your service and trade areas.<\/span><span
