Population Explorer™ for Public Health

Posted by India Young on August 10, 2018

The field of public health works to promote and protect the health of citizens and the communities where they live, learn, work and play. Those in the public health field work to prevent people from getting sick or injured by promoting wellness and encouraging healthy life choices. Population Explorer helps the public health sector by providing accurate, fast population and demographic data so first responders, epidemiologists, health educators,  public policymakers can retrieve the data they need immediately and effectively. By using the Population ExplorerTM application, those in the public health sector have access to an unequivocal, interactive mapping tool that instantly sources the most accurate, authoritative, and current demographic data available.

Read more about how our data are used in throughout the public health sector.  

Pop Ex for Public Heath

"Population-based routine data provide an important piece of the mosaic of evidence for health policy decision makers. They can be used to assess the magnitude of the health problem, including which populations are most vulnerable; to develop policy goals; and to track and evaluate the effectiveness of health policy interventions" (Morrato et al., 2007).  

Public health workers try to establish living conditions where people can practice healthy behaviors. Initiatives range from conducting scientific research on disease characteristics and interactions with populations, to educating communities about the importance of safe behaviors and vaccines. From implementing safety standards to protecting the public from unsanitary living and working conditions, public health decision makers rely on Population Explorer data to create policies and programs for their region.


Calculating Populations Affected by Disease Outbreaks

Our population and demographic statistics are used across the public health sector to answer demographic questions. For example, responders estimating populations in need of vaccines, treatment, or quarantine use our application to quantify these statistics. From 2017 to 2018, circulating vaccine-derived poliovirus type 2 (cVDPV2) outbreaks were confirmed in Sokoto State, Nigeria as well as the Haut Lomami, Tanganyika, and Haut Katanga provinces in the Democratic Republic of the Congo. Below we see two maps created in the Population Explorer application which compare demographics for the outbreak locations.

The above image illustrates the region where cVDPV2 outbreak occurred. The map shows a density overlay of total children ages 5-9 in the area.

The above image was used to compare population and demographics for other regions affected by the cVDPV2 in the Democratic Republic of the Congo.

Research - Analyzing Populations Affected by Wildfire Smoke

Public health researchers also benefit from using the Population ExplorerTM application. Those studying the effects of man-and-nature driven crises can quickly compare population data with other health variables. Our application offers researchers the advantage of quickly comparing population data with other shapefiles, such as the dispersion of wildfire smoke. For example, one can simply upload the shapefiles showing the spatial extent of wildfire smoke and view the populations affected in these areas. A user can then analyze Population Explorer data output alongside other datasets such as ER visits with a diagnosis of asthma. This will allow for greater prediction of people at risk in those areas.

The above image shows the extent of smoke emitted by the Western U.S. wildfires. Researchers studying asthmatics can compare smoke data with demographics and ER visits.

The above image shows smoke layers uploaded into the Population Explorer application. The user can select each layer to compare the data. 

Public health surveillance is a crucial focus area where Population Explorer data are used to track disease outbreaks and estimate populations in need of aid. Researchers focus on creating policy to protect the public from injury and poor health. Public health advocates work to protect citizens by garnering support for laws and policy. Decision makers rely on Population Explorer data to craft their case and to better inform policies that promote healthy live-work environments, such as creating smoke-free facilities. These advocates are key influencers in the public health sector who apply science-based solutions to health problems built on our data. 


Population Explorer's user-friendly platform is a flexible resource that meets the needs of multi-level users. When you need accurate population data, you can turn to Population Explorer to provide authoritative, global data, instantly and effectively. We are currently offering a free TWO-WEEK trial so you can try the Population Explorer tool for your next project. For memberships, we offer a variety of license types depending on your organization.
