What Does the Vulnerable Population Footprint Mean?

Researchers have identified that educational attainment and poverty are two factors that can have significant influence when it comes to health. When organizations focus their work on improving these two disparities, health outcomes can improve for everyone.

Our Vulnerable Populations Footprint (VPF) tool helps identify areas of a community with specific levels of educational attainment and poverty. Community Commons team member Eloi Espanol breaks it down for us.

How is it Mapped?

After specifying a location, the following information is mapped.

orange  Orange represents a scale displaying precent of population in poverty for a specific area

purple  Purple represents a scale displaying percent of population with less than a high school education for a specific area.

brown  Brown represents those areas in which specific degrees of poverty and educational attainment converge.

 

Annotated VPF

In this case, for instance, brown areas are those in which at least 30 percent of the population is in poverty and at least 25 percent of the population has less than a high school education.

Customizable Thresholds

The threshold values can be adjusted by the user in order to display a customized definition of area.

In the example below, there are now more brown areas that in the previous map because the thresholds have been reduced and now more areas fit the definition created.

The brown areas now represent at least 20 percent of the population is in poverty and at least 14 percent of the population has a less than high school education.

 How is it Interpreted?

The resulting brown areas do not necessarily represent individuals with both characteristics at the same time, but areas which have both defined characteristics independently. As a result, we cannot tell how many people in the area are poor and have less than a high school education.

Imagine a case in which our orange area had at least 30 percent of the population in poverty. Our purple area had at least 20 percent of the population with a less than high school education. The brown areas are defined as having both. If 10 people lived in this area, two realities would be possible.

In both cases, 30 percent of the population is in poverty and 20 percent of the population has less than a high school education, but the distribution of these characteristics is different in each case. This happens because the available data doesn’t allow us to know if an individual has both characteristics at the same time.

Fortunately, there are many data sources that do break down into individual numbers, such as male population or 18-64 years population, and that data for your VPF can be seen when you generate a report.
