{ "currentVersion": 10.91, "serviceDescription": "This web service contains the 2020 Vulnerable Population Index (VPI) along with the component demographic layers. The following seven populations were determined to be vulnerable based on an understanding of both federal requirements and regional demographics: (1) Low-Income Population (below 200% of poverty level), (2) Non-Hispanic Minority Population, (3) Hispanic Population, (4) Population with Limited English Proficiency (LEP), (5) Disabled Population, (6) Elderly Population (age 75 and up), and (7) Households with No Car.For each of these populations, Census tracts with concentrations above the regional mean concentration are divided into two categories above the regional mean. These categories are calculated by dividing the range of values between the regional mean and the regional maximum into two equal-sized intervals. Tracts in the lower interval are given a score of 1 and tracts in the upper interval are given a score of 2 for that demographic variable. The scores are totalled from the seven individual demographic variables to yield the Vulnerable Population Index (VPI). The VPI can range from zero to fourteen (0 to 14). A lower VPI indicates a less vulnerable area, while a higher VPI indicates a more vulnerable area.FIELDSP_PovL100: Percent Below 100% of the Poverty Level, P_PovL200: Percent Below 200% of the Poverty

This web service contains the 2020 Vulnerable Population Index (VPI) along with the component demographic layers. The following seven populations were determined to be vulnerable based on an understanding of both federal requirements and regional demographics: (1) Low-Income Population (below 200% of poverty level), (2) Non-Hispanic Minority Population, (3) Hispanic or Latino Population (all races), (4) Population with Limited English Proficiency (LEP), (5) Disabled Population, (6) Elderly Population (age 75 and up), and (7) Households with No Car.<\/SPAN><\/P>

For each of these populations, Census tracts with concentrations above the regional mean concentration are divided into two categories above the regional mean. These categories are calculated by dividing the range of values between the regional mean and the regional maximum into two equal-sized intervals. Tracts in the lower interval are given a score of 1 and tracts in the upper interval are given a score of 2 for that demographic variable. The scores are totalled from the seven individual demographic variables to yield the Vulnerable Population Index (VPI). The VPI can range from zero to fourteen (0 to 14). A lower VPI indicates a less vulnerable area, while a higher VPI indicates a more vulnerable area.<\/SPAN><\/P>
