View In: Map Viewer

Name: Vulnerability Index Block Group 2021

Display Field: NAMELSAD

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description:

The Vulnerability Index is comprised of scores from the following indicators from the American Community Survey 2017 –2021 data.

Low-income Occupations (Population in occupations making only 2/3 of the median income) Table S2401

Low English-Speaking Ability Table B16004

Low Educational Attainment Table B15003

Median Household Income Table B19013

Households without a Vehicle Table B25044

Population without Health Insurance Table S2701

Homeownership Table B25003

Severely Cost-Burdened Renters Table B25070

Methodology: Calculated percent of each variable included in the index, used natural breaks with 5 classes to assign scores of 1 - 5 for each census tract, with 5 being the most vulnerable. Combined scores of all variables to create the index (no weighting was applied).
