Abstract:This report develops robust estimation models to address data challenges for identifying disadvantaged populations, defined by low-income, racial minority, and limited English proficiency (LEP) status, which aligns with the Virginia Department of Transportation’s (VDOT) SMART SCALE definition. The current reliance on American Community Survey data presents granularity limitations, double-counting risks, and large margins of error, particularly at finer geographic levels.
