The HDI is a composite 0–1 score published annually by the UNDP, combining life expectancy at birth, mean years of schooling and gross national income per capita. Scores above 0.800 = Very High Development; 0.700–0.799 = High; 0.550–0.699 = Medium; below 0.550 = Low. Market analysts and strategic planners use HDI to evaluate workforce quality, consumer spending capacity and operational infrastructure maturity when assessing United States as a target market or investment destination.

GDP per capita and unemployment rate are two of the most reliable indicators for evaluating consumer market potential.
