Measuring Human Capital addresses a country's most important resource: its own people. Bettering human capital benefits individuals and their country and leads to improved sustainability for the future. For many years economists only used Gross Domestic Product (GDP), now acknowledged to be inadequate without supplemental measures, to gauge a country's overall value. There is now a recognition that many variables contribute to a country's worth, which make accurate measurement difficult. Looking beyond GDP by focusing on human capital, researchers, policymakers, government officials, and students can understand what elements impact human capital and how they might improve it in order to increase economic growth and well-being.
