This metric measures the proportion of total income that is concentrated among the wealthiest segment of the population, specifically the top decile. It serves as a crucial indicator for assessing economic inequality, reflecting how wealth is distributed across different societal groups. A higher percentage suggests a significant disparity in economic power, which can lead to social tensions and reduced overall economic mobility. By analyzing this figure over time, policymakers can identify trends in wealth concentration, evaluate the effectiveness of taxation and social welfare programs, and make informed decisions aimed at promoting a more equitable distribution of resources. Ultimately, it provides valuable insights into the broader health and stability of an economy.
