Definition
Statistical measures (e.g., Gini Index for earnings, share of earnings held by top percentiles) that quantify the degree of disparity or concentration in earnings within a specific population.
Why It Matters
Provides a precise measurement of how unevenly earnings are distributed. High inequality indicates significant economic stratification, which can impact social cohesion, economic opportunity, and political stability.
Specific Relevance for Professionals:
Marketers
Helps understand the economic landscape for luxury vs. value goods. High inequality might mean a smaller but very wealthy top segment and a larger, struggling bottom segment, influencing market segmentation strategies.
Researchers
Fundamental for advanced studies of economic justice, social stratification, and the impact of labor market trends or economic policies on the distribution of earning power.
Consultants
Crucial for economic development strategies, advising clients on investment in regions with specific earning distribution patterns, and understanding socio-economic dynamics for business planning.
Public Policy Workers
Paramount for informing policies aimed at reducing income inequality (e.g., minimum wage, progressive taxation, education reform), addressing social disparities, and promoting more equitable economic opportunities across the population.
