As income disparities become increasingly pronounced and economic imbalances grow more evident, evaluating a region's true wealth distribution through a single state's economic performance often provides an incomplete picture. Household income varies significantly across the United States, and a deeper understanding of income distribution can offer valuable insights into different regions' economic models and social characteristics. This report examines the 15 U.S. counties with the highest median household incomes, analyzing their demographic structures, primary industries, median home prices, and price-to-income ratios to reveal the underlying economic dynamics.
1. Somerset County, New Jersey
Situated between New York City and Philadelphia, Somerset County has become a high-income commuter area due to its convenient transportation links. With approximately 350,000 residents, the county boasts a well-educated population—about 50% of adults hold bachelor's degrees.

Analysis & Conclusions
These fifteen counties demonstrate how America's wealth concentrates in specific regions with particular economic advantages. Virginia claims five entries, while California accounts for four—all in the Bay Area. New Jersey's affluent suburbs and specialized hubs like Los Alamos complete the picture.
Common themes emerge: access to high-paying industries (especially technology and government), excellent educational systems, and desirable living conditions. However, the extreme price-to-income ratios in coastal counties raise concerns about long-term sustainability and social equity.
Maintaining these regions' economic leadership will require addressing housing affordability, infrastructure demands, and workforce development—challenges that will shape America's economic geography for decades to come.
