High-income households are defined as families or individuals that earn significantly more than the median income in their area. This income level can vary by location, but it generally includes those in the top 20% of earners. High-income households often have greater access to resources, education, and opportunities, which can contribute to their financial stability and growth. These households typically have higher spending power, allowing them to invest in luxury goods, real estate, and education. They may also contribute more in taxes and have a greater ability to save for retirement. Overall, high-income households play a significant role in the economy and can influence market trends.
