Income groups categorize individuals or households based on their earnings. These groups typically include low-income, middle-income, and high-income brackets. The classification helps in understanding economic disparities and the distribution of wealth within a society. Governments and organizations often use income groups to design policies and programs aimed at addressing issues like poverty and social inequality. By analyzing data from different income groups, they can tailor support services, such as education, healthcare, and housing, to meet the specific needs of each group effectively.
