Single-income families are households where only one adult earns a salary to support the entire family. This structure can arise for various reasons, such as one parent staying home to care for children, a family member being unable to work, or a choice to prioritize family over dual incomes. In these families, budgeting and financial planning become crucial, as the single income must cover all expenses, including housing, food, and education. Many single-income families rely on support systems, such as government assistance or community resources, to help manage their financial needs effectively.
