Income growth refers to the increase in an individual's or household's earnings over time. This can occur through various means, such as salary raises, promotions, or additional income sources like investments or side jobs. Tracking income growth is essential for understanding financial health and planning for future expenses. Factors influencing income growth include education, job experience, and economic conditions. Higher levels of education often lead to better job opportunities and higher salaries.
