What it is:
How it works (Example):
Personal income is used in calculating adjusted gross income (AGI) -- which is important to individuals for income-tax purposes.
It is also an essential measure to investors because it serves as an indicator of future demand for both goods and services in the market. If personal income is high, there could be more money spent in the economy, indicating a future business boom.
Why it Matters:
National personal income levels are very closely linked to the Gross Domestic Product (GDP), and they serve as a key indicator on consumer spending, inflationary pressures, the overall economy and markets.
Income statistics also provide an excellent indicator for socioeconomic disparities and inequalities that could threaten the stability of the economy down the road -- and consequently pose risks for the long-term prospects of the markets.
