On the Side Bar, it is not to be confused with Money because Money is the total amount of $$$ you have, and income is how much $$$ you are receiving each month. The money is in thousands, so if the side bar says you have 500 income, that is equivalent to $500,000. Income is a crucial part of Simburbia. All money you receive is from your income, and with no income you'll fail.
