Which of the following is included in investment income?

Investment income refers to earnings derived from various forms of investments such as interest, dividends, and capital gains. Interest and dividends are the types of income generated from financial assets. This includes interest earned on savings accounts, bonds, or other interest-bearing investments, as well as dividends received from stocks or mutual funds. Both forms of income represent returns on investment and are thus classified as investment income.

In contrast, child support and employment wages are categorized as personal income rather than investment income. Child support is a payment intended to provide for a child's needs and does not derive from an investment activity. Employment wages are compensation received for work performed, not from earning on capital. Tax refunds, on the other hand, represent a reimbursement for overpaid taxes rather than earnings generated through investments. Therefore, the inclusion of interest and dividends under investment income accurately reflects how wealth accumulates through financial resources.
