What is the term for equality in amount, status, or value?

The term that specifically refers to equality in amount, status, or value is "parity." This word is often used in contexts where two or more items are being compared for equity or equality, such as in financial discussions, comparing statistics, or assessing balance in different dimensions. Parity implies that the items in question are on equal footing, which aligns perfectly with the definition asked in the question.

While "equity," "equivalence," and "uniformity" are related concepts, they don't precisely capture the notion of equality in status, amount, or value to the same extent as parity. Equity generally refers to fairness and justice in treatment or distribution, equivalence focuses on the state of being equal in value or significance, and uniformity refers to the quality of being the same in form, manner, or degree, which does not necessarily imply equality in value or status.
