Consistency Principle

Definition

Consistency Principle. One of the three fundamental principles underlying the I-O accounts. Under this principle, the data compiled from one source are comparable with the data compiled from another source. For example, in accordance with this principle, the estimates shown in the I-O accounts should be consistent with the underlying source data and with the estimates shown in the national accounts. In the United States, NAICS provides a consistent basis for classification that enables comparisons across the broad range of economic statistics. The other two principles are homogeneity and proportionality.
