Simon Kuznets formalised national income measurement for the US Congress

Kuznets set out the modern framework of national accounts in a report to the United States Congress, creating the statistical basis for measuring total national output and establishing the accounting framework that became gross national product and, later, GDP, giving governments for the first time a single statistic to track the scale of economic activity. He simultaneously warned against using the figure as a measure of welfare, a caution repeated in his 1937 section on the uses and abuses of national income measurements.
