Accurately determining how much of our economy's total production is American-made can be a daunting task. However, data from the Commerce Department's U.S. Census Bureau and the Bureau of Economic Analysis (BEA) can help shed light on the dollar value of what America produces, and what percentage of the dollar value of an industry's output that is considered domestic. Gross output, value added, domestically-sourced inputs, and domestic content are all concepts that can be used to measure U.S. production and to estimate how much of that production is made in the United States. This book starts with the concept of gross output and then looks further, seeking to answer the question: "What is Made in America?"
