Economists sometimes use concentration ratios to evaluate whether industries are oligopolies. In this assignment, you will make your own determination using the most recent data available. You will also discuss the merits and disadvantages of oligopolies in light of your research.

page at the website of the U.S. Census Bureau, click on the PDF of the most recent Economic Census for Manufacturing (NAICS 31-33), and answer the following questions in a two- to three- page paper formatted according to APA style.
