Census Concentration Ratio Page

"Concentration Ratios" indicate what percentage of the total business in a four digit SIC code is being done by the largest firms in the industry.

The Manufacturing Census report is called "Concentration Ratios in Manufacturing" and is numbered MC(yr)-S-6 (where yr is last two digits of the census year). It indicates the percentage of business done by the top 4, 8,20, and 50 companies in each four digit SIC code industry. The full 1992 printed report is expected to be available in December of 1996; however, some of the data is already available on-line and we have provided it below. More information about the Census of Manufactures is available at http://www.census.gov/pub/econ/www/mc0100.html. You can read the page and then you can click on "VIEW" in the top left corner to move on into the census.

Similarly the Retail Census has a report called 1992 Establishment & Firm Size Subject Series #RC92-S-1. This report provides information on the size of the companies, sales statistics, employment size, multi-unit info, payroll, and concentration of the largest firms. We have copied the concentration information pertaining to Boat Dealers to our Concentration Ratio Page.

If you try comparing your firm to this data, be sure to use your 1992 figures.

***************************************
Note - their are far fewer companies in the Internal Combustion Engine manufacturing business than there are Boat Builders (250 vs. 2376) and that the Internal Combustion Engine Industry is even more concentrated that the Boat Builder Industry (top 4 companies account for 56 % vs. 32 % of the industry's business).

Note the Boat Dealer industry is far less concentrated than the other 2 industries examined earlier (top 4 firms only account for 3.9% of the business). Also it is very apparent that most dealers only have one location. In the future we may post some "average calculations" with this data. Meanwhile, you might want to go ahead and calculate some of the averages yourself.
