How Rare Is It To Reach 100 Years?

It is difficult to accurately calculate the percentage of U.S. firms that are over 100 years old, but I will try. The U.S. census data for 2006 lists the number of U.S. firms at 6,022,000; our data base of companies over 100 years old is now at 540. This would indicate that only .00897 percent of U.S. firms are over 100 years old. We know our data base is incomplete and we add more firms every week, however it appears unlikely that the percentage of companies over 100 years old would approach even half a percent. (Even if the number of firms in our database doubles, the percentage is still just .0179.) Firms that do reach 100 should truly celebrate!

  1. What would be the best way of accquiring a list of companies that are 99 or 100 years old this year?

  2. Unfortunately, there is no easy way to obtain such a list. My data base took hours of work using several sources. Because I started my research a few years ago, I do not have companies founded after 1910 in it or I would be happy to share the information with you. (My student researcher basically scanned Lexis/Nexis and Business and Company Resource Center data bases for the year businesses were founded.)
