How many CEOs are just children, relatives or friends of the founder

If you take companies like Ford or Busch they were taken over by the children of the founders. As a percentage how many companies are run by the children, other relatives and friends of founders?

There was an excellent survey done by The Economist last year on family businesses which you can find here. Let me know if you can’t see the article.

Some relevant snippets:

I distinctly rememeber the article talking about the makeup of successors to a family business but I can’t seem to find in on a quick skim. The closest I could find is:

Extraneous information:

I would suspect a fairly good number, particularly if we’re talking privately owned companies and small-businesses (I would imagine.) Unfortunately, most CEOs that I met were in the young presidents’ organization so still under the “handing over the reigns” age-group–thus I can’t give much in the way of hard numbers or even observed. But in general parents want to see their children fill their own shoes and otherwise have the best chance at success as they can, ergo.

How long it lasts from there will depend of course on how volatile the industry is, and how skilled the progeny. Of course many may also be mostly CEO in title only, with the actual running of the company passed over to others.

Management consultant Peter Drucker says that:

Of course, “family owned” covers a spectrum from small proprietorships where the founder still owns 100% of the business to large corporations where an extended family of cousins owns 51%. And it doesn’t answer your question as to how often a family member is the CEO. I know of no source for that information.
