Q. Who is the wealthiest Ann Arborite?

A. That’s not easily determined. It is difficult to obtain information about personal assets and debts, and valuations change constantly. Forbes makes the effort for billionaires and reports that the only billionaire living in Washtenaw County is Bill Young. Described as an Ypsilanti resident, he’s cofounder and CEO of Plymouth-based manufacturer Plastipak; at press time, Forbes estimated his net worth at $2.3 billion.
