Who was Bernard Bailyn's intended audience of The Peopling British of North America?

Born in 1922, American historian, author, and academic Bernard Bailyn published The Peopling of British North America: An Introduction in 1993 as a prelude to his Voyagers to the West series. Bailyn specializes in the US Colonial and Revolutionary War eras and is a professor emeritus of Harvard College.
The Peopling of British North America: An Introduction is a short work composed of a series of three of Bailyn’s transcribed lectures to undergraduates, with a great deal of footnotes provided. In this book, Bailyn presents four propositions to frame his ideas on why migration from Europe to the Colonies took place. In more recent years, the work has been criticized for its ethnocentric focus and lack of coverage of the effects of this migration on Native Americans and African slaves.
The content of The Peopling of British North America: An Introduction was originally intended for a college-student audience, but the work has also been assigned in high school history courses and has enjoyed a more widespread general readership among those interested in American history.
