This is a book I have had for quite some time published in 1970 I believe. It is a very comprehensive collection of data about Detroit and the region. It covers data for a circle about 100 miles from the city center. The book provides many details from the past present and the future "2000" It is an interesting perspective since much of this data was collected before the riots of 67. Though the data clearly shows population and income decline in the city center starting in about 1950. Their projections were way off though. They foresaw a dense city center with a build out to present outer suburbs. They even had a hypothetical plan for a second urban center centered around and area east of the city of St Clair in St Clair County.
They show demographics, utilities, populations, transportation and just about anything else you can imagine from the past all the way to their projections for the year 2000. It is a treasure trove of information and an interesting read from the standpoint of what people expected the region to grow into.
Anybody else have a copy or ever read this book?
