This book is fun to flip through, but it's absolutely useless as a research tool, or for anything more than a quick laugh. The main reason for this is that it has no key. The same map of the 209 market areas is used on each page, but the different areas of the map are not identified. Say you've noticed that a small region in the deep south seems to have different "attitudes" than any of the other regions around it, and you want to look up the profile for this region to find out more about it. To do this, you have to guess approximately where in the country the area is (there are no state boundary lines on the map), go to your atlas and figure out which cities are in that general area, and then look in the profiles in the back, which are arranged alphabetically by metropolitan name. The only way to be sure that you've found the right region is to compare the shape of the area to the one on the map. This can be frustrating, especially since there are a couple of regions that have no profiles in the back of the book (I can only assume they were included as deliberate errors to protect the copyright of the maps).
In addition, the book doesn't give any actual numbers; it usually indicates whether a given region has above or below average consumption of a particular product, but doesn't say what the average consumption of that product is.
I understand why the given regions were used (they're the ones marketing analysts use), but for information about the large metropolitan centers of the west this book is pretty useless. Every little town in the southeast has it's own profile, while the LA region includes most of southern California.
Finally, some of the profiles in the back, especially the lists of "what's hot" and "what's not" don't appear to reflect the information given in the maps.
In short, this book is ultimately frustrating if you want to analyze the given information, even casually.
