Lets take a quick look at some of the details of a Level 1 profile.
Looking at the left map, you can see pockets of customers in large metro areas and very few in rural areas.
The second map shows more even distribution from rural to urban, but a high concentration of customers on the coasts (this happens to be higher income areas).
The most important point is that each customer or prospect sample has a unique fingerprint. Even in extremely small populations (i.e. less than 10,000). The patterns still emerge. They are readable, understandable and make sense.
Seeing your data is the first step toward understanding your data.
