In today's weekly edition of Louisville Business First, you'll find our list of the area's wealthiest ZIP codes. And we have another report that looks at some cool numbers from the data we gathered for the list. I always like looking at this list, comparing factors such as home values, household incomes and even populations. The information is provided by Esri, a Redlands, Calif.-based research company. But, of course, there's only so much information we can include in the paper.
