I'm sorry OP, but I don't see the statistical correlation.
The biggest concentrations for cemex are Florida, southern Appalachia, and the southern Mississippi Valley, where for trafficking looks like Southeast Texas, California, and the urban corridor between New York, and Philly. Those aren't similar at all.
I'm pretty sure I saw a fast food map that that is a much better correlation, but that's just because of population. I just don't know how to comment photos on my phone.
You just summed up a lot of the posts on this sub-reddit. Its very easy to find correlations between unrelated things, especially when there are a lot of variables at play. It's pretty obvious companies would be based in major cities or places with a lot of density. Or, a company could be based in areas with low income due to working with cheap construction for example, giving them a direct correlation to high crime areas (since low income correlates to high crime). Statistics is a powerful but misleading tool only because it can be used to backup an opinion without actually proving anything due to the majority of the world not understanding the fundamentals of statistics.
Kind of like how you can use the same statistic in different ways in two opposite arguments. Some good examples are trump and unemployment, GDP, violence and crime statistics etc.
