Americas population growth

[Santiago Araujo]

Hi all, 

I am just researching the future of America's population growth. Trends and shifts in where people are living. What are some resources or strategies BP'ers use to look at, basically, where people are moving. What makes a market a hot market and how do you spot that before it happens. Any insight would be great, does not have to answer my questions specifically, just thought I may open a discussion. Thanks all.
