Due diligence website

[Mary Jay]

A lot of people on this forum are very smart and good at investing. People know which town looses people, where economy is growing, etc... I would like to learn it and was wondering if you please would be so kind and share what websites you use to figure out if population is declining...Or economy in this or that area is growing...

IS there any website that I could get that info from? Thank you guys so much in advance!
