How do you research real estate markets?

[Bellman Tumasang]

I know everyone says in order to research and find good markets to invest in real estate you should look at good job growth, incomes, migration etc but how exactly do I find out this info? Do I ask brokers, go to brokerage firms, search online if so what reliable websites because the internet says a lot of things? 

How can I keep up to date with new info on markets?
