Answer 1

Do your own homework.

Answer 2

Up to date numbers are difficult to come by, but in 2001, 1.1 billion people lived on less than $1 a day.

How much to help them is a loaded question.  Does helping them mean feeding them?  Educating them?  Providing homes?  Relocating them to places where their governments won't oppress them?  Overthrowing those governments?

Homelessness is a less rampant problem.  As of 2005, there were around 100 million homeless people around the world.  Obviously, that number changes daily, especially with catastrophes like the earthquake in China.
