How many houses does Santa Claus go to?

Santa visits everyone in the world, but some countries don't believe in Santa, so he does not visit them. Sometimes he uses the countries that don't believe in him as short cuts! I just want to say the website Norad tracks Santa is a great tracker. If you visit on December the 1st, there are games until December the 24th. It's like a countdown until Christmas! Merry Christmas!

(The shorter answer is: All of them!)
