Judaism (a.k.a. the Jewish Religion) is defined as the totality of beliefs and practices of the Jewish people, as given by G‑d and recorded in the Torah (Hebrew Bible) and subsequent  writings of Judaism,  like Halacha etc.
It is an  ancient, monotheistic, Abrahamic religion.
According to the Israel Diaspora Affairs Ministry's statistics, there are currently 14.4 million Jews in the world, with 6.3 million in Israel and the rest spread out over the globe.

Jews believe by definition that G‑d is the single creator and animator of the world.
He has no helpers, no children and no rivals.
Judaism has no dogma, no formal set of beliefs that one must hold to be a Jew. In Judaism, actions are far more important than beliefs, although there is certainly a place for belief within Judaism.

13 Principles of Faith

The closest that anyone has ever come to creating a widely-accepted list of Jewish beliefs is Rambam's thirteen principles of faith. These principles, which Rambam thought were the minimum requirements of Jewish belief, are:

   - G-d exists
    -G-d is one and unique
    -G-d is incorporeal
    -G-d is eternal
    -Prayer is to be directed to G-d alone and to no other
    -The words of the prophets are true
    -Moses' prophecies are true, and Moses was the greatest of the prophets
    -The Written Torah (first 5 books of the Bible) and Oral Torah (teachings now contained in the   
     Talmud and other writings) were given to Moses
    -There will be no other Torah
    -G-d knows the thoughts and deeds of men
    -G-d will reward the good and punish the wicked
    -The Messiah will come
    -The dead will be resurrected
