Unitarianism is a branch of Christianity and they do consider themselves Christians. They differ from other types of Christians because they do not believe in the idea of the Trinity.
(please note that Unitarian Universalism is a different religious movement, not to be confused with Unitarian Christianity)
Unitarians approach their religious experience by understanding God as one person. In contrast, revivalists believe that God has revealed himself in three persons.
Unitarians, Jehovah Witnesses, and Mormons don't believe in the Trinity.
Unitarians believe in the existence of God, but they emphasize the oneness of God rather than the traditional Christian doctrine of the Trinity. They believe in the unity of God and reject the idea of God as three distinct persons.
Some churches that do not believe in the trinity include Jehovah's Witnesses and Unitarians. Jehovah's Witnesses believe in God as the supreme being and Jesus as his son, but do not believe in the Holy Trinity. Unitarians believe in the unity of God and reject the concept of the Trinity, viewing Jesus as a prophet or teacher rather than a divine figure.
In the 19th century, Unitarians believed in the oneness of God, the importance of reason and individual conscience in religion, and the inherent goodness of humanity. They rejected the doctrine of the Trinity and emphasized the moral teachings of Jesus.
Unitarians believe that Jesus was a good person and prophet, but not God. They also believe the Bible is subject to Human error, and the belief that there is not trinity and that God exists as a separate entity.
There is no specific number to Unitarians. There are big amounts around the world.

Biblical Unitarians believe in the oneness of God and the humanity of Jesus, rejecting the traditional Christian doctrine of the Trinity. They emphasize the importance of following the teachings of Jesus as found in the Bible. This differs from other Christian denominations that adhere to the doctrine of the Trinity, which teaches that God exists as three persons in one essence.
