According to the 2008 American Religious Identification Survey, there are about 2 million US adults that call themselves agnostic.
This number is debatable, however, as different definitions would lead to different numbers calculated.
It's also possible that some people answering the survey were agnostic, but chose not to declare themselves as such due to the stigma attached to not professing belief in a god in the United States, as well as due to the aforementioned varying definitions.
31.4%
There is no recognized 'leader' for agnostics. However, a fair number agnostics are also interested in secular reasoning and philosophy, so many of the great philosophers of the ages (Socrates, Hume, Kant, Descartes) are read and debated by some agnostics. There are also a number of vocal agnostics/atheists who are in the public limelight a great deal, including Richard Dawkins.
Agnostics by their nature dont believe in anything as they feel they are not equiped to understand reality./
There are about 30% of the people in Wales that are Agnostics.. That is up from a 2001 survey when only 15% where considered Agnostic. Although to have an accurate percentage is difficult to measure because people can change their mind at any time.
Agnostics do not believe anything about God. Agnostics do not believe in any type of religion.
Atheists/Agnostics/Non-Religious. Constitute around 10% of US population. No representation.
Protestant, Catholic, Islam, Buddhism, Wicca, and many other religions, agnostics, and atheist.
Although no records on religion are kept (to do so would violate US federal law), it is safe to assume that Jews, Christians, muslims, atheists, agnostics and many others own shares of Tesco.
All countries.
That isn't a simple question to answer. Not all agnostics necessarily believe the same things. So, some do, some don't.
You seem to be lumping all agnostics together into one uniform mindset. The reality is that agnostics, like in almost any group of people, all have their own separate thoughts and opinions. So I'm afraid that your question really doesn't have much of an answer.
They can be either Atheists or Agnostics.
