How many people worship the Greek gods and goddesses?

In modern day Greece, as of 2005, it is estimated that there are 2000 people who practice Hellenic neopaganism. There are an additional 100,000 people who have 'some sort of interest.'

Outside of Greece, there aren't very many hard numbers. In the United States, the organization Hellenismos, which promotes Hellenic worship, only claims about 50 members. The religion is not large enough to be counted on the U.S. census, nor on the U.K. census.
