How many Wiccans are there, world wide?? Answer: FIVE MILLION

2004
Wiccans represent a small fraction of the military, roughly 1,500 among 1.4 million active personnel,
https://www.religionnewsblog.com/8314/military-casts-wicca-in-the-shadows
So maybe 0,1% in USA, so 0,3 million or less

57,000 people identified as ‘pagan’ in the UK alone, and some estimate roughly million in the United States. Other sources put the global number at about 3 million.
https://familiarterritory.us/2018/01/20/what-is-paganism/
So, then the global number is 4 times the US number
So then the number would be 1,2 million world wide
that's based on military, so the most serious ones.

As of 2001, the number of Wiccans has grown from 8,000 in 1990 to 134,000. That is a growth of 143 percent! And as of 2013, the number has grown to 200,000 registered Wiccan practitioners and an astounding 8 million unregistered

The 8 million number is very high, but we'll use the growth
number: a factor 2 between 2001 and 2013
Since first number is 2004 we'll use 1,5x growth,
So then we're at 2 million very serious Wiccans world wide

2004
There are between 250,000 and 1 million Wiccans in North America today. A census by Covenant of the Goddess in 2000 came up with a figure of 768,400.

This is a good number from 2004
250,000 to 1 million, so world wide
between 1 and 4 million, that is in line
with our estimation. A confirmation.

2018
several recent studies indicating there may be at least 1.5 million witches across the country
https://christiannews.net/2018/11/21/number-of-witches-rises-dramaticall...
So then the 2018 number would be
4x 1,5 = 6 million world wide
Probably a little too high

Other sources say:

For 2008
In 1990 the US Census estimated Wicca to have 8,000 followers, while Paganism and Spiritualist was listed as “NA”. In 2008, Wicca was estimated at 342,000, Paganism at 340,000, and Spiritualist at 426,000
https://www.jaxpagan.org/education/pagan-traditions/wicca/
That's officially registered
So the unofficial number is higher ...

Pew in 2014 showed
Pew Research Center studied the issue in 2014, discovering that 0.4 percent of Americans, approximately 1 to 1.5 million people, identify as Wicca or Pagan, meaning their communities continue to experience significant growth.

So we can raise our number to 5-6 million indeed,
since the number even grew 2014 to 2018 ...

CONCLUSION

So high, but correct numbers, including
many practitioners

Is 3 million in 2004
And 5 million in 2018
