It is pretty difficult to answer this one because many countries prohibit religious census such as France. Also, many Asatruar are pretty discreet about revealing their faith. We can say roughly that we are 100000 to 300000 in the US, maybe 10000 in Canada, 100000 to 300000 in Europe and 300000 for the rest of the world. We only estimate these numbers from Asatru portals such as Irminsul Aettir.

Their not akin in any way. Atlas was the Titan who held up the sky. In that, he can be assosiated with Tyr, who is said to be the pillar of the sky, or the Irminsul of Anglo-Saxon Heathenry. Or the four dwarves Nordri, Sudri, Vestri and Estri (North, South, West, East), who hold up Ymir's Skull (the sky).

Yggdrasil is the World Tree that connects the nine worlds, with a root in three of them. A branch over every world.

Europe had many different, generally related belife systems. The Ancient Germans (who are not merely Germans in the modern sense but the ancestors of the Dutch, English, Scandinavians...etc...) had many gods. They are most famously known by their Norse names such as Odin, Thor, Balder, Tyr, Yngve-Frey...etc...however the various Germanic peoples knew them by various names, in England they were Woden, Thunor, Bealdor, Tiw, Ing-Frea...etc..their Proto-Germanic forms being Wodanaz, Thunraz, Tiwaz, Ingwaz...etc... General beliefs are the belief in three main levels, that of Gods, of Men and then the undworld, known in Norse as Hel (the English "Hell" is a cognate). Men live on what the Norse called Midgard, and the English called Middengeard, that is the "middle-yard", "middle-enclosure" or "middle-earth". Gods lived in the higher levels called (in Norse) Asgard and Vanaheim (the two sets of Gods being the Aesir and Vanir). They believed in various wights such as type fertility spirit; the elves. In Old English an elf would be called an aelf (where we get the modern "elf") and in Norse an alf. Dwarves were also commonaly believed in as were ettins (or giants if you are that way inclined). Certain trees such as the ash, the oak...etc...were sacred to the Ancient Germans and the worlds were thought to be held together by the world-tree Yggdrasil (possibly the Irminsul of coninental sources). You should read up on it some more...there are thousands of books, documentaries and websites dedicated to this subject.
