Ok, first of all I know that there were already thread called population, but it was about concerning quite different subject. I post here some numbers of population of Middle-Earth at the end of Third Age. I have got my informations from finnish LotR forum which was about same subject: http://keskustelu.kontu.info/viewtop...er=asc&start=0 I already posted some numbers in other thread about Eriador's population but now I give you total population of all areas, hope this helps the team members.
Btw, sorry for that this list doesn't include orcs and goblins (Isengard, Mordor, Misty Mts). I would throw as my own guess probably even few millions.
First some human regions.
500 000- 1 000 000
50 000-100 000, might be even little bigger
15 000-25 000,
20 000-50 000
at least 100 000
before Smaug 10000
after Smaug with surrounding areas 1000-5000
10 000-20 000, I always thought only couple hundreds
1000-1500 (human), this has been counted from the number of houses in Bree (Tolkien talked about 100 stonehouses), there have probably lived twice as much in surrounding areas of Bree
200000-500000, if you count Umbar
200000-500000, pretty much same as Harad
Then some hobbit numbers.
50000-100000, Heh, I wonder who came up with this , but maybe it's good guess cause hobbits didn't really die in conflicts and they had lots of children in most of families.
Hobbits of Bree
Let's take a look at dwarves.
In the communities of known Middle-Earth (Erebor, Iron Mts, Ered Luin)
And as the last but not the least elves!
Grey Havens, Harlond, Forlond
Some thousands, probably biggest population, as much as in Rivendell, Grey Havens, Harlond, Forlond and Lothlórien together or even more.
Sorry for bad accuracy in elven populations, but it's a bit harder because Tolkien didn't speak too much about the sizes of elven armies at the end of Third Age.
EDIT: I'm also glad to receive guesses and knowledge about population of Middle-Earth at the end of Third Age.
