I asked Jordi a FAQ question about how large tribal territories would be since this will affect so much at the start of the game and received this answer.

Right now it’s a 100 meter diameter starting tribal territory, increasing 5 meters per additional player. This might be increased. We’ll see how it feels with a few active tribes.
For those who might not know the starting tribal size for claiming territory is 10.
This might be a problem if the game really takes off. 5m per person radius begins to add up to some pretty darn huge area numbers pretty fast once you get a couple dozen people in a village.
Probably shouldn't be a linear relationship. Should be inverse exponential.
It actually is quadratic. If n is the number of members in a tribe (at least 10), then the territory available to the tribe is:

T = pi * (50 + 5 * n)^2 / 4
The division by 4 is due to the fact that Jordi was talking about the diameter, while the surface of the disk is computed with the radius.

From the formula you can see that every new member adds a lot of territory to the tribe. To know better how much more consider this table:

Members | Territory (m^2) | Diff from prev. row
10 | 07854 | n/a
15 | 12272 | +4418
20 | 17671 | +5399
25 | 24053 | +6382
30 | 31416 | +7363
