|0007547||Dwarf Fortress||World Generation -- General||public||2014-07-21 15:26||2017-12-17 09:30|
|Priority||normal||Severity||major||Reproducibility||have not tried|
|Platform||Windows 7||OS||Windows 7||OS Version||Windows 7|
|Target Version||Fixed in Version|
|Summary||0007547: TOTAL_CIV_POPULATION only affects historical figures, not abstracted populations|
|Description||I generated a medium-sized world for 2048 years with various custom parameters.|
Among those were these:
However, the world_sites_and_pops.txt file contains the following:
Civilized World Population
This seems to be a bug.
|Steps To Reproduce||Generate this world, and then check the world_sites_and_pops.txt file|
|Additional Information||Doesn't seem as bad as in 40.03 where the human population got into the millions. Maybe the bug wasn't fully fixed or it's a different less severe one.|
|Tags||No tags attached.|
|Those pop numbers include generic creatures that are not historical figures I believe.|
|I think the pop cap is intended to limit all civilized beings, not just historical figures.|

I don't think so. The reason for the pop cap is prevent the dataset from getting way too large from all the events and pieces of information attached to hist. figs. It only requires one integer stored to say that there are 100 extra dwarves at a site in addition to any histfigs.
If you look at the number of historical figures alive at any one time during worldgen, you'll see it stays a certain percentage of that number. This tag also only limits civilized histfigs, so often you'll see about twice as many as the TOTAL_CIV_POPULATION as it will include monsters and such.
|Please reopen this if cephalo's comments don't explain things.|
I'm fairly certain that cephalo is incorrect that it only applies to historical figures. The wiki and the in game text don't say anything about about this only applying to historical figures.
According to the wiki:
This determines the maximum possible population of civilization member beings on the map.
Each race may have up to 100 civilizations each, and each civilization a maximum population of 10,000
There are some sites in this world with over 10,000 civilized inhabitants, mainly dark fortresses, to say nothing for the total for those civilizations.
So, I think that this is a bug.

Here's an experiment you can do. Set the TOTAL_CIV_POPULATION tag to 100 instead of 15000. What you'll find is that world gen will go very fast and there will be few historical figures, but the overall civ populations will not be very different for that size world.
There is also the MAX_POP_NUMBER tag in the entity_default.txt file that is set to 10000 for all civs. That means for every civ (not every race mind you) there is a pop cap of 10000. This is the tag that controls overall population and it seems to more or less work. I suppose that number can be exceeded if one civ conquers another etc.
EDIT: If we are all clear on this maybe we should update the wiki.
|The wiki isn't a 100% right manual, you know. I am with cephalo in that, it refers to maximum historical population.|

That experiment only proves that the TOTAL_CIV_POPULATION tag is bugged. I still consider this a bug, as it runs counter to the obvious meaning of "total civilized population"
What it proves is that the tag has an obvious effect on the number of historical figures, but almost no effect on total population. That doesn't mean its broken.
The other tags in the entity raws regarding population strongly imply that populations are intended to greatly exceed 15000. Why specify 10000 per civ? Remember, a large map is set to have 40 civs.
As for the naming of the tag; this may be a fuzzy memory, somebody correct me if I'm wrong, but I believe this tag pre-dates the generic populations, and was added at a time when historical figures were the only creatures generated in civs. So at the time, the name meant what it said, but now is something of a misnomer.
|@thvaz, to be more specific, I believe that the tag refers to maximum historical figures alive at a given time. As they die, they make room for more.|
|Actually it proves neither as it provides evidence for both claims. So I think it would be good to keep this open until we can say for sure.|
|If you think about it, since fortress sieges have to come from existing populations now, you are going to need a lot of goblins. 200k might not be enough to challenge a few long running forts in a world without making goblins extinct.|

After looking through the raws, I believe cephalo is correct; the only bug here is simply that this particular world generation variable uses an obsolete and now misleading name. It definitely seems intended, given the default values and its effects, that this variable is meant to limit the world's population of historical figures rather than total civilized population. Presumably the limit on the number of sites is what is meant to limit the generic civilized population.
As a further example of a similar situation in the raws, world gen also uses SITE_CAP, which, despite its name, does not cap the number of sites but the number of civilized sites, which is what really matters for performance matters. This matter is effectively analogous to this.
