Re: A theory on Titans in the Walls (Spoilers)

To be honest I'm pretty surprised those numbers were chosen, because it is no small thing. Also, as
Huesoman suggests in a post before, they manage to ride horses around 1/8 of the second ring in 9 hours (they split into two teams going from west→south, south→west.) I will be using this piece of information to determine the validity of the size of the community. In that case, I'm dishing out references:

http://www.teviscup.org/
Not necessary to click on them, a summary of the links is, medieval knights on horses ≒ 60 miles per day. In current day, special Arab horses for competition's sake do 100 miles in 17 hours (rugged terrain, no baggage.)
Wall Rose's Diameter is (250+130)km x 2 x π ≒ 2300km ≒ 1500 miles. Which means, each of the two teams ride ~190 miles. But they did it in 9 hours, with the last hour slowed down considerably due to nighttime visibility.
Suppose they travel on flat land, and also with this picture (
LINK) showing they didn't exactly start from the south-most part, I would put the estimation at 90 miles for each of the two teams. It isn't impossible, it's double the distance of the "special Arab horses" mentioned above (but unlike the real world Tevis Cup, they don't have to travel rugged terrain.) In conclusion, the SnK community have really really good horses, but that's no surprise because they need them to increase survival rate.
With the Wall-breach horseriding issue calculated, I think the Wall Rose diameter is pretty accurate. Also, even though if it were only for the anime, there had to be communication between Isayama and the staff concerning this information, so I'm pretty confident with the numbers they have given.
Moving onto kkck's point about the availability of territory. I think the problem is, there are only limited number of built towns/communities in Wall Rose. Regardless of how pack the people actually are with the increased population, suddenly (at least) doubling the population would provide serious management issues. Reducing the intake of all civilians within Wall Rose by a half to feed the new population is a lovely thought but not practical. This would throw their economy into chaos, and there is no way the pride and self-interest of Wall Rose citizens would agree to that. We can assume food production within Wall Rose only provides for themselves for the past 100 years, so there is no way they have the resources for a doubled population of what they're supposed to feed. Also, as much as you can tell the people to live off somewhere in the wild away from towns (within Wall Rose,) there is even less chance of finding a sustainable food source enough for the great number of refugees.
Btw, also looking at ImmortalZodd's image, I forgot to mention a very important issue. I don't know if Isayama intends to draw the walls jagged (basically not a perfect circle.) But if the walls really aren't that smooth, please expect the population of Titans within the Walls to
DOUBLE. Lol.
Edit: Actually, with the same picture as posted about (
LINK) you can definitely see the jagged part of the Wall. You can now expect wall-Titan population increase to maybe at least 750 000.
