700000-2800000 people in 30 years. I find it pretty funny, but lets go with your numbers, cause they are not that unrealistic.
Cause you aren't paying attention to what I am saying I will spell it out for you.
2241 the population of NCR was 700,000 people. In 40 years the area the size of NCR doubled. So that right there doubles the population because more people are made apart of the NCR. So the 700,000 then adds another 700,000 into the fold of the NCR.
Then in that 40 years the population doubles again to get 2.8 million people.
Using evlbastrd's 50 years you still get the samething lets do the math using the population doubling every 50 years.
As of 2241 NCR had 700,000 people. So using 50 years as the doubling mark. 2241-2077 = 164. 164 divided by 50 = 3.28.
So 700,000 divided by 2 = 350, 000. 350,000 divided by 2 = 150, 000. 150, 000 by 2 = 75,000. This means 75,000 people survived the Great Wat of 2077 in Southern California.
Now lets find out the population of 2281. Well as we know it's 700,000 people. NCR doubles its land so that is double the population, so that is 1.4 million. Now the population doubles every 50 years, but its been 40 years so in another 10 years that 1.4 million will double again. So that would put the population of all of NCR around 2.5 million people.
It's HIS MATH! It still works out the same. I said 2.8 million with my math, with his math you still get 2.5 million.
Which fits what I orginally said 3 million people.It's his math and it still comes out to 2.5 million people.
Edit: I am not saying it is for a fact 2.5 million or 2.8 million, but doing a rough estimate given the information we know, such as the 700,000 of 2241 and NCR physically doubling it's territory in 40 years, I get 2.5 to 2.8 million people.
I know there are other factors involved so I will say 2 to 3 million people. So its only 200,000 more than evlbstrd's 1.8 million people and gives a million people margin of error. Given the Math there is
reason to believe it could be as high as 2.8 million people.
