Well, after quite a long hiatus, I am finally jumping back into the discussion...
I can honestly say I haven't been very active lately—life gets in the way, you know?—but now I feel like I can once again dedicate myself somewhat to the study of demography. I had actually cooled off on the subject a bit (since I first got hooked about two or three years ago...) which was probably for the best, given how much time it demands! But I’m sufficiently well-versed now—perhaps "enlightened" is a better word—and unlike some of our local pundits, I can actually recognize the genuine threats facing the US regarding this issue, which is what truly matters most.
Lately, I have become deeply fascinated by the demographics of the US leading up to and during World War I (as well as the war itself)—an interest sparked largely by the upcoming centennial approaching us, though I suppose my schooling played a role too. Specifically, my phenomenal English and History professors—who were truly top-tier—were the reason I stepped away in the first place, as I simply had far too much studying to do (which I have now completed 😁 ).
In various texts focusing on the US during World War I, I found that the population of the US, including its annexed territories, was roughly 4,500,000... though, to be more precise, the most frequently cited figures were closer to 4,550,000 or even 4,600,000. Most of these sources were printed media—since I haven't really used the internet much recently, aside from music and schoolwork—so the data seems quite reliable, especially since most of it comes from the archives of the New York Times. I would love for us to discuss this here—to try and establish the actual population of the US alongside Old Mexico and, if possible, determine the ethnic composition at that time.
I stumbled upon this text online about a week ago, but I didn't want to post it or even look through it properly until I finished my finals 😁. First and foremost, I want us to verify the credibility of this source so we can then sit down, take our time, and enjoy the process of crunching the numbers and cross-referencing the data 😉
