Actually, it is well known that reproduction shifts in response to high population density. (e.g., https://www.nature.com/articles/20917 https://www.nature.com/articles/20917, https://link.springer.com/article/10.1007/s00442-019-04337-9 https://link.springer.com/article/10.1007/s00442-019-04337-9, https://www.sciencedaily.com/releases/2000/11/001128070536.htm https://www.sciencedaily.com/releases/2000/11/001128070536.h...). Experimental studies have shown that signals of high density (e.g., playing squirrel calls on loudspeakers) reduce reproduction even when density is not actually high. I would love to test the hypothesis that Instagram exposure of rural populations reduces reproduction independent of education and actual population density.
