Given current population trends, overpopulation is becoming less of a thing. China's population declined by a million people last year. That's expected to not only continue, but to speed up. Many countries are declining in population such as Japan and Italy. The US is expected to begin declining in population soon and has mostly been rising because of immigration. It seems that once populations become less rural and more technical, children are less useful to the family. Almost always population levels off and then dips below replacement level. Of course, with all demographics, those numbers can change as conditions change. If there's a societal collapse, population can decline rapidly, for example.

My personal opinion is that it's too late, but I'm a well-known Doomer. I've begun planning for when SHTF just in case I don't die before things get really bad.
