Being a geezer myself at 63, there wasn't a lot of company my age or close to it at the 3 meets I competed in last year. Even at the worlds in Vegas. There were 2-3 at the regional meets where 100+ lifters showed up and maybe 4-5 in Vegas where a bunch more competed, I just don't know how many. As the venerable Gordon Santee once said, "At my age, all my competition is injured or dead."
I lift in the USPA but I check the other federations meets for masters lifters and it looks much the same for the others as well.
