Do the dead outnumber the living?

Do the dead outnumber the living? I think every genealogist wonders about that, because of a phenomenon called pedigree collapse. And, people who believe in reincarnation as it’s usually presented also wonder: there have to be enough dead people for everyone living to have had at least one past life. So, why is the answer so hard to pin down? Over the years I’ve read arguments for both yes and no. After reading this article, I’m still not taking sides.
