        Up as population grows and down as it shrinks.

        Apparently I’m wrong.

          That’s not true. If the population grows only a little, say one more person each year, the relative amount shrinks.

          No. Birth rate has to overcome the collective mortality rate of every year since the first human.

          I don’t know which way is it trending tho.

            It’s trending down as the overall amount of dead humans continues to grow proportionally with the current population. No matter how many humans are born they will eventually die and add to the total; even with a massive and sustained baby boom the ratio of alive humans to dead humans will still, eventually, reach zero.
