The number of humans ever born
An interesting demographics exercise\xa0is to add up the number of humans who've existed. This\xa0is different from how many people are\xa0in a population\u2014which in late\xa0November 2022, is about 8 billion. But using data going back as far as possible,\xa0the number of people\xa0who've existed\xa0is reckoned\xa0at over 100 billion.
