37. There's a website that tracks the world's population in real time. As of 2019, the overall human population is estimated to be more than 7.7 billion people. And if you want to watch that increase in real time, you can tune into the World Population Clock, (https://www.worldometers.info/world-population/) which shows the upticks and downticks as babies are born and other people die. You can also see the current populations of different countries, including China (1,420,000,000+), India (1,368,000,000+), and the U.S. (329,000,000+).
