The world population reached 7 billion around 2011 (although there’s some guesswork involved). Here’s a video about how we got to 7 billion
More than half of the world’s population has been urban since a few years before 2011. About a billion city dwellers are squatters.
Fertility rates have fallen dramatically over the last several decades, even in many underdeveloped countries, although they remain high in Africa and some of the Middle East. Barring catastrophe, world population will continue to grow for some time. (https://brilliantmaps.com/fertility-rates/)
Here’s what the ecological footprint of more than 7 billion people looks like (https://www.pnas.org/content/115/25/6506). The chart shows estimated biomasses of different categories of organisms, in gigatons of carbon. The biomasses of humans, and of human livestock (mostly cattle and pigs), both greatly exceed the biomass of wild mammals and birds put together. The biomass of wild mammals (terrestrial and marine) is only about 1/6 of what it was before humans came on the scene, and total plant biomass is about ½ of what it was before humans, largely as a result of deforestation.
