The world's global population hit 7.5b people today. Probably. According to the UN.

We reached 7b in 2011. Under 6 years ago.

When I was born it was 2.7b

We've had 5 decades or so of constant linear absolute growth. +80m/yr. 12-14 years per +1b.

If business as usual keeps going at this rate, we'll hit 10b round about 2050. In 2015 the UN predicted 2056, but with each 2 year report they revise it closer.

Welcome to the Earth all you lovely people! I hope you brought your tools. She's a fine ship but she needs a good cleaning and climate control is a bit touchy. Also we're a bit crowded so you may have to sleep two to a bunk for a while.
