From 1978 to 2018, the human population grew from 4.3 billion people to 7.6 billion people. That's over a 44% increase.

The last 2 years alone, the human population increased by 1.2 billion.

We are currently at 7.8 billion.

1.2 billion people ago was 2006 or 2007.

My maths tell me, an increase of (absolute) 3.3b from 4.3b to 7.6b is a (relative) change of 76%.

My math tells me that 76% is more than 44%. ;D
