Explanation:
If you’re talking about 1% net grown (birth - death), the current world population of 7bn will double in approximately 70 years.
the multiplication factor is 1.01 for 1% growth. If you multiply 7Bn by 1.01 about seventy times, the number is 14bn (double if 7 bn)
(harder but more concrete/compound interest formula):
Cure. Pop * (1+rate)^years = 14
7 (1.01)^years = 14
solving……
years =~70
