There was growth to 1950 and then it remained the same or declined. The birth rate is adding to the total population but as a factor on it's own it is declining - Population growth in the US is partly new births and partly people moving to the US from other countries.
Total world population growth rate is driven by new births entirely (unless you think shape shifting lizards have moved on-planet...) and that rate is declining. It is still adding to the population but at a slower rate.
