I'm not sure if "SA" means South Africa or Saudi Arabia, but South Africa is, according to official reports, at a replacement rate of 2.4 and declining rapidly (down from 6.1 in 1960), and Saudi Arabia is at 2.2 and declining even more rapidly (down from 7.4). Both countries are on the same graph I just linked.
These are graphs of population deaths v. births AKA the "replacement rate" or "fertility rate." In a world were all people who are born live long enough to give birth to their exact "replacements" (a population steady state condition) the replacement rate would be exactly 2. We do not live in such a world, and that rate depends on the rate at which people (babies, children, etc.) die or are reproductively injured before they reach maturity, thus the steady state replacement rate is between 2.1-2.4 depending on the country.
Any population increase graphs in a country where replacement rate is below steady state are based on the fact that people take a while to die. Those graphs level out and then start to decrease as you advance it in time. The UN projects that the world population will begin to decline by 2080 as deaths catch up to the birth rate decline efforts of the past 60 years.
