The South African population grew by \( 19,8 \% \) between 2011 and 2022 from 51 million to 62 million. Show by means of calculations whether the percentage increase is correct or not.

To calculate the percentage increase, use the formula: \[ \text{Percentage Increase} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100 \] Substituting the population values: \[ \text{Percentage Increase} = \left( \frac{62\text{ million} - 51\text{ million}}{51\text{ million}} \right) \times 100 = \left( \frac{11\text{ million}}{51\text{ million}} \right) \times 100 \approx 21.57\% \] So, the calculated percentage increase is approximately \( 21.57\% \), which means the stated \( 19.8\% \) increase is incorrect! Here's a quirky thought: it seems South Africa's population decided to grow a bit more than expected—like a surprise party that just keeps getting bigger! Population growth can sometimes outpace our best forecasts, just like a cake that rises alarmingly in the oven!
