Web9 apr. 2024 · There’s even a simple rule-of-thumb relationship between doubling time and the percentage growth rate: Doubling Time = 72/(Percentage Growth Rate). So that population with a 36 year doubling time, is growing at a rate of 2% per year. But probably the simplest way to describe exponential growth is with a graph, so here’s how it looks: WebRapid population growth is one of the key features of the modern world and provides key evidence for the idea of acceleration.
