doubling time
Duplication interval measure
Doubling time is how long it takes for something to double in size or quantity.
The term appears most often in contexts of exponential growth—population doubling time, the doubling time of an investment, the doubling time of cancer cells.
At current growth rates, the population's doubling time is about fifty years.
