Is the population growing exponentially?

The world’s human population is growing at an exponential rate. Humans have increased the world’s carrying capacity through migration, agriculture, medical advances, and communication.

What is constant population?

But it also can be described in simpler terms: the growth rate of the population, as a fraction of the population’s size, is a constant. Another way to put it is that the doubling time of the population—the number of years it takes to grow to twice its initial size—is also a constant.

At what constant percent rate of growth did the population increase each year?

The current percentage increase in the human population (as of 2000) is about 1.3\%, or 0.013 per year. If we multiply this, as shown above, by the current population, we get the increase in humans per year: 0.013 x 6.2 B = 80,600,000 new people per year, or 80.6 million new humans each year!!
