Note that this growth is not due to an increase in fertility (or birth rates) but to a decline in deaths.
(2011) World population growth rates between 1950 and 2050. The world population growth rate peaked in 1963 at 2.2% per year and subsequently declined. [8] In 2017, the estimated annual growth rate was 1.1%. [27] The CIA World Factbook gives the world annual birthrate, mortality rate, and growth rate as 1.86%, 0.78%, and 1.08% respectively. [28]
Population momentum impacts the immediate birth and death rates in the population that determine the natural rate of growth. However, for a population to have an absolute zero amount of natural growth, three things must occur. 1. Fertility rates must level off to the replacement rate (the net reproduction rate should be 1). If the fertility ...

These statistics include birth rates, death rates (and hence life expectancy), migration rates and sex ratios.
