The world population increased from 1 billion in 1800 to 7.7 billion today. The world population growth rate declined from 2.2% per year 50 years ago to 1.05% per year.

The Population Projections Program produces projections of the United States resident population by age, sex, race, and Hispanic origin. ACS County-County Migration Flows These files contain the complete county-to-county migration flows by age, sex, race, or Hispanic origin using ACS 5-Year estimates.

The used intercensal single year of age population estimate is adjusted to the results of decennial censuses. So, the time series has to provide the best estimates. 30 Dec 2019 Population growth in the United States crept along at its slowest pace the graying of America, new estimates from the Census Bureau show. 21 Mar 2019 If this estimate holds true, the population of India will surpass China by China's population growth is losing steam because starting in 1994  Weighted-mean ± standard error of the mean (SEM) mark – release – recapture estimates of survivorship, recruitment and the rate of population growth were  19 Apr 2019 ability in demographic rates, allowing estimation of the temporal variance of population growth rate unexplained by density dependence. Life expectancy is a significant factor in estimating the size of the world's populations  This in response to the demands for the latest population estimates at.

In red you see the annual population growth rate (that is, the percentage change in population per year) of the global population. It peaked around half a century ago. Peak population growth was reached in 1968 with an annual growth of 2.1%. Since then the increase of the world population has slowed and today grows by just over 1% per year.

12 Dec 2019 According to current estimates, India's population will peak in the early 2060s at 1.7 billion, putting additional pressure on the environment and  The median estimate for future growth sees the world population reaching 8.6 billion in 2030, 9.8 billion in 2050 and 11.2 billion by 2100 assuming a continuing decrease in average fertility rate from 2.5 births per woman in 2010–2015 to 2.2 in 2045–2050 and to 2.0 in 2095–2100, according to the medium-variant projection.

On the eve of the next decade, Vintage 2019 population estimates show the nation’s growth continues to slow: the U.S. population is at 328.2 million, up 0.48% since July 2018. Growth has slowed every year since 2015, when the population increased 0.73% relative to the previous year. The world's current (overall as well as natural) growth rate is about 1.14%, representing a doubling time of 61 years. We can expect the world's population of 6.5 billion to become 13 billion by 2067 if current growth continues. The world's growth rate peaked in the 1960s at 2% and a doubling time of 35 years.
