Notes on the World Population Clock (April 25, 2018):

The populations displayed on the clock are not intended to imply that the population of the world is known to the last person. Rather, the clock is the Census Bureau's estimate of the world population size and an indication of how fast it is growing. According to the current estimates, the world population reached 7 billion in 2012 and the new projections indicate that the 8 billion marker will be reached in 2025. (The Census Bureau’s International Data Base estimates that the world population will reach 7.5 billion on September 19, 2018 at 12:22 a.m. EDT.)

The world population estimates and projections used to produce these figures were developed by the U.S. Census Bureau based on analysis of available data on population, fertility, mortality, and migration. The analysis was performed separately for the countries or areas of the world with a population of 5,000 or more. Population estimates and projections analyses are based on census, survey, and administrative information. For most countries, and especially less developed countries, adjustment of the data is necessary to correct for errors, omissions, and inconsistencies in the data. Since the most recent data for each country are often at least 2 years old (and for most countries they are older), the population figures used for the clock are projections from those estimates based on assumed trends in fertility, mortality, and migration. As new data become available, all data that have been incorporated into the estimation process are re-evaluated and past conclusions may change.

More Stats:

The International Data Base (IDB) was developed by the Census Bureau to provide access to accurate and timely demographic measures for populations around the world. The IDB provides estimates and projections for 228 countries and areas which have populations of 5,000 or more and as recognized by the U.S. Department of State.

This viewer provides four 2018 demographic indicators for the world's countries with a minimum population of 5,000 in 2018: total population, growth rate percent, life expectancy at birth, and infant mortality rate.
