It's hard to be specific because people and being born and dying all the time, but around 7,800,000,000 as of 2020.
Water volume (the total water supply of the world) is 1,338,000,000 km3 which is equivalent to (about):
= 1.338*109 km3
= 1.338*1015 m3
= 1.338*1021 dm3
= 1.35*1021 kg
= 1.35*1024 g water
= 1.35*1024 (g) / 18.01 (g H2O / mol H2O)
= 75*1021 mol H2O
An exact figure is never possible, even when a census is newly completed. However, estimates indicate 7 billion was reached in early November, 2011.

The population of planet Earth is roughly seven billion and climbing. Some scientists speculate that the population is rising too quickly, however there are still many millions of square miles of unoccupied land on our world.
The US Census Bureau reports that the world population estimate exceeded 7,000,000,000 by the beginning of July 2012.
Over 7 billion people inhabit this planet.
At the latest estimate, there were 7.046 billion people on the planet. One mole is 6.022 E23 units, so there is 1.17 E(-14) moles of people.
There are billions of people on Earth. This exact number changes ever few seconds based on births and deaths that are constantly happening.

There are many people who care about our planet. Earth is where we live, and will continue. If we don't care about Earth, how are we going to live?
Earth science is the study of the planet Earth, which includes geology, biology, oceanography and atmospheric sciences, amongst many others.

One - itself. Earth is a planet.
Jupiter is a gas giant planet and has essentially no solid surface so no people could live on Jupiter. If Jupiter were magically a solid planet with earth's gravity, climate and resources but the size of the real planet Jupiter, it cold probably support 100 times as many people as the Earth currently does.
A lot of people. There are an estimated 6.6 billion humans on planet Earth.
The population of the Earth is estimated at roughly six billion people.

This is planet Earth, so one Earth day is one day on this planet.
