With the dawn of the 21st century, human presence in orbit around Earth, also called Earth orbit or geocentric orbit has become permanent, meaning that there was not a single day since November 2000 without humans orbiting Earth. At this point the amount of humans can still be given in exact figures:

The current human population orbiting Earth on this page is therefore counted through the following table showing all ins and outs. A location in space near planet Earth is considered to be an “orbit around Earth” if the barycenter of the orbit is permanently closer to Earth's center than to the Moon's center, so not counted for instance are orbits around the Moon or possible future orbits around Lagrange points of Earth. This also means that an orbit further out around the Earth-Moon-system would still be counted.

Table of Orbital Human Activities
The following table gives details on recent activities that changed the number of humans in orbit:

(This list may also be further extended into the past. Please keep it simple.)

Humans on the way to Earth orbit are counted as positive in the column “Changes” at the time reaching their first stable Earth orbit. People in transfer between two stable Earth orbits simply remain counted in total without a new entry line. Once a craft engages into a transfer orbit that is leaving geocentric orbit, it appears as minus in the column “Changes” (no matter it is bound to the ground or to a transfer away from Earth).

Humans on a direct flight from Earth ground to Moon or a Moon orbit will not be counted here, unless the craft went into an Earth orbit in-between (propulsion being turned off).
