It varies from person to person and with the position the person is in at the time. For a person standing upright, it's usually somewhere in the vicinity of the navel.

The center of gravity is the theoretical point where all the body weight is concentrated or the theoretical point about which the body weight is evenly distributed. If a body is of uniform density and has a symmetrical shape the center of gravity is in the geometric center. If the object is not symmetrical and does not have uniform density, it is more difficult to describe the location of its center of gravity.
The center of gravity of a solid body does not always lie within the body. An example of this is a hula hoop. The center of gravity does not lie on the hoop that rotates.
The human body is bilatertally symmetrical because the left and right halves of the body mirror each other, as you can see in the image to the left.as such the centre of mass of the human body should lie in its geometrical centre of the bodyIn most people the center of mass is around the belt buckle andabout 4" in. A Japanese martial arts instructor could be used to show you where the "hara" is. This approximately the same location.
That "point" in a body where the entire weight of the body can be represented to be present. Extend your knowledge by exploring where the center of gravity would be for metal shapes formed in the shapes of circular, square, rectanglar, hexagonal rings with metal rods. Where would the center of gravity be, on the ring or outside the ring?

If you want to define total centre of gravity of a person, you must know:the mass of each body segmentsthe x, y and z coordinate of centre of gravity of each body segment (3D motion)

If the gravity is not constant over the body.
if you stand with your feet evenly apart, directly between both your legs is your center of gravity.
No. For example, a ring has a center of gravity in the center of the ring, not on any part of the ring.
yes ,when centre of gravity and center of mass is at a st.line the body is balanced.

Center of gravity is supposed to act at the centroid of the body. while center of buoyancy is the center of gravity of fluid displaced . so they cant be at single point. if the body is completely submerged and homogenous then both cg and cb will coincide
