The density of water is 1.0 and people are made mostly of water but they do float in water (just) so the density of a person is lust less than 1.0.
I can not give you a precise answer because of cause your density would change as you breath in and out.
Since the average person is predominantly made up of water, we are very close to the density of pure water - which is why we just barely float in Swimming Pools, hot tubs, etc. When you fill your lungs with air you float better, when you expel air, you start to sink. According to a 1966 study by the US Army (see the attached link), the average density when as much air as possible is expelled is about 1.062 g/cm3. Of course we don't go around with our lungs empty all the time, so most of the time our average density is less. People with more fat tend to be slightly less dense than people who have very low body fat. About 1% of all people are so lean that they will actually sink completely when placed in fresh water even without exhaling all the air they can.
Within all the variability posed by these factors, a reasonable estimate would be that the average person, fat and all, with their lungs inflated, has a density between 0.924 g/cm3 and 0.957 g/cm3. That averages out to about 0.94 g/cm3.
I am not sure......but I know some that are pretty dense
Slightly less than 1
Salt water has higher density than the body of a person who floats on it, but the person's body may sink in less dense fresh water.
DENSITY : density is the ratio of mass and volume of the substance density=mass/volume RELATIVE DENSITY : It is the ratio of density of a substance to the density of water
relative density is related to the density of water. i.e. a relative density of 19.3 means that it has a density 19.3 times the density of water. The density of water is 1g/ml therefore the density of gold is 19.3g/ml
The person's body does not change density, but when you put a life jacket, you and the jacket can be modeled as one object. The life jacket itself has a very low density, much lower than that of a human. So, when you put on a life jacket, you effectively increase your volume, while mass increases by a much smaller degree. As a result, net density decreases.

A person's body frame is determined by the weight and density of a person's bone structure.

what do you think the person density in the persons body might be?
Uruguay:Population - 3,463,197Population density - 51.251 person per square mile
1 kilometer per person
About one person per square mile.
12.5g/cm3
The density of the human body is brought down by the lungs, which contain air.
