what is population density mean????

Population density is a measurement of population per unit area or unit volume. It is frequently applied to living organisms, humans in particular.\n\nyou may want to check this site:\nhttp://en.wikipedia.org/wiki/Population_density\n\nsite also contains methods for measuring population density

p = number of adults\nc = number of children\n\nthen there are p-c more adults than children

Population           = Ranked 46th\n- Total (2004 est.)  = 138,400\n- Density            = 364 / km²\n- District           = Ranked 125th \nEthnicity:             98.7% White

density = mass/volume.\n it changes wt respect to temp.\n as temp increases,volume increases and so density decreases. however there may b some exceptions.\n  as an example, if v heat water to high temp but less than it's boiling point, it's volume increases.\n  so, v can say that the density is less than the previous condition.

Maybe this explanation can help? http://en.wikipedia.org/wiki/Spectral_density

Density is the mass per volume.  Buoyancy is the comparison of an object's density with the density of the surroundings.  Helium balloons rise being lifted by the surrounding air sinking around them.  They are less dense than the air they displace, hense are buoyant.

It means "about" or "roughly."\n\nFor example:\nThe world population is ~6.5 Billion.\n\nOnline it's used for lots of things, including making decorative section breaks, such as this:\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nIf it's on top of a letter, such as with "ñ" or "Ñ," then it's an accent mark. (FYI - you can make these characters by holding the "Alt" key while entering the numbers "164" or "165," respectively.\n\nHope this helps.

If you have 100 ppl living in 1 sq mile they have less room then 100 ppl living in 100sq miles, same population but the 1 sq mile ppl are more dense then the 100sq mile ppl. I hope that helped. Great Question though.

Sample means you only obtain a part of the data.  Population means you obtain all of it.  When calculating sample standard deviation you divide by one less that the number in your sample; population S.D., divide by the full number in the population.

We are not under populated. Land or size of a country has nothing to do with a country population it is the resources that is needed. We are running out of water and areas that can sustain population. \nIt is call "Carrying Capacity" look it up you just might learn something. \nAlso, the USA is losing a quality of life do to over population. 300,000,000 at a 1.25 rate of growth. Traffic, smog, the in ability to fix roads, educate children, health care you name it we are losing everything. Those are the things that made this country the best place to live and we are losing it fast.

Take a deep breath.  The average density of a human is 61-67lbs/ cubic foot, but this drops to 56-62 lbs/cu foot if you inhale.

it is unclear what you mean when you say that a population is increasing from 0 to 30. is it a finite poulation? do the items in the population take values from 1 to 30? As you have asked it, this question is impossible to answer.

I'm not sure what you are asking.  The number of people?  The kind of people?  or ????

It means an abundance of.

look at column 7.  all of the densities appear there in grams/cm3.\n\nhttp://www.science.co.il/PTelements.asp

I've also heard of studies similar to those you're referring to; I agree 100% w/ you that high population density is a pretty feasible reason for homosexuality and violence, these may well be nature's "control mechanisms" for avoiding LOCAL overpopulation. As far as the whole world being overpopulated, I don't agree w/ you.... food production nowadays, for example, could feed more than 100% of the world's population adequately if equally spread among all human beings; furthermore, global birth rates are rapidly declining, which could actually lead to global UNDERpopulation just a few centuries from now.

the equation used to determine density is\nD=m/v \n"D" means density\n"m" is mass\nand "v" is volume of the object.\nmass is the total amount of paritcles something has.  Think of the old trick question: Which weighs more a pound of feathers or a pound of lead.  The answer is they *weigh* the same.  However, now think about how much lead you would need for a pound of it and how many feathers.  Little lead, lots of feathers.  Basically the more matter in a smaller space means higher density.  I really hope this helps.\n\n\nJust thought of another example:\n\nTake 50 pennies.  Put them in a big ziploc freezer bag, press out all the air and zip it shut.  Now, take another 50 pennies and put them in a penny roll--like you see at the bank.  Same amount of matter, 50 pennies.  But they are less densley packed in the bag because the volume of the bag is bigger than the volume of the roll.
