lower. the air pressure is lower the higher up you go (think about all of the air above you pressing down on you - the higher up you go, the less air there is above you), so the molecules can space themselves out more.

USA Vol. 95, pp. 14009-14014, November 1998 Applied Physical Sciences, Social Sciences ABSTRACT The global distribution of the human population by elevation is quantified here. As of 1994, an estimated 1.88 X 10^9 people, or 33.5% of the world's population, lived within 100 vertical meters of sea level, but only 15.6% of all inhabited land lies below 100 m elevation. The median person lived at an elevation of 194 m above sea level. Numbers of people decreased faster than exponentially with increasing elevation. The integrated population density (IPD, the number of people divided by the land area) within 100 vertical meters of sea level was significantly larger than that of any other range of elevations and represented far more people. A significant percentage of the low-elevation population lived at moderate population densities rather than at the highest densities of central large cities. Assessments of coastal hazards that focus only on large cities may substantially underestimate the number of people who could be affected.

That is ... the higher you go the less dense the air.

How does altitude affect density and air pressure?
Altitude has a large affect on the air pressure and air density. Air density reduces with altitude and air pressure reduces with altitude as well.
What condition is pressure altitude and density altitude the same value?
At standard temperature.
Is air pressure decreases so does air density?
Air density decreases with altitude, warmer temp and moisture
What is the relationship between physical density and the refractive index of an inorganic solution?
density affects the speed of light in a substance the higher the density the slower is the speed and vice versa
What effect does high density altitude as compared to low density altitude have on propeller efficiency and why?
Efficiency is reduced because the propeller exerts less force at high density altitudes than at low density altitudes. Less efficient slow plane
What is difference between altitude and density altitude?
"Density altitude is the altitude in the International Standard Atmosphere at which the air density would be equal to the actual air density at the place ofobservation". See the related link.Atmospheric density corresponds to the distance from earth's gravitationalcenter, whereas altitude refers to the vertical distance from a set point on earth's surface.Worth noting is the fact that temperature and humidity are factors in air density, and must be adjusted for to give an accurate density altitude.
When altitude increases does air density?
The density of the atmosphere decreases with altitude.
What is the Relationship between relative density and density?
the relation between relative density and density is that relative density of a substance is its density itself without its unit.
What is density altitude?
Density Altitude is the altitude relative to the standard atmosphere conditions (ISA) at which the air density will be equal to the indicated at the place of observation.
How does density of the air change with altitude?
The density of air decreases when the altitude rises.
What is the relationship of oxygen density to altitude?
As the altitude increases, the density of oxygen decreases.
How does altitude affect density and air pressure?
Altitude has a large affect on the air pressure and air density. Air density reduces with altitude and air pressure reduces with altitude as well.
Does the density of the air increase as altitude increases?
The density of air decreases with increasing altitude.
How does substance's density affect its boiling point?
A relation between the boiling point and density doesn't exist.
How is density and altitude related?
They are relted because as the altitude increases than the density will alwways decrease.
How does altitude affect the density and pressure of air?
Altitude affects density and pressure by decreasing when it increases.
What is the relation between altitude of a base cloud and the temperature of the air at that altitude?
The base of the cloud occurs at the dewpoint temperature of the airmass. See: http://www.csgnetwork.com/estcloudbasecalc.html
