Population density

"In the days before Pasteur man's population was maintained approximately constant from generation to generation by a cybernetic system in which the principal feedback element at the upper limit was disease. The crowd-diseases — smallpox, cholera, typhoid, plague, etc. — are, by the ecologist, labeled "density-dependent factors," whose effectiveness in reducing population is a power function of the density of the population. No growth of population could get out of hand as long as the crowd-diseases were unconquered, which means that man did not have to sit in judgment on man, to decide who should have a cover at Nature’s feast and who should not." --Nature and Man's Fate (1965) by Garrett Hardin

Population density (in agriculture standing stock and standing crop) is a measurement of population per unit area or unit volume. It is frequently applied to living organisms, and particularly to humans. It is a key geographic term.

Other methods of measurement

While arithmetic density is the most common way of measuring population density, several other methods have been developed which aim to provide a more accurate measure of population density over a specific area.

  • Arithmetic density: The total number of people / area of land (measured in km2 or sq miles).
  • Physiological density: The total population / area of arable land.
  • Agricultural density: The total rural population / area of arable land.
  • Residential density : The number of people living in an urban area / area of residential land.
  • Urban density : The number of people inhabiting an urban area / total area of urban land.
  • Ecological optimum: The density of population which can be supported by the natural resources.
