This entry provides an area comparison based on total area equivalents. Most entities are compared with the entire US or one of the 50 states based on area measurements (1990 revised) provided by the US Bureau of the Census. The smaller entities are compared with Washington, DC (178 sq km, 69 sq mi) or The Mall in Washington, DC (0.59 sq km, 0.23 sq mi, 146 acres).
The percentage share of used land that is not arable or under permanent crops. This includes permanent meadows and pastures, forests and woodlands, built-on areas, roads, barren land, etc.
The percentage share of used land on which permanent crops are grown. This is land cultivated for crops that are not replanted after each harvest like citrus, coffee, and rubber. It includes land under flowering shrubs, fruit trees, nut trees, and vines, but excludes land under trees grown for wood or timber.
Largest cities including most recent population (estimates included). Populations are figures only within the city limits, unless otherwise specified. All populations are from 2001 t0 2005 unless otherwise specified.
The name of the CIA World Factbook reference map on which a country may be found. The entry on Geographic coordinates may be helpful in finding some smaller countries.
Continental shelf - the LOS Convention (Article 76) defines the continental shelf of a coastal State as comprising the seabed and subsoil of the submarine areas that extend beyond its territorial sea throughout the natural prolongation of its land territory to the outer edge of the continental margin, or to a distance of 200 nautical miles from the baselines from which the breadth of the territorial sea is measured where the outer edge of the continental margin does not extend up to that distance; the continental margin comprises the submerged prolongation of the landmass of the coastal State, and consists of the seabed and subsoil of the shelf, the slope and the rise; it does not include the deep ocean floor with its oceanic ridges or the subsoil thereof. A full and definitive definition can be found in the Law of the Sea (LOS) Convention.
Population density is midyear population divided by land area in square kilometers. Population is based on the de facto definition of population, which counts all residents regardless of legal status or citizenship--except for refugees not permanently settled in the country of asylum, who are generally considered part of the population of their country of origin. Land area is a country's total area, excluding area under inland water bodies, national claims to continental shelf, and exclusive economic zones. In most cases the definition of inland water bodies includes major rivers and lakes.
Rural population density is the rural population divided by the arable land area. Rural population is calculated as the difference between the total population and the urban population. Arable land includes land defined by the FAO as land under temporary crops (double-cropped areas are counted once), temporary meadows for mowing or for pasture, land under market or kitchen gardens, and land temporarily fallow. Land abandoned as a result of shifting cultivation is excluded.
Capital cities including most recent population (estimates included). Populations are figures only within the city limits, unless otherwise specified. All populations are from 2001 t0 2005 unless otherwise specified.
