A capital or capital city is the municipality exercising primary status in a country , state , province , or other administrative region , usually as its seat of government . A capital is typically a city that physically encompasses the government 's offices and meeting places ; the status as capital is often designated by its law or constitution . In some jurisdictions , including several countries , the different branches of government are located in different settlements . In some cases , a distinction is made between the official ( constitutional ) capital and the seat of government , which is in another place . Capital cities that also serve as the prime economic , population , cultural , or intellectual centres of a nation or an empire are sometimes referred to as primate cities . Examples are Athens , Bangkok , Brussels , Copenhagen , Cairo , London , Mexico City , Paris , Lima , Seoul and Tokyo . News media often use the name of a capital city as an alternative name for the country of which it is the capital or of the government that is seated there , as a form of metonymy . For example , relations between Washington and London refer to relations between the United States and the United Kingdom .
Area is the quantity that expresses the extent of a two-dimensional figure or shape or planar lamina , in the plane . Surface area is its analog on the two-dimensional surface of a three-dimensional object . Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape , or the amount of paint necessary to cover the surface with a single coat . It is the two-dimensional analog of the length of a curve ( a one-dimensional concept ) or the volume of a solid ( a three-dimensional concept ) . The area of a shape can be measured by comparing the shape to squares of a fixed size . In the International System of Units ( SI ) , the standard unit of area is the square metre ( written as m2 ) , which is the area of a square whose sides are one metre long . A shape with an area of three square metres would have the same area as three such squares . In mathematics , the unit square is defined to have area one , and the area of any other shape or surface is a dimensionless real number . There are several well-known formulas for the areas of simple shapes such as triangles , rectangles , and circles . Using these formulas , the area of any polygon can be found by dividing the polygon into triangles . For shapes with curved boundary , calculus is usually required to compute the area . Indeed , the problem of determining the area of plane figures was a major motivation for the historical development of calculus .
In biology a population is all the organisms of the same group or species , which live in a particular geographical area . The area of a sexual population is the area where inter-breeding is potentially possible between any pair within the area , and where the probability of interbreeding is greater than the probability of cross-breeding with individuals from other areas . In sociology , population refers to a collection of humans and their entire race . Demography is a social science which entails the statistical study of populations . Population , in a more simple term , is the number of people in a city or town , region , country or world ; population is usually determined by a process called census ( a process of collecting , analyzing , compiling and publishing data ) .
