Definition

Total
population

De facto
population in a country, area or region as of 1 July of the year indicated.
Figures are presented in thousands.

Urban
population

De facto
population living in areas classified as urban according to the criteria used
by each area or country. Data refer to 1 July of the year indicated and are
presented in thousands.

Rural
population

De facto
population living in areas classified as rural. Data refer to 1 July of the
year indicated and are presented in thousands.

Percentage
urban

Urban
population as a percentage of the total population.

Percentage
rural

Rural
population as a percentage of the total population.

Average
annual rate of change of the total population

Average
exponential rate of growth of the population over a given period. It is
calculated as ln(Pt/P0)/n
where n is the length of the period and P is the population. It is
expressed as a per cent.

Average
annual rate of change of the urban population

Average
exponential rate of growth of the urban population over a given period. It
is calculated as ln(UPt/UP0)/n
where n is the length of the period and UP is the urban population. It
is expressed as a per cent.

Average
annual rate of change of the rural population

Average
exponential rate of growth of the rural population over a given period. It
is calculated as ln(RPt/RP0)/n
where n is the length of the period and RP is the rural population.
It is expressed as a per cent.

Average
annual rate of change of the percentage urban

Average
exponential rate of change of the percentage urban over a given period. It
is calculated as ln(PUt/PU0)/n
where n is the length of the period and PU is the percentage urban. It
is expressed as a per cent.

Average
annual rate of change of the percentage rural

Average
exponential rate of change of the percentage rural over a given period. It is
calculated as ln(PRt/PR0)/n
where n is the length of the period and PR is the percentage rural. It
is expressed as a per cent.

Urban
agglomeration

Refers
to the de facto population contained within the contours of a contiguous
territory inhabited at urban density levels without regard to administrative
boundaries. It usually incorporates the population in a city or town plus
that in the suburban areas lying outside of but being adjacent to the city
boundaries.

Metropolitan
area

Includes both the contiguous territory inhabited at
urban levels of residential density and additional surrounding areas of lower
settlement density that are also under the direct influence of the city
(e.g., through frequent transport, road linkages, commuting facilities etc.).

City
proper

A
locality defined according to legal/political boundaries and an
administratively recognized urban status that is usually characterized by
some form of local government.

Capital
cities

The
designation of any specific city as a capital city is done solely on the
basis of the designation as reported by the country or area. The city
can be the seat of the government as determined by the country. Few countries
designate more than one city to be a capital city with a specific title
function (e.g., administrative and/or legislative capital).

Urban
agglomerations annual growth rate

See:
Average annual rate of change of urban agglomerations

Average
annual rate of change of urban agglomerations

Average
exponential rate of growth of the population of urban agglomerations over a
given period. It is calculated as ln(PUAt/PUA0)/n where n is
the length of the period and PUA is the population of urban agglomerations.
It is expressed as a per cent.

Percentage
of the urban population residing in urban agglomerations

Population
residing in urban agglomerations as a percentage of the total urban
population.

Percentage
of the total population residing in urban agglomerations

Population
residing in urban agglomerations as a percentage of the total population.
