001 Land Area
Land area is total territorial area, excluding area under inland water bodies, national claims to continental shelf, and exclusive economic zones. 'Inland water bodies' usually means major rivers and lakes (United Nations Environment Programme, 2005). Exclusive economic zones are areas of sea from 22km to up to 392km from the shore of a coastal territory – for which the territory has jurisdiction over the exploration and exploitation of marine resources (the first 22km from the shore is the territorial sea).
Land area data will vary over time due to water management projects (damming rivers or draining submerged land) and changes in the level of the sea, lakes and rivers.
Most land area data used here comes from the United Nations Environment Programme (UNEP, 2005). UNEP sourced this data from the Food and Agriculture Organization's Production Yearbook and data files. Data for Hong Kong and Timor-Leste were included within the UNEP land area totals for China and Indonesia respectively – the land area of these smaller territories was subtracted from the land area of their larger neighbours. The data used is from 2002.
The World Bank's World Development Indicators (WDI, 2005) provided land area data for Luxembourg , Hong Kong , Timor-Leste and Monaco . The World Bank also sourced this data from the Food and Agriculture Organization's Production Yearbook and data files. And again the data used is for the situation as measured in the year 2002.
Figures for the land areas of Holy See (Vatican City State) and Taiwan are taken from Phillip's World Atlas and Gazetter, London : George Philip Limited (1994 edition). They are still applicable in 2002.
The population data (used to calculate population densities) is mostly sourced from Table 5 of the United Nations Development Programme's (UNDP) Human Development Report 2004. The medium variant projection for the population in 2002 was used. The population data for Saint Kitts & Nevis is calculated from Table 18 in the same report. The population data for the following territories, which are not included in the UNDP list of 177 territories, were taken from Table 33 of the Human Development Report 2004: Afghanistan , Andorra , Democratic Republic of Korea, Iraq , Kiribati , Liberia , Liechtenstein , Marshall Islands , Federated States of Micronesia , Monaco , Nauru , Palau , San Marino , Serbia & Montenegro , Somalia , and Tuvalu .
Population estimates for the Cook Islands (18,000 people), Holy See ( Vatican City State , 1000 people), and Niue (2000 people) were derived from the UNEP (2005) figures. The population data is estimates for the population living in 2002.
The population estimates for the Western Sahara (273,000), Taiwan (21,639,000), Greenland (56,000), and Puerto Rico (3,974,000) are from the Central Intelligence Agency's (CIA) “The World Factbook”. This data was sourced in January 2005; the most recent CIA data available in January 2006 was collected in July 2005. The estimated populations for these four territories in July 2005 were as follows: Western Sahara ( 273,008 people), Taiwan ( 22,894,384 people), Greenland ( 56,375 people), and Puerto Rico ( 3,916,632 people).

The source of the quote on the poster is Oxfam, 2006. “Oxfam is a development, relief, and campaigning organization that works with others to find lasting solutions to poverty and suffering around the world.” (Oxfam website, 2006). At the date of accessing the quote on the poster, January 2006, it was available at the following website:
Below is an explanation of each of the columns in the excel file:
Column A = The numerical territory code has been used to order territories in a consistent manner. The number is decided by the 2004 Human Development Index rank of the 177 territories included in the main United Nations Development Programme tables (1 being Norway with the highest Human Development Index in 2004). The other 23 territories are numbered in alphabetical order, starting at number 178.
Column B = Region and territory name. Regions consist of geographically contiguous territories and nearby territories. Region names are intended to be descriptions of the location of the region. The region names try to avoid describing regions as being far away places. In our naming of regions we also tried to avoid subsuming smaller territories in the name of a larger territory in the region, such as using 'Greater India ' for what we have termed ' Southern Asia '. In attempt to avoid confusion with other regional definitions we use 'Southern' rather than 'South' where we hope it is appropriate.
The territory names used are what appeared to be the most common spellings used by multiple United Nations agencies and on the Internet, using the Roman alphabet, in January 2006. Note, we have avoided using accents on characters because there is inconsistent use of accents for territory names by United Nations agencies. Examples of the various spellings and wordings for territory names are below; the name we use is first in bold, followed by examples of alternative spellings.
Albania, Republika e Shqiperise
Bahrain, Mamlakat al Bahrayn
Burundi, Republika y'u Burundi
Cape Verde, Cabo Verde, Republica de Cabo Verde,
Cote d'Ivoire , Côte d'Ivoire
Democratic People's Republic of Korea , Choson-minjujuui-inmin-konghwaguk
Kyrgyzstan , Kyrgyz Respublikasy
Timor Leste, Timor Lorosa'e, East Timor
Mexico , Estados Unidos Mexicanos
Morocco , Al Mamlakah al Maghribiyah
Mozambique , Republica de Mocambique
Sao Tome and Principe , São Tomé e Pr*ncipe, Sao Tomé et Pr*ncipe
Uruguay , Republica Oriental del Uruguay
Viet Nam , Vietnam , Cong Hoa Xa Hoi Chu Nghia Viet Nam
Yemen, Al Jumhuriyah al Yamaniyah, Al Yaman
Lastly, in some cases it was necessary to abbreviate country names in order that they would fit into certain sections of the poster. In order to maintain some consistency, the following abbreviations were made, when necessary, to reduce the length of the name.
a) If a well-used abbreviation already existed, it was adopted, this was done for the following:
' Former Yugoslav Republic of Macedonia ' was abbreviated to ' Macedonia FYR'
' Democratic People's Republic of Korea ' was abbreviated to 'DPR Korea '
b) 'Saint' was changed to 'St'
c) 'Democratic' was changed to 'Dem'
d) 'Federated' was changed to 'Fed'
Column C = Region codes, to identify which region each territory is in.
Column D = The ISO 3 code, or ISO ALPHA-3 code is a three letter code devised by the International Organization for Standardization. Codes are used as a short way of identifying a territory; their shortened form makes it easier to match data.
Column E = Land area of the world, each region and each territory. Measured in millions of hectares, thus the world's tot al land area is 13 056 billion hectares. A hectare is 100 metres by 100 metres.
Column F = People per hectare. This was calculated by dividing the number of people that live in a territory by the number of hectares in that territory. Regional population density is calculated by first tot alling the two sets of numbers (the populations and the land areas) from all territories within that region, and then dividing one by the other.
Column G = Population data comes from the sources detailed above. It is measured in millions. So the world population in 2002 was estimated to be 6242 billion.Source data and derived estimates.Technical notes are still being prepared for this data.
