This is an algorithm, provided by "www.populationmondiale.com", giving in real time an estimate of the number of inhabitants of our planet. Take into account that the accuracy of this number may be 3%, less or more.
You can display the main mountain ranges of the world. The length of each mountain range, its highest summit and altitude were found by comparison of the English, French and German versions of Wikipedia, when available. Missing data were completed through Microsoft Encarta Atlas, Encyclopaedia Britannica and Google Earth.
You can display the location of the main rivers of the world. The names, length and crossed countries of each river were found by comparison of the English, Spanish, French and German versions of Wikipedia, when available. Missing data were completed through Microsoft Encarta Atlas, Encyclopaedia Britannica and Google Earth.
Each map is entitled with the English and local short form country name. Each country's position is shown on the main map with its local long form name written in bold Latin script in the lower left corner.
Under each map appears, in bold script, the English long name. It is followed by the local language short name. Only the sovereign states of the world are listed.
The surface of each country is given in square kilometres as it appears in Wikipedia.
Population censuses are not taken regularly and population must be considered as an estimate for 2009. The main source for that is a comparison between the Central Intelligence Agency World Factbook and the data available in the French, Spanish, English and German entries for each country in Wikipedia.
The Gross Domestic Product (GDP) value is a limited indicator for the standard of living and the Human Development Index (HDI) takes into account GDP and literacy wich is itself strongly correlated to average life expectancy. Moreover it is particularly difficult to have an accurate calculation of the average life expectancy at birth. Thus, we are giving here only the average life expectancy of the inhabitants of each country by groups: more than 80, 75 to 80, 70 to 75 and so on. Our source is Wikipedia and the World Health Organization 2007 World Health Report.
Internationally unrecognized or unclear status entities are listed here separately with their de jure and de facto characteristics.
