HELP & INFORMATION

  
 

Official censuses and estimations are mostly the basis of the population figures presented on this web site; the definition of agglomerations is sometimes based on unofficial or own estimates. Please note that the data of such statistics are all of varying, and some of suspect accuracy. There are several reasons: the varying relevance and accuracy of the base data, the poor comparability of the definitions of agglomerations, errors in the projections and so on.

If population figures are depicted by an italic font, then they have a lower quality than the other data. Reasons may be (e.g.) that the value is based on my own estimates or calculations, that the referred area has changed its extension, or that the given population figure refers to another state or date of investigation than the other figures in the same column. For non-central cities and towns that belong to an agglomeration, the name of the central city of the agglomeration is often given as a relative link in agglomeration columns.

Links & References

Web links and references of the statistics presented here.

Valid HTML 4.01

Valid CSS

The presentation is tested by and optimized for Microsoft's Internet Explorer 7, Mozilla Firefox 3, and Google Chrome 1. The standards (transitional) HTML 4.01 or XHTML 1.0 as well as CSS 2.1 are observed. The pages are UTF-8 encoded if necessary. The installation of the fonts "Calibri" and "Tahoma" are recommended. JavaScript should be enabled.

The links of column headings allow a dynamic sorting of the table content.

Java

In addition to the statistics, which are presented on HTML pages, a map viewer shows the location and population of cities and administrative areas. For executing the map viewer, JavaScript and Java must be enabled. Java 1.1 is sufficient, i.e., Microsoft's VM as well as Sun's JRE works. Java 2 and Java 5 versions requiring Sun's Java plug-in offer extended functionality. The size of the map viewer is about 110kb (this number is not included in storage details given on the other pages; the first number is the size of the HTML page and the second value represents the map size).

In case of using a Java 5 VM, the visualization of satellite images is supported for newer maps (Menu "Mode"). This version of the map viewer is signed by a certificate, i.e. before using you must confirm following dialog:

Digital Signature

The satellite images are requested from the WMS Global Mosaic of Nasa; technical restriction may caused by this server. Instead, you can use other layers of the NASA server, of the GLOBE Program Visualization Server, or of the Demis Web Map Server.

diagrams

Using a Java 2 plug-in, the population figures can be visualized by an interactive diagram viewer.
