Thanks to the resources made possible by SVG technology, it becomes possible for the reader to navigate as he wishes through all of the available maps. 9 maps present all possible data combinations (total population at the three dates, population change 1979-1989, 1979-2002 and of course 1989-2002). One can zoom in on a given section of the map, change the number of data ranges in the maps of relative values, access data region by region, etc. Sliding the mouse over the map brings up informative labels on each region.
The commentary for each variable is presented in relation to the series of corresponding maps.
