I would say this statement is true.
In the past century, the world has recorded a rapid increase and decrease in population in different geographical areas. This has been influenced by different factors such as urbanization and family planning.
Urbanization creates better employment opportunities and wages. It also provides better social amenities such as schools and hospitals. These encourage people to move from rural areas to urban areas in search of a better living. The migration results in a decrease of population is the rural areas and a rapid increase in population in the urban cities.
Increased access to contraceptives has enabled women to limit family sizes. Women are able to plan for the number of children they intend to have. This has generally decreased the population growth in developed regions.
A road map shows you the routes you can take from point A to point B. A topographic map shows altitude by contour lines. So the main difference is directions vs altitude.
There are differences between the different parts of Europe, but not everybody within an area will fit the mold. On top of that there have been people moving around within Europe for as long as Europe has had people living there.
People often say that Mediterranean Europeans are more passionate than people from the north. This might be true in some cases but I think it is also upbringing. If living in Western Europe, kids are told to not show what they feel all the time, not trow tempers, not to shout when upset. In the south this behavior is more accepted and not seen as bad in the same rate.
There is no line that divides north and south, or even north from central and central from south.
Vienna as all Austria is considered central, like Switzerland and the southern parts of Germany, Czech Republic, Slovakia and Hungary, which are neighbours and have always had influence on Vienna as well as being influenced by it.
When we talk about Northern Europe it is more Norway, Sweden, Finland, maybe also Denmark and Northern Germany, as well as the Baltic republics.
West is Ireland, UK, Netherlands, maybe again a part of Germany and France.
