Population geography
The population geography and population geography is a branch of human geography . In it one deals with the population of a spatial unit with the help of scientific survey and display methods . Of interest may include:
- Population density and distribution,
- Population structures (e.g. age composition, status characteristics, etc.),
- natural population development, d. H. Changes in the number of inhabitants ( births / deaths ),
- short- or long-term spatial and / or social mobility of the area population (see also migration research ),
- Forecasts of future population composition and number of inhabitants.
Questions relating to the definition of spatial units as well as a number of other statistical questions and definitions are connected with the questions shown here by way of example. The example of the number of inhabitants makes it clear: Here you can differentiate between a de jure number and a de facto figure . In countries with a regulated population registration system, the de jure population is often easy to ascertain: The number of residents who were registered with their permanent place of residence at a specific point in time in a specific spatial unit is used. However, the de facto population - i.e. the people actually currently present in an area - deviates from this statistical value to a greater or lesser extent (for example people who are not registered there for various reasons or who only have their job in the area and much more).
According to Jürgen Bähr , "(a) ls population [...] is the sum of the inhabitants of a precisely designated area at a precise point in time."
Applications
A large number of plans are based on figures that are as precise as possible for the total population or sub-populations of a room or a room unit. Since plans refer to future developments, for which no precise information can be given, conclusions about the future must be made from past and present knowledge using appropriate scientific methods. The methods of population geography are particularly in demand here.
