Spatial aspects

Along with the previous

temporal aspects it is

necessary to study their

spatial aspects. Numerous

spatial models have been

used to represent the spatial

distribution of a given

population and its migrations

through a country’s network

of places.

Simultaneously, theoretical and practical studies, with data

observed in a large number of countries, permitted the

estimation of intricate parameters that are difficult to define

but easier to measure, that summarise correctly the internal

mobility flows irrespective of the parcelling of the studied

territory

This model has been re-examined recently by Martin Bell and Salut Muhidin in

2011 extended to a larger number of countries in the whole world, in a chapter:

Comparing internal migration between countries using Courgeau’s k (their index

k corresponds to the index kπδ of the previous formula). However these authors

say that this index has no plain language meaning. We showed with them that it

is possible to link such an index to the probability for a change of residence.
