Involve of the economic state of the country with the level of migration

To determine such a link between a country's economic situation and migration,
it is necessary to find an economic indicator that would characterize the entire country's
economy. It was hypothesized that such an indicator could be the probability of default
in the country.
The Gilles Duphrenot and Anne-Charlotte Paret's "Sovereign Default in
Developing Countries" was used to calculate the probability, namely their projections
of four major sources of vulnerability in the country [1]. This development defines
three levels of risk of default, it is safe to dangerous: green, yellow and red.
