Socio-economic models of divorces in different societies
  Population dynamic of getting divorced depends on many global factors, including social norms, economy, law or demographics as well as individual factors like the level of interpersonal or problem-solving skills of the spouses. We sought to find such a relationship incorporating only quantitative variables and test theoretical model considering phase transition between coupling (pairs) and free (single) preferential states as a function of social and economic. The analyzed data has been collected by UN across almost all the countries since 1948. Our first approach is followed by Bouchaud's model of social network of opinions, which works well with dynamics of fertility rates in postwar Europe. Unfortunately, we postulate that this pure sociological and pure economic approach fail in general. Thus, we did some observation about why it went wrong and where economy (e. g. Poland) or law (e. g. Portugal) has bigger impact on getting divorce than social pressure.
