Chicago is the only city examined (compared to countries or states) but the volume of data ranging from 1993 to 2013 offer a total amount for examination fairly comparable to a state or country. There are distinct characteristics originating from the fact that a city has different needs and priorities from a state/country and of course many resemblances to one (e.g. no need for defence/border safeguarding expenses).

Results can be summarized as follows:

  1. The dispersion of the public budget is made in a balanced way through 52 agents (payers) to a network of local companies and authorities and there are also major global players as well.
  2. The fact that the city is a transportation hub and resides to lake Michigan is pictured on the graph as major nodes both payers and payees are present and belong to transportation, water management and public utilities sector.
  3. The graph diameter is 1 as there are payer/payee only nodes and modularity is 0.79 indicating specialization structure of the payment network. The companies with major weighted-in degree are mainly corporates and institutions offering goods and services related to health, education, construction and transportation/aviation/public utilities services.


In the illustration above, we can see the evaluation of payers (red nodes). The size of nodes in the graph is relevant to the amount of payments they give or receive (weighted degree), while their color is relevant to the amount of the money spent (weighted out-degree, major red).
