Query: The International Postal Network and Other Global Flows As Proxies for
  National Wellbeing   The digital exhaust left by flows of physical and digital commodities
provides a rich measure of the nature, strength and significance of
relationships between countries in the global network. With this work, we
examine how these traces and the network structure can reveal the socioeconomic
profile of different countries. We take into account multiple international
networks of physical and digital flows, including the previously unexplored
international postal network. By measuring the position of each country in the
Trade, Postal, Migration, International Flights, IP and Digital Communications
networks, we are able to build proxies for a number of crucial socioeconomic
indicators such as GDP per capita and the Human Development Index ranking along
with twelve other indicators used as benchmarks of national wellbeing by the
United Nations and other international organisations. In this context, we have
also proposed and evaluated a global connectivity degree measure applying
multiplex theory across the six networks that accounts for the strength of
relationships between countries. We conclude with a multiplex community
analysis of the global flow networks, showing how countries with shared
community membership over multiple networks have similar socioeconomic
profiles. Combining multiple flow data sources into global multiplex networks
can help understand the forces which drive economic activity on a global level.
Such an ability to infer proxy indicators in a context of incomplete
information is extremely timely in light of recent discussions on measurement
of indicators relevant to the Sustainable Development Goals.
