The interest in tourism has always been strong, for its important role in economic flows among nations. On this study
we analyze the arrivals of international tourism (edges) over 206 countries and territories (nodes) around the world, on
the year 2004. International tourist arrivals reached a record of 763 million in 2004. We characterize analytically the
topological and weighted properties of the resulting network.
International tourist arrivals are analyzed over <i>in</i> strength and <i>out</i> strength flows, resulting on a highly directed network,
with a very heterogeneity of weights and strengths. The inclusion of edge weights and directions on the analysis of network
architecture allows a more realistic insight on the structure of the networks. Centrality, assortativity and disparity are
measured for the topological and weighted structure. Assortativity measures the tendency of having a high weight edges
connecting two nodes with similar degrees. ITN is disassortative, opposite to social network. Disparity quantifies the how
similar are the flows on a node neighborhood, measuring the heterogeneity of weights for <i>in</i> flows and <i>out</i> flows of tourism.
These results provide an application of the recent methods of weighted and directed networks, showing that weights
are relevant and that in general the modeling of complex networks must go beyond topology. The network structure may
influence how tourism hubs, distribution of flows, and centralization can be explored on countries strategic positioning and
