Relative attractiveness. (a) A relative global attractiveness of top 10 cities measured as the estimated amount of touristic activity per capita of urban population, it is plotted in the decreasing order of total attractiveness, (b) the structure of photographic activity within a city and (c) the structure of photographic activity of city residents. Figure 3(a) shows the number of domestic and foreign photographs divided by the city population (i.e., attractiveness per capita for domestic and foreign tourists). Figure 3(b) shows the percentage of photographs within each city depending on the type of user, while Figure 3(c) shows the share of activity type of users that reside in the particular city. For example, as depicted in Figure 3(b), Rome receives the largest amount of foreign tourist activity and Washington DC the smallest. And as depicted in Figure 3(c) people living in Washington DC have the largest share of domestic tourists while Parisians have the smallest.
