English: Graph showing of the progress of Livorno in the Italian football league structure since the first season of a united Serie A (1929/30). Only four upper tiers, hence the hole in the early 1990's. Note that the graph shows the position in the standings and not the place in the total league hierarchy, since Serie C (C1/C2) and Lega Pro have had up to four regional sections. The data is from the Italian Wikipedia.
