English: The performance of Bologna in the Italian football league structure since the first season of a unified Serie A (1929/30). Only seasons in the top four tiers appear in the graph. Also note that the graph does not reflect any regional subdivisions within a tier. Thus the graph does not give an accurate picture of the team's position in the football pyramid as a whole, but only within its regional subdivision. This is relevant for: All seasons of the fourth tier, the vast majority of third tier seasons, and a few Serie B seasons.
