Squad age profiles: League 2, 15 Nov 2020
These graphics are intended to give a quick visual overview of the age of players that each club has fielded in league matches using a technique very similar to “population pyramid” graphs, although I’ll freely admit that they’ve come out with shades of the Rorschach test (or as someone observed on Twitter, the Habitat lighting range).
Hopefully they’re fairly self-explanatory, but here’s a quick summary anyway:
For each club I’ve added up all the league minutes played by every player this season and calculated the percentage accumulated by players of every age, rolling up “18 and under” and “35 and over” for neatness’ sake.
Each vertical “step” on a club’s chart is a year, with the major age milestones denoted by slightly thicker lines (as per the labels on the left). The width of the coloured graph at each step corresponds to the percentage of minutes accounted for by players of that age.
I haven’t labelled the percentage values as the graphs were already getting pretty busy and I figured that the general shape and proportions were sufficient to compare teams against each other. I may revisit this (and a few other tweaks) later in the season once I’ve done a bit more tinkering.
I’ve also calculated the average age of each club’s starting line-ups this season and used this to sort all the clubs in a division from oldest to youngest.
Hopefully that’s enough to give you the idea, so let’s dive in.
Tranmere and Port Vale have fielded the division’s oldest starting line-ups so far with an average age of 29. Cheltenham deserve a mention for giving almost exactly half of their minutes to players already in their 30s.
Scunthorpe are comfortably the youngest side this season with the average age of their starting XI over a year younger than anyone else’s. More than 95% of their minutes have been racked up by players aged 25 or under.
