As I showed in a post some weeks back here, the average attendance on the opening day last season for the league of Ireland was 2,892. This increased to 3,558 this season. This was good news for the LOI but, as I mentioned, the challenge is retaining fans for the second home game.
The chart below shows the attendance at the first and second home match this season for each club. While I know there is many moving parts here (day the match is on, derbies, fixture quality, away fans willingness to travel etc.), we see a drop off for most clubs. This occurred last year and my guess is that it is a recurring effect - many casual fans are attracted to the opening day but, for the most part, do not return.
Bohs and Rovers both saw an increase in attendance - both sides had two wins under their belt before the second home match (and Bohs were playing Rovers). Finn Harps were the only other increase. Perhaps being back in the Premier division brings a certain novelty factor.
