Let us suppose it was 43% in 2015, 45% in 2016, and 43% again in 2017. This raises further questions. This would mean it increased by 2% in one year and decreased by 2% in the following year. A previous Irish Sports Monitor suggested participation rarely changes by more than 1% per year. Strange.
I will have to return to the documents and try to uncover something that I must be missing.
