On the Tuesday the 1st of March and Thursday 3rd of March 2016 the Republic of Ireland Under-17 team played their Swiss counterparts in two friendly matches in the Waterford Regional Sports Centre. A team sheet was produced for the games which provide a list of players representing each country. Nineteen Irish players are list, alongside twenty Swiss. The list includes the date of birth of each player. I present this data below for both countries by month-of-birth and by quarter.
- Of the thirty-nine players selected for either country, just four were born after the 6th of August 1999.
- Just six of those selected were born in the second half of the calendar year. This means almost 85% of those on the squad lists were born between the 1st of January 1999 and 30th of June 1999.
- January alone accounts for ten of the thirty-nine players (25.6%).
- In total, twenty-one players (53.8%) are born in Q1 (January to March).
