Figures for the spelling Séamas, Republic of Ireland.
The CSO only publishes names given to three or more babies in a year. “Less than 3” means zero, one or two babies, and these years appear as gaps on the graph.
Number of babies registered each year
From 2018, spellings with and without fadas are counted separately. Earlier figures group these spellings together, so the graph has a break at 2018.
