The collation of suicide statistics for the UK, England, Wales, Scotland, Northern Ireland and ROI is not routinely provided by any other organisation. There are significant challenges in collating the suicide statistics from across the UK and ROI. There are variations in the calculation methods of suicide rates between the national statistical agencies and differences in the data. This leads to challenges in the collation and analysis of suicide statistics and comparisons across countries. In order to understand and prevent suicide it is very important that suicide data is as accurate and comprehensive as possible. This document also includes some comment on these issues, statistics and the availability of data.
