How many attempted suicides are there in England and Wales

In the year 2007, the U.K. counted 5'377 registered suicides;3 in
England and
Wales this number counts to 4'301.4 Given the results of the scientific
research
mentioned before, the suicide attempts in England and Wales must be
estimated
to be up to 215'050 per year.

They've estimated the figure from a figure establised in the US that
approximately 50 times as many attempted suicides happen as completed
ones. I wonder where the data is collected for this?

In the UK people focus on the suicde rate rather than the attempted
suicide rate. It's one of the ways the gender prejudice about men's help
seeking behaviour is promoted by propaganda organisations. Men
successfully kill themselves more but women attempt suicide more. The
completed suicide rate is used to suggest that men don't seek help
however according to the attempted suicide rate and the figures from the
Samaritans (that show men contact them ever so slightly more
consistnetly for over a decade) it's women who have the problem with
help seeking.
