Shows the number for the Samaritans on google.co.uk, but nothing for me on google.com. Google.co.nz has a helpline, but google.ca doesn't.

I wonder who decides which countries to roll this sort of thing out to? Is it done by someone who just looks up certain countries helpline numbers first, or do they roll it out based on which countries are searching heavily on key terms?

Google have a ton of hard data on how people live - and die - and they could use it to really optimise how society helps people in times of vulnerability and need.
