Thanks for the information that you brought to this discussion.

I am sorry to hear that some Americans " don't buy it" when confronted with the facts.
Sorry, but not the least bit suprised.

I am sure I came across a link on Wiki, supplied by someone else, that showed the USA , and the UK, and some other countries like Germany all use the same system to measure IMRs.
but no - the Americans still cite the ' fact ' that only they count prematures as live births, and that explains their failure to match the Brits and the Aussies.

if you can turn up this link as weel, i would be most grateful.

But good on you, cobbber, for coming up with this!
