The National Birthday Trust Study tried to look at all women planning a homebirth in the UK in 1994. 5971 women planning a HB at 37 weeks were included and their MWs tried to match them as closely as possible with women planning a hospital birth (the hospital control group eventually numbered some 4724 women). They found that the group which planned a homebirth were < 1/2 as likely to need assistance and < 1/2 as likely to need a CS. Babies born at home were likely to have better AGPAR scores at birth and need less suctioning and ressucitation. There were 5 stillbirths or neonatal deaths in each group - which was considered too small a number to allow a meaningful statistical analysis.
I know this study is old and the only summary I can find is on the homebirth site (which some of you will consider biased), but it does provide some real data to enable a comparison of the safety of home vs. hospital birth for women of similar (low) risk profile from a large enough population to be statistically meaningful.

2007 joint position statement from RCOG & RCM
("Summary: The Royal College of Midwives (RCM) and the Royal College of Obstetricians and Gynaecologists (RCOG) support home birth for women with uncomplicated pregnancies. There is no reason why home birth should not be offered to women at low risk of complications and it may confer considerable benefits for them and their families. There is ample evidence showing that labouring at home increases a woman's likelihood of a birth that is both satisfying and safe, with implications for her health and that of her baby.")
Similar study to National Birthday Trust, but 2003-2006 and in Canada
(can only get to the abstract anyway)
There was another study that came out in the BJOG in April 2008 looking at historical outcomes for homebirths (between 1994 and 2003), but there has been significant concern expressed over the source and analysis of many of the statistics concerning outcomes for women and babies that transferred from a planned homebirth here for a start.
From what I've read since I've been a member of this board and others (which is a few years now), one of the key issues is how you define when you "need" assistance or intervention. I don't want it determined that I "need" my labour to be augmented because I haven't dilated by at least 1cm an hour. I don't want it determined that I "need" an assisted delivery because I got to 10cm dilated an hour ago and the baby isn't out yet. Basically I don't want it determined that I "need" any intervention because I'm not fitting into a tick box sheet of hospital policy taken in isolation of any indicator that my labour and/or my baby are running into trouble. And when we asked questions of the MW who did the hospital tour that's pretty well what we were told would happen.
I assume that those policies are based on research that shows risks increase if those targets aren't met - but then I now know of other guidelines that have no research to back them up, or are based on research that is very badly flawed so I'm now less prepared to make that assumption than I was pre DD. None of this gives me confidence to put blind trust in the system, and based on my previous labour I need to be able to trust my HCP's becuase for the last few hours of DD's birth I wasn't in a place where I could have a rational discussion. I was (and still am) very concerned that too many maternity units are understaffed and so MWs are forced to fall back on policy and guidelines rather than being able to offer individualised, one-to-one care through sheer lack of time. It doesn't make me think that all hospitals are dangerous - but it also doesn't make me think that all hospitals are safe havens where the health and safety of me and my baby are going to be a MW's first priority for the duration of my labour.
woozlet - I completely agree that you never know that outcome of a course of action you didn't take. But that applies equally well to many of the "I/my baby would have died if I'd had a homebirth". Everyone I know personally who started out saying this to me decided, after talking about what actually happened, that this wasn't true for them as there had been indicators earlier in their labour that all was not well (even if the MWs didn't act on those indicators until it was an emergency situation, which makes me for them).
cory - I think you've found one of the biggest problems in trying to make an informed decision, and that's trying to get hold of the information... To me, the first two links are saying the same thing - the Netherlands has a suprisingly high neonatal mortality rate, but the high homebirth rate isn't to blame. The last one was too much of a human interest piece without enough hard data to draw any conclusions, really - they don't even seem to say what "recent study" has Sweden as the safest country to give birth in, and nor do they say how "safe" is defined.
