I haven't found raw data but there seem to be two fairly recent key documents that support home birth. Perinatal mortality rates appear to be similar but is less risk of intervention to achieve this.

The largest prospective study of planned home births to date evaluates the safety of such births supported by direct entry midwives.
Among low-risk women, home births assisted by certified midwives achieve similar rates of intrapartum and neonatal mortality as hospital births, with lower rates of medical intervention, reveal Canadian researchers.
"Despite a wealth of evidence supporting planned home birth as a safe option for women with low risk pregnancies, the setting remains controversial in most high resource settings," note Kenneth Johnson (Public Health Agency of Canada) and Betty-Anne Daviss (International Federation of Gynecology and Obstetrics, Ottawa).
To examine its safety further, the team compared perinatal outcomes for all planned home births (n = 5418) supported by the North American Registry of Midwives in 2000, with those previously reported for low-risk hospital births in the USA.
Overall, 12.1 percent of women were transferred to hospital for delivery. The incidence of neonatal mortality among those who remained at home was similar to that documented for low-risk hospital births, with no maternal deaths. Medical intervention, however, was substantially less common among home, versus hospital, births, with epidural, episiotomy, forceps, vacuum extraction, and cesarean section rates of 4.7 percent, 2.1 percent, 1.9 percent, 0.6 percent, and 3.7 percent, respectively.
"Our study of certified professional midwives suggests that they achieve good outcomes among low-risk women without routine use of expensive hospital interventions," conclude Johnson and Daviss.
Here's an excerpt from the British Joint statement No. 2, April, 2007 on Home Births. I found it cited on the internet but haven't cross-checked it. I have no reason to believe it's untrue, however.
"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."
