There have been few studies on the safety of UC compared with homebirth, below are three, "older" studies. The World Health Organization has info. on women birthing alone but this is globally, and may indeed slant the percentages.
Home delivery and neonatal mortality in North Carolina.
Burnett CA 3rd, Jones JA, Rooks J, Chen CH, Tyler CW Jr, Miller CA.
Neonatal mortality examined by place and circumstances of delivery in North Carolina during 1974 through 1976 with attention given to home
**Planned home deliveries by lay-midwives resulted in three neonatal deaths per 1,000 live births; **planned home deliveries without a lay-midwife, 30 neonatal deaths per 1,000 live births; **and unplanned home deliveries, 120 neonatal deaths per 1,000
***3 vs 30!
The women babies were delivered by lay-midwives were screened in county health departments and found to be medically at low risk of complication, despite having demographic characteristics associated with high-risk of neonatal mortality.
Conversely, the women delivered at home without known prenatal screening or a trained attendant had low-risk demographic characteristics but experienced a high rate of neonatal mortality. *Planning, prenatal screening, and attendant-training were important in differentiating the risk of neonatal mortality in this uncontrolled, observational study.

Neonatal mortality in Missouri home births, 1978-84.
Schramm WF, Barnes DE, Bakewell JM.
A study was conducted of 4,054 Missouri home births occurring from 1978 through 1984. Of the 3,645 births whose planning status was identified, 3,067 (84 percent) were planned to be at home. Neonatal mortality was elevated for both planned (17 observed deaths vs 8.59 expected deaths) and unplanned home births (45 observed vs 33.19 expected) compared with physician-attended hospital births. ***Nearly all of the mortality excess for planned home births occurred in
**association with lesser trained attendants (12 observed vs 4.42
expected), while for unplanned home births the excess was entirely among infants weighing 1500 grams or more (19 observed vs 3.50 expected).
For planned home births attended by physicians, certified nurse-midwives, or Missouri Midwife Association recognized midwives, there was little difference between observed and expected deaths (5 observed vs 3.92 expected). There also was little
difference in deaths for unplanned home births weighing less than 1500 grams (26 observed vs 29.69 expected) compared with hospital births. **The study provides evidence of the importance of having skilled attendants present at planned home births.

Perinatal and maternal mortality in a religious group avoiding obstetric care.
Kaunitz AM, Spence C, Danielson TS, Rochat RW, Grimes DA.
We investigated perinatal and maternal deaths occurring among women who were members of a religious group in Indiana; these women received no prenatal care and gave birth at home without trained attendants. Members of the religious group had a ***perinatal mortality rate three times higher and a ***maternal mortality rate about 100 times higher than the statewide rates. These findings suggest
that, even in the United States, women who avoid obstetric care have a greatly increased risk of perinatal and maternal death.
PIP: All reported perinatal and maternal deaths from 1975 to 1982 among Faith Assembly members living in the state of Indiana were verified. Fetal death and the neonatal mortality rate were defined per 1000 live births; perinatal mortality was the combination of fetal deaths and neonatal deaths per 1000 births plus fetal deaths; and maternal mortality was calculated per 100.000 live
344 live births were identified in Elkhart and Kosciusko
Counties among religious members during this period. 291 of these mothers (85%) did not have prenatal care, the prenatal care for the remaining 53 (15%) was unspecified.
The mothers tended to be aged 20-34, white, married, and have minimum of high school education. 21 perinatal deaths were established among this population sample with 12 fetal deaths and 9 neonatal deaths. 11 fetal and 6 neonatal deaths occurred to members residing in the above 2 counties. Trauma or asphyxia at birth (often as a result of umbilical cord problems) and respiratory problems
were responsible for most of the mortality.
6 maternal deaths occurred: 4 due to hemorrhage and 2 caused by infection. During this period there was a total of 61 maternal deaths in Indiana, and thus about 9% of maternal mortality
occurred among Faith Assembly members (100% vs. 36% deaths caused by hemorrhage and infection). 3 of the 6 church members who died were 35 or older, and 2% of the births occurred to women 35 or older in these countries.
The estimated perinatal mortality rate for this group was 45/1000 live births vs. 18/1000 for the whole state, almost 3 time higher. The fetal mortality rate was 32 vs. 9 for Indiana (significantly higher); and the neonatal mortality rate was 17 vs. 9, respectively.
***The maternal mortality rate was 872/100.000 live births for church members residing in the 2 counties vs. 9/100.000 for Indiana: an astounding ninety-twofold higher rate. The risk of perinatal and
maternal death is greatly augmented even in the US when women do not utilize obstetric care
Seems MW attended homebirths might be the safest overall!
