The data on infant and maternal mortality rates indicate several key points:

1. When comparing 15 technologically advanced countries, the United States does not have the lowest neonatal mortality rate. In fact, according to the CIA World Factbook, the US ranks 33rd in the world for lowest infant mortality rate, behind many European countries, Canada, Australia, and Japan.

2. The maternal mortality rate in the world's least developed countries is indeed significantly higher than in Europe. According to the World Health Organization, the maternal mortality rate in these countries can be up to 40 times higher than in Europe.

3. In sub-Saharan Africa, the infant mortality rate is alarmingly high. Approximately 3% of infants die before their first birthday. This is due to a variety of factors, including poor healthcare infrastructure, lack of access to clean water and sanitation, and high rates of infectious disease.

4. Also in sub-Saharan Africa, about 1 in 50 women dies due to complications of pregnancy and childbirth. This is a stark contrast to developed countries, where the maternal mortality rate is much lower. This high rate is due to factors such as lack of access to quality prenatal care, high rates of adolescent pregnancy, and high prevalence of HIV/AIDS.
