Observed variation between populations in fertility-timing distributions has been thought to contribute to infant mortality differentials. This hypothesis is based, in part, on the belief that the 20s through early 30s constitute "prime" childbearing ages that are low-risk relative to younger or older ages. However, when stratified by racial identification over the predominant first child-bearing ages, maternal age patterns of neonatal mortality vary between groups. Unlike non-Hispanic white infants, African-American infants with teen mothers experience a survival advantage relative to infants whose mothers are older. The black-white infant mortality differential is larger at older maternal ages than at younger ages. While African Americans and non-Hispanic whites differ on which maternal ages are associated with the lowest risk of neonatal mortality, within each population, first births are most frequent at its lowest-risk maternal ages.

On the heels of the World Water Day , celebrated on March 22, there is a new research paper that champions a relook at rainwater harvesting RWH as one option for secure water storage and security for the Caribbean. Even in those jurisdictions where there are statutory requirements to install storage for rainwater, such as in The Bahamas, Barbados, etc, the actual use has been low. At the same time, the duo write that water utilities have, over the years, seen RWH systems as competition, leaving them unwilling to get involved in their provision. The researchers suggest there is a basis for a change in attitude.
