Gestational Age Analysis
• The data on birth and gestational age are collected through the Vital Records Data Base.
• These data are collected under the Code of Virginia regulations governing reporting of vital events, which are compiled, aggregated and reported on by VDH’s Division of Health Statistics.
• The gestational age is collected by the physician or other delegated professional at the bedside during the birth process.

Length of Gestation
The length of gestation variable is collected by the Office of Vital Records from the Certificate of Live Birth. Length of Gestation and other birth variables are entered into the Vital Records data base and subsequently compiled and analyzed by the Division of Health Statistics.
