HC correlates with brain volume, and it indicates an infant's intelligence. This study aims to discover the HC measure of infants aged 9-15 months related to their intelligence in the Sukabumi City and Cirebon Regency. The design of this study was a non-experimental quantitative design with a descriptive study approach and cross- sectional method.
