Birth Defects: Where to Find Data

The California Environmental Health Tracking Program (CEHTP) provides data and information for 12 birth defects.  Our data query tool allows you to create your own tables, charts, and maps using data on infants diagnosed with birth defects within the first year of life.  These measures were developed in a joint effort by CEHTP, the CDC Tracking Program and grantees, and the California Birth Defects Monitoring Program (CBDMP).


The California Birth Defects Monitoring Program

CBDMP has been an active ascertainment, population based registry since 1982 when the California State Legislature authorized CBDMP to collect data on birth defects, stillbirths, and miscarriages.  CBDMP currently monitors a subset, over 40% of annual births in California, which represents the state’s geographic, environmental and racial/ethnic diversity.  The CBDMP registry data are used for ongoing surveillance to monitor rates and trends of select birth defects.


CBDMP reports current rates and occurrence patterns concerning factors such as race, ethnicity, geographic region, type of defect, mother’s age, and single and multiple births.
