Summary
This dashboard provides data on selected birth defects in Texas—overall and stratified by year, maternal age, maternal race/ethnicity, infant/fetal sex, pregnancy outcome, and Texas county.
Data Source
Texas Birth Defects Registry (TBDR) via the Birth Defects Epidemiology and Surveillance Branch (BDESB)
Data Description
Birth defects data in Texas are collected by the Texas Birth Defects Registry (TBDR) via active surveillance. The data presented in these visualizations include selected birth defects among infants and fetuses delivered during the most recent 5 years of data available (10 years for county data; 20 years for trends by year data) to women who were residents of Texas at the time of delivery.
Measure Information
Prevalence (cases per 10,000 live births) is a rate that measures the number of birth defect cases divided by the number of live births in a population during a time period, multiplied by 10,000.
Prevalence (% of live births) is a rate that measures the number of infants and fetuses with one or more regular reportable birth defects divided by the number of live births in a population during a time period, multiplied by 100.
Confidence Intervals are 95% for prevalence; this means that the confidence interval contains the true prevalence rate 95% of the time.
Average Per Year is a count that measures the number of cases or infants/fetuses during a time period divided by the number of years in that time period (e.g., number of cases or infants/fetuses over a 5-year period divided by five).
Percentage (%) of Total Cases is the proportion of cases for a given birth defect that have a certain pregnancy outcome (live birth or non-live birth).
