Infant Mortality is measured as the number of children who die before their first birthday, per 1,000 live births.

Infant mortality may be caused by many circumstances, including birth defects, preterm birth, low birth weight, maternal pregnancy complications, sudden infant death syndrome, and injuries such as those due to suffocation.

There is also a strong correlation between race and infant mortality. African Americans have disproportionately high rates of infant mortality when compared with whites, and lower income individuals also have higher infant mortality rates.

Infant Mortality data are updated annually and are available for the following localities:
