Notes:
 
Infant deaths: Deaths occurring to individuals less than 1 year of age.
Infant mortality rate: Number of resident infant deaths divided by total resident live births x 1,000.
Neontal mortality rate: Number of infant deaths that occurred within the first 27 days of life per 1,000 live births.
Postneontal mortality rate: Number of resident deaths occuring to individuals at 28-364 days of age divided by total resident live births x 1,000.
Low Birthweight mortality rate: Number of infant deaths with birthweight less than 2500 grams divided by total resident live births x 1,000.
---Triple dashes indicates that data is unavailable.
±Adding and subtracting the number shown after the ± symbol from the rate creates a confidence interval indicating that the true rate lies between the lower and upper bounds of this interval with 95 % statistical confidence.
*A rate is not calculated when there are fewer than 6 events, because the width of the confidence interval would negate any usefulness for comparative purposes.
- A dash indicates that there were either no births or no infant deaths from this category.
