Definition

Live births that weigh less than 1,500 grams (3 pounds and 4 ounces)are reported on the mother's place of residence rather than the place of birth. Each year, there is a small number of births for which the newborn's weight is not recorded; these births with unknown weight are excluded from these calculations.

Data Source

Data petition to the Puerto Rico Department of Health, Auxiliary Secretariat for Planning and Development, Division of Statistical Analysis.

Notes

It is possible that the total number of births may not match the overall frequency. This discrepancy can occur for births where no municipality was specified or for those births that took place outside of Puerto Rico, even if the mother was a resident of a municipality in Puerto Rico.
