females of childbearing age (15-44 years).
Abortion Ratio
- Number of abortions reported
during a period per 1,000 live births occurring during the
same period.
Birth or Live Birth -
The complete expulsion or
extraction from its mother of a product of human
conception, irrespective of the duration of pregnancy
which, after such expulsion or extraction, breathes or
shows any other evidence of life such as beating of the
heart, pulsation of the umbilical cord or definite
movement of voluntary muscles, whether or not the
umbilical cord has been cut or the placenta is attached.
Heartbeats are to be distinguished from transient cardiac
contractions; respirations are to be distinguished from
fleeting respiratory efforts or gasps.
Birth rate
- Number of live births during a calendar
year per 1,000 population.
Birthweight
- The weight of a neonate determined

or extraction from its mother of a product of human
conception, irrespective of the duration of pregnancy and
which is not an induced termination of pregnancy. The
death is indicated by the fact that, after such expulsion or
extraction, the fetus does not breathe or show any other
evidence of life, such as beating of the heart, pulsation of
the umbilical cord or definite movement of voluntary
muscles. Heartbeats are to be distinguished from
transient cardiac contractions; respirations are to be
distinguished from fleeting respiratory efforts or gasps.

more weeks of gestation per 1,000 live births + fetal
deaths.

births to women of all ages during a calendar year per
1,000

before the neonate becomes 28 days old (up to and
including 27 days, 23 hours, 59 minutes from the

deaths per 1,000 live births.
Perinatalmortality rate
- The sum of infant deaths
of less than 7 days and fetal deaths with a stated or
presumed period of gestation of 28 weeks or more per
1,000 live births + fetal deaths of 28 or more weeks of
gestation.
Postneonatal death

infant at least 28 days of age but less than one year of
age.
