Nine in ten births are delivered in health facilities.

The choice of delivery location significantly impacts maternal and child mortality rates. Opting for a health facility with skilled attendants substantially enhances the chances of survival for both the mother and the newborn.

In 2022, the vast majority of deliveries in the City of Las Piñas, comprising 90.3 percent, occurred in health facilities such as hospitals, birthing clinics, lying-ins, outpatient care centers, specialized care centers, and similar establishments. This figure represented a slight decrease from the 91.4 percent recorded in 2021, indicating a consistent trend towards facility-based deliveries. Only a small proportion, 9.6 percent, of total births took place at home, with a mere 0.1 percent delivered in other locations. (See Figure 7 and 8)

Most newborn babies weigh more than 2,500 grams.

The nutritional assessment of newborns is typically determined by their birth weight, with the World Health Organization (WHO) categorizing infants weighing less than 2,500 grams or 5.5 pounds at birth as having a low birth weight.

In the City of Las Piñas, the majority of newborns, totaling 6,080, or 83.7 percent, exceeded the threshold for low birth weight. Furthermore, 2,724 or 37.5 percent of most babies weighed between 2,500 and 2,999 grams. (See Figure 9)

The majority of babies born to mother aged 25-29 years old.

The age group of 25–29 exhibited the highest frequency of live births, accounting for 2,084 or 28.7 percent of the total number of registered live births in the City of Las Piñas. This indicates that the majority of registered births in 2022 were to mothers aged between 25 and 29 years old, followed by the age groups of 30-34 and 20-24. (See Figure 10)

Those between the ages of 17 and younger and 35 years old and over are considered to be at "high risk" of pregnancy. This is because childbearing in these age groups is more likely to have complications during pregnancy and labor that may result in higher morbidity and mortality for both mother and child.

In 2022, approximately 7.9 percent of newborns were born to mothers younger than 20 years old, while around 18.3 percent were born to mothers aged 35 years and older. (See Figure 11)

Technical Notes

Civil Registration is the recording in the appropriate civil registers, vital acts and events that affect the civil status of individuals.

Vital Statistics are derived from information obtained at the time when the occurrences of vital events and their characteristics are inscribed in a civil register.

Vital acts and events are the births, deaths, fetal deaths, marriages, and all such events that have something to do with an individual's entrance and departure from life together with the changes in civil status that may occur to a person during his lifetime. Recording of these events in the civil register is known as vital or civil registration and the resulting documents are called vital records.

• Live Birth - is the complete expulsion or extraction from its mother of a product of conception, irrespective of the duration of pregnancy, which, after such separation, breathes or shows any other evidence of life, such as beating of the heart, pulsation of umbilical cord, or definite movement of the voluntary muscles. Whether or not the umbilical cord has been cut or the placenta is attached; each product of such a birth is considered live born.

• Sex Ratio - refers to the number of males per one hundred females.

• Usual Residence - refers to the place where the person habitually or permanently resides.

• Crude Birth Rate - The ratio between the number of live births in a population during a given year and the total mid-year population for the same year, usually multiplied by 1,000.
