Study Notes
Total Fertility Rate
- The number of children born per woman if all women lived through childbearing years.
- Measured by the average number of children per woman, also known as TFR.
- Global TFR in 2024: 2.3
- Philippine TFR in 2024: 2.7
Trends in Fertility
- Global fertility rate is expected to fall from 2.5 in 2024 to 2.2 in 2050 then to 1.9 in 2100.
- Global TFR declined from 2.7 (2017) to 1.9 (2022).
Crude Birth Rate
- Annual number of live births per 1,000 people.
- Calculated by dividing live births by person-years lived within that population
- 2022 global crude birth rate is 16.8 per 1,000 people.
- CBR in the Philippines in 2023 was 12.8.
Filipino Crude Birth Rate
- In 2023, the Philippines had 1,448,522 live births..
- The crude birth rate in the past ten years has dropped by 17.2 % from 1,748,857 in 2014
- Average of 3969 babies born every day, which is 165 per hour, and nearly three (3) babies born per minute.
- Luzon (57.5% of all births), Visayas (18.2%) and Mindanao (24.3%) were leading regions in live births..
- CALABARZON, NCR and Central Luzon were leading in birth occurrences.
Maternal Mortality
- Annual female deaths from pregnancy/childbirth or management issues (excluding accidents).
- Includes deaths during pregnancy, childbirth, or 42 days post-pregnancy.
- Global maternal mortality ratio decreased by 34% between 2000 and 2020 (from 339 to 223 deaths per 100,000 live births).
Philippine MMR 2000 - 2020
- 2000 MMR: 129
- 2005 MMR: 122
- 2010 MMR: 105
- 2015 MMR: 88
- 2020 MMR: 78
Neonatal Mortality Rate
- Number of neonates dying within 28 days of birth per 1,000 live births.
- 2021 Philippine rate: 12.3 per 1,000 live births
- 2024 Philippine rate: 14.2 per 1,000 live births
- 2022 global rate: 6,300 neonatal deaths per day (approx. 2.3 million).
Global/Philippine Population
- Global population in 2024: 8.2 billion
- Philippine population in 2024: 116 million
Mean Age at Childbearing
- Average age of mothers when giving birth in a given year.
- Philippine mean age in 2020: 28.9 years.
- This age steadily decreased from 30.7 (1975) to 28.81 (2020).
