Philippines Life expectancy at birth, male (years)

Data:	Life expectancy at birth, male (years)
Year:	1960 - 2013
Country:	Philippines
Source:	World Bank (the information in this section is direct quotation from World Bank development data)
Series Code:	SP.DYN.LE00.MA.IN
Topic:	Health: Mortality
Short Definition:	Life expectancy at birth indicates the average number of years a newborn infant would live.
Long Definition:	Life expectancy at birth indicates the number of years a newborn infant would live if prevailing patterns of mortality at the time of its birth were to stay the same throughout its life.
Unit of Measurement:	0
Periodicity:	Annual
Base Period:	0
Reference Period:	0
Aggregation method:	Weighted average
Limitations and exceptions:	Complete vital registration systems are not common in developing countries. Therefore estimates of life expectancy must be derived from sample surveys or by applying indirect estimation techniques to registration, census, or survey data. Survey data are subject to recall error, and surveys estimating infant/child deaths require large samples because households in which a birth has occurred during a given year cannot ordinarily be preselected for sampling. Indirect estimates rely on model life tables that may be inappropriate for the population concerned. Because life expectancy at birth is estimated using infant/child mortality data and model life tables for many developing countries, similar reliability issues arise for this indicator. Extrapolations based on outdated surveys may not be reliable for monitoring changes in health status or for comparative analytical work. Annual data series from the United Nations are interpolated based on five-year estimates and thus may not reflect actual events.

Statistical concept and methodology:	Life expectancy at birth used here is the average number of years a newborn is expected to live if mortality patterns at the time of its birth remain constant in the future. It reflects the overall mortality level of a population, and summarizes the mortality pattern that prevails across all age groups in a given year. It is calculated in a period life table which reflects a snapshot of a mortality pattern of a population at a given time. It therefore does not reflect actual mortality patterns that a person actually goes through during his/her life, which can be calculated in a cohort life table. High mortality in young age groups significantly lowers the life expectancy at birth. But if a person survives his/her childhood of high mortality, he/she may live much longer. For example, in a population with a life expectancy at birth of 50, there may be few people dying at age 50. The life expectancy at birth may be low due to the high childhood mortality so that once a person survives his/her childhood, he/she may live much longer than 50 years.
Development relevance:	Mortality rates for different age groups (infants, children, and adults) and overall mortality indicators (life expectancy at birth or survival to a given age) are important indicators of health status in a country. Because data on the incidence and prevalence of diseases are frequently unavailable, mortality rates are often used to identify vulnerable populations. And they are among the indicators most frequently used to compare socioeconomic development across countries.
