Introduction on Vital Statistics
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.
STRUCTURE OF VITAL STATISTICS SYSTEM
The production of vital statistics comprised of a system of operations in which the registration of vital events is an important component. The system begins with the registration followed by the processing and controlling of vital records and ends with the compilation and analysis of vital statistics.
Under Commonwealth Act (CA) 591, the Bureau of Census (now Philippine Statistics Authority) is mandated to generate general purpose statistics and to carry out and administer Act No. 3753.
Under the same law, the head of the PSA is also the Civil Registrar General (CRG) who directs and supervises the local civil registration activities in the country. The CRG in this regard is empowered to prepare and issue implementing rules and regulations on civil registration and to prepare and order printed the necessary forms for proper compliance.
The set-up of vital statistics system involves different entities and cuts across different departments and personalities.
For the registration of vital events, the Local Civil Registry Offices (LCROs), which are the registration units in the country and headed by the City/Municipal Civil Registrars (C/MCRs), are under the Local Government Units (LGUs). The hospitals, clinics, rural health units and similar institutions including barangay secretaries, practicing physicians, midwives, nurses, traditional midwives, solemnizing officers from various religious sects and denomination are required to assist in the reporting of vital events for registration at the LCROs. The concerned parents, next of kin, contracting parties, a witness or the person who has full knowledge of the occurrence of the event are also required to report the event, in default of the first mentioned set of informants.
The processing and controlling of vital documents are done at the LCROs and at the PSA Provincial and Central Offices.
The compilation and analysis of vital statistics is taken cared of by the PSA Central Office under the Vital Statistics Division of the Civil Registration and Central Support Office.
THE REGISTRATION METHOD
As mandated in Act 3753, all vital events that marked the entry and departure of a person in his lifetime and the changes in his/her civil status shall be registered. The registration method is defined as the continuous, permanents and compulsory recording of the occurrences and characteristics of vital events, primarily for their value as legal documents and secondary for their usefulness as a source of statistics.
Place where to register the event
As a general rule, the place of registration is the LCRO of the city of municipality where the vital events occur.
Out of town reporting of vital event occurs when the documents presented to the civil registrar of LCRO, which is not the place of occurrence, not for registration but to be forwarded to the civil registrar of LCRO where the event occurred and where it should be registered.
Forms to use
The civil register consists of certificates and the registry book. It also includes the actual copies of the registrable court decisions and the legal instruments concerning the civil status of persons. The certificates are loose-leaf forms in a set of four copies except for the Certificate of Foundling which is in a set of three.
Person who will report the event
The informant is the one who reports the event for registration and who gives information to be recorded in the civil register.
For death occurrences, the report shall be made by the hospital or clinic administrator if the person dies in the hospital or clinic, or by attending physician or by the nearest relative or by any interested party who has knowledge of the occurrence of death. In all cases, the report shall be submitted to the Local Health Officer (LHO) who shall direct and order the C/MCR to enter the death in the civil register.
Period when to report the event
Death or fetal death shall be reported to LHO within forty eight (48) hours from the time of death and the LHO shall direct or cause the registration to the C/MCR not later than thirty (30) days from date of death.
Any report made to the LCROs beyond the reglementary period are considered late and can be entered only in the civil register after the informant complies with the requirements for delayed registration.
Operative Act of Registration
The C/MCR sees to it that appropriate form it used; form is properly and completely filled-up; and proper attachments are submitted. In case, the entries are found incomplete, the C/MCR has to require the person concerned to fill up the document completely or to correct the entries.
When the document is accepted for registration, the date of receipt is recorded in the space provided and the documents received for the day are entered immediately in the appropriate civil registry book, assigning therein the corresponding registry number. After registration entry/entries found erroneous can only be corrected through RA 9048, except sex, nationality, age and status which require court approval.
Distribution of registered documents
Upon registration, the C/MCR distributes the copies accordingly: the first copy to the informant; the second copy to the CRG; the third copy shall be retained by the LCRO; and the fourth copy to the attendant or solemnizing officer, as the case may be. The CRG copy is the source of vital statistics published in this report.
