3. Civil registration systems Continuous, permanent, compulsory, universal recording of the occurrence and characteristics of vital events in accordance with the legal requirements in each country

5. Live birth • Death • Fœtaldeath • Marriage • Divorce Vital events in a civil registration system United Nations recommended events to be registered: • Annulment • Judicial separation • Adoption • Legitimation • Recognition

6. Civil registration system: Functions • Legal: vital records are the legal proof of the occurrence of the event • Administrative: vital records are used to assist other agencies to accomplish their respective purposes • Statistical: vital records are the best source of continuous statistics given the universal coverage of civil registration, and it is not subject to memory lapses and sampling errors

7. Vital statistics system • It collects information by civil registration or enumeration on the frequency of occurrence of specified and defined vital events as well as relevant characteristics of the events themselves and of the persons concerned • The production of vital statistics covers all the steps from the data collection up to their dissemination: collection, compilation, processing, analysis, evaluation, presentation and dissemination of data in statistical forms

8. Fertility and mortality statistics obtained from civil registration data • Registration forms Vital record Statistical report - Checked and transmitted to the institutions responsible for vital statistics - Component of the register - Needs to be preserved in a formal and permanent way In some countries and for certain events, the same form is used as: • Legal document • Medical certificate • Statistical report Thus, the same document is used as proof of the occurrence of the event, as the vital record and statistical report

9. Recommended items in the statistical report for the calculation of fertility statistics (cont.) • Characteristics of the child  • Sex • Birth weight • Characteristics of the parents • Date of birth of the mother/age • Marital status of the mother, • Date of actual marriage of the mother, • Educational attainment, • Gestational age,

10. Recommended items in the statistical report for the calculation of fertility statistics (cont.) • Characteristics of the parents (cont.): • Number of children born alive to mother during her entire lifetime, • Number of children born alive to mother during her entire lifetime and still living, • Fœtal deaths to mother during her entire lifetime, • Date of last previous live birth (or interval since last previous live birth) • Survival of last live birth • Usual residence of mother • Date of birth (age) of father

11. Recommended items in the statistical report for live births Birth record and/or birth statistical report • Characteristics of the event: • Date of occurrence and registration • Difference between the two -> delays • Place of occurrence • Tabulate for urban/rural or small admin. Subdivisions -> medical facilities • Place of registration • Follow back for clarification • Assess local registration work load • Obtain optimal geographic distribution of registration points

12. Recommended items in the statistical report for live births (cont.) Birth record and/or birth statistical report • Characteristics of the event (cont.): • Type of births (single, twin, …): • Record for both live-born infant and dead-born foetus • Attendant at birth • Physician, nurse, nurse-midwife, midwife, other paramedical personnel, lay person, or not stated.

13. Recommended items in the statistical report for deaths Death record and/or death statistical report • Characteristics of the event • Date and place of occurrence, • Date and place of registration, • Underlying cause of death, • Certifier • Characteristics of the deceased • Date of birth (age), • Usual place of residence (of mother if infant death), • Sex, • Marital status

14. Tabulation programme for fertility and mortality data • Tables providing required data for the study of levels and trends and geographic differences • Specifying data quality • Minimal list of tabulations: • Principles and recommendations for a vital statistics system, rev. 2 (UN – 2001) p.105

15. Calculation of fertility and mortality rates On the basis of registration data Step 1: Numerator from civil registration data Step 2: Denominator (population at risk) by using data from censuses or sample surveys or population registers • Need for adopting the same definitions in civil registration, censuses and surveys. E.g. definition of place of usual residence; geographic areas • Need for tabulating events by place of usual residence • Need for reconciling the time reference between civil registration and source used for the denominator

16. Use of civil registration for vital statistics – points to retain • Use of civil registration data, even if incomplete • Use several sources for vital statistics: • To evaluate the quality of statistics • To complement the information • Need for same definitions …, collaboration among agencies responsible for sources used • Use vital records/statistical reports that are informative and transmit them to the NSOs • Disseminate the data
