Readers are encouraged to c.onsult all fiveHandbooks, including the present Handbook and itsannexes and references.The present Handbook describes in its eightchapters the activities that countries should carryout to tailor their own civil registration system totheir specific historical, demographic, legal and administrative conditions at the time of computerization of such a complex system. Only in this waywill countries benefit from the investment made incomputerization.A phased approach is suggested for the computerization of civil" registration and vital statisticssystems. One suggested scenario for phased computerization would fie each phase to- specific vitaland civil status events. beginning with basic vitalevents and-if countries '0 wish and resourcespermit--culmmating in' a population registrationsystem. The importattce''Of initializing die computerized system with population Status data is a keyelement of the present Handbook. It is anticipatedthat the concepts presented in the text and the annexes will be helpful in easing the process of computerization of the civil registration system. TheHandbook should inspire' the responsible authorities to analyse the administration inplace and'Carryout the computerization. based OIL the actual statusof each specific country.The present Handbook looks at some of theeffects that computerization will have on civil regis.tration, including the possibility of developing aunique personal identification number as the key t.Othe system. The computerization of civil registration willcequire uniquely identifying each individual and ensuring that each and every vital event isrecorded once and only once, in both the civil registration and vital statistics systems. It recommends,for example. that countries follow a process thatleads to a unique numbering system to track the records of its vital events. However, a recommendation on the appointment of the unique petsonalidentification number as the national identificationnumber for each individual in the country is beyondthe scope of the present Handbook.Some of'the ex:amples used in the Handbookare taken from countries where population registersare closely linked with the civil registration system.In -some cases, the numbering system for civil registration is closely tied to the personal identificationnumber used to update information on individualsin the population register. As with cases in whichthe civil 'registration system is not tied to the population register, the examples provided are meant tobe illustrative ofthe computeri,zationprocess ratherthan to recommend a particular course of action.The Handbook concludes by considering some ofthe security measures needed by the two systems toensure confidentiality and the preservation of data.It also outlines the requirements of the hardwareand software needed to operate and maintain thesystems.It should be realized that a computerizedcivil registration system is not merely an electronicregistration of chronological series of vital eyentsand their retrieval. Indeed, computerization of thecivil registration system means much more. thanmerely doing electronically what is being donemanually by the present struCture.f or else it wouldnot be an important and usefutsubstitute for amanual civHregistration system. Accordingly. it would.be a great mistake to consider the computerization,of such complex systems as civil registration andvital statistics as a mere technical matter that can beachieved by any country.The target groups. of the present Handbookare made up' of countries with: (a) very differenttechnological practice. experience and skills; (b)very different legal and administrative practices;and (c) different financialmeandor accomplishinga computerization project. In addition, targetgroups range from countries with only manual registr!.lJionprocedures to countries that have initiatedcomputerization partly or to a',great extent. Becauseof that diversity of scenarios, at the. country, leve.!.the Handbook avoids step-by-step instructions for aparticular computerized civil· registration system;the usefulness of the Handbook would be very: limited if only one definite concept and one set of pro.,.cedures to be followed were given.The present Handbook was prepared by theUnited Nations Statistics Division, with the assistance of-eSC DataCentra!enof Denmark. a consultant for this purpose. A final review and revision ofthe Handbook from a technic.al anl'J editorial pointof view was conducted by Mr.l!)seph CameY3 Director of the Division of Health Slatisticsand VitalRecords. eoforado Oepartnl nt of PUblic Healthand Environment.

INTRODUCTION1.The present Handbook on Civil Registra·tion and VitalStatistics Systems: Computerizationis divided into eight chapters, as described below.goal. A project to computerize the civil registrationindexes in Scotland is used throughout the chapterto illustrate the phases.2. ChlJ:pter I outlines the key purposes andgoals of civil registration and vital statistics sys·terns. It looks at some Qfthe effects thatcomputeri·zatioJ). will ,have on civil registration, including thepossibility ofdeveloping a llnique:personal identifi·catioJlnllmberas the key to the system. The chapterthen examines the key are3.s of interface betweenthe -civil registration and- vital statistics systems.With reference to irnplernentiug the computerizedsystem, chapter lteconunends a phased approach.7.Computerizatlon·ofthe civil registrationsystem need not be limited to doing electronicallywhat is being done manually by the present struc·ture. Chapter VI considers the issues surroundingthe current strUcture of civil registration withincountries and what implications computerizationcan have on that structure. It gives specific recommendations concerning the type of strUcture to beused for both the advance planning and system de·velopment phases. as well as for basic organizationafter system implementation.3.Chapter n provides an overview of thedifferent stages O.f computerization. and discussesthe computerization of individual portions of thecivil registration ·system for countries that may notbe in aposition-toattempl full implementation. Thechapter concludes with more detailed informationconcerning the reconunendcd phased approach,Chaptermenumerates some of the major4.decisions and problem areas anticipated in-a moveto computerization. It specifically outlines ninemajor decision points that need to be anticipated,whether considering partial or complete computeri·zation.5; Chapter IV examines-the pmposeof computerizing the civil registration system. includingits effect on the vital statistics system and othergovernmental agencies. The chapter looks at theoption of using· a· personal identlfkation numberand considers the benefits to -be reaped from com·puterizationofciviI registration.6.Chapter V lists the phases to be includedin a computerization project. whether the countryhas a full.;.scale- project or a partial project as its8.The principal focus of chapter vn is thetransition from the civil registration system beforecomputerization to the civil registration system afterimplementation. It introduces the concept of "initialization" of the system, and outlines the proceduresnecessary to avoid a register that divides the popula·tion into those reported and those not reported.9.The Handbook concludes by looking athardware and software requirements in relation tothe functionality that the country -desires to obtainfrom the computerization of its civil registrationsystem. It considers isstres.surrounding the extrac·tion of data from the civil registration system foruse in the vital statistics system. Chapter vm alsooutlines some of the security measures needed bythe two systems.10. Crucial to the impact of the presentHandbook are its annexes; it is recommended thatthe reader consult each carefully. Of particular sig.nificance are annexes VIT, which contains an illustration of computerization in Seychelles, and vm,which describes the progress of computerization inScotland in recent years.1
