Introduction

Legal base of Census

Tunisian NIS is the first administrative and technical responsble of Census.

Governemental authority fixed the date of reference (28 april 2004) and made a decret to create national and regional commissions in order to follow different census operations.

Introduction

The System of 2004 Census: three steps;

Pre Enumeration ( 6 months before census with supervisors ; duration :about 4 months and a half)

Enumeration ( data collection )

Post Enumeration including data exploitation and results diffusion.

Exhaustivity and Pre Enumeration step( oct 2003 – janv 2004 )

Supervisors divided Tunisian Territory in geographicAreas well limited on field ( 31734 districts ), eachdistrict contain about 70 household. This repartition helped to :

Prepare and facilitate enumerators work ( district document prepared by supervisors is considered as a guideline for enumerator )

Prepare means of control for enumeration step

Enumerators deal with recapitulation statistics:

Number of localities

Number of housing

Number of household

Present resident population by gender.

Absent resident population by gender

Visitors by gender

Exhaustivity and Enumeration Step ( Avril 2004 ) (CNTD)

Exhaustivity and Enumeration Step ( Avril 2004 ) (CNTD)

• Manual Data Control of district documents with data of reference documents ( documents of pre enumeration).

• Return on the field to verify omissions and complete housing and household missed

Exhaustivity and Post Enumeration Step ( Avril 2004 ) (CNTD)

• Supervision and verification of control operation after computing data of reference and districts documents we returned on field when it was necessary

• Besides of the comparaison with statistics of:

Previous census Labor force survey Administrative statistics ( education, housing,….)

Learned Lessons

Rare cases of omissions was in urbain places and

was corrected by control agents .

Another small differences existed between the two steps

was a result of pre - interview methodology : supervisor

made a rapid pre – interview by asking light questions

(Number of housing, Number of household in the housing)

without insisting on technical concepts fixed by NIS.
