Introduction • Tunisian Census History • 1921: First Census • 1926, 1931, 1936 1946, 1956, 1966, 1975, 1984, 1994 • 2004: Last Census • 2014: Next Census
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.
Exhaustivityand Pre Enumeration step( oct 2003 – janv 2004 ) Supervisors divided Tunisian Territory in geographic Areas well limited on field ( 31734 districts ), each district 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
Exhaustivity and EnumerationStep( Avril 2004 ) (CNTD) Enumerators deal withrecapitulationstatistics: • Number of localities • Number of housing • Number of household • Presentresident population by gender. • Absent resident population by gender • Visitors by gender
Exhaustivity and Enumeration Step ( Avril 2004 ) (CNTD) • Manual Data Control of district documents with data of reference documents ( documents of preenumeration). • Return on the field to verify omissions and completehousing and householdmissed
Exhaustivity and Post Enumeration Step ( Avril 2004 ) (CNTD) • Supervision and verification of control operationaftercomputing data of reference and districts documents wereturned on fieldwhenitwasnecessary • Besides of the comparaison withstatistics of: • Previouscensus • 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.
