Census History n n n n 1948 1962 1969 1979 1989 1999 2009 (forth-coming) Kenya National Bureau Statistics http: //www. knbs. go. ke/ 2

Census Processing n 1948 – 1979 • ? ? ? Kenya National Bureau Statistics http: //www. knbs. go. ke/ 3

Census Processing (cont. ) 1989 • Manual data entry using IMPS software • Edits were carried out using Con. Cor module of IMPS • Tabulation was done using CENTS module of IMPS • Took 2 years to process Kenya National Bureau Statistics http: //www. knbs. go. ke/ 4

Census Processing (cont. ) 1999 n n n Receiving forms from the field Temporary storage Manual Editing Storage Preparation Scanning • Completion • Exception • Archiving • Data Cleaning • IMPS/CSPro Edits • IMPS/CSPro tabulation Kenya National Bureau Statistics http: //www. knbs. go. ke/ 5

Census Processing (cont. ) n Scanning • Used ICR/OCR • Procured 110 micro-computers, servers and printers • Two types of scanners were procured; Kodak models 3500 and 9500 • AFPSPRO software was provided by an Israel Company TIS Kenya National Bureau Statistics http: //www. knbs. go. ke/ 6

Challenges n n n The working space was insufficient resulting in overcrowding and hence poor supervision Lack of efficient tracking system for the movement of questionnaires from field up to tabulation Lack of fully licensed scanning software hampered questionnaire processing exercise Kenya National Bureau Statistics http: //www. knbs. go. ke/ 7

Challenges (cont. ) n n Delay in procurement of hardware and software posed a big challenge. The scanning technology was not pilotted Kenya National Bureau Statistics http: //www. knbs. go. ke/ 8

Lesson learnt n n Having adequate storage facilities to accommodate the voluminous number of questionnaires is vital as it facilitates easy retrieval and monitoring. The lack of storage space, racks and cabinets resulted in loss of substantial time when tracking down the whereabouts of questionnaires belonging to some areas. Given the complexity of the processes to be undertaken, it is of paramount importance that staff involved in the implementation of various processes be fully trained. Kenya National Bureau Statistics http: //www. knbs. go. ke/ 9

Lesson learnt (cont. ) n n The large number of steps and the overall speed of the processes mean that computer-assisted monitoring and control systems are required. Use of manual monitoring and control systems are inefficient. The requisite software to support hardware such as the one deployed in this census has to be in place before any data processing activity is embarked on. This requires careful technical evaluation of all aspects of hardware and software. Kenya National Bureau Statistics http: //www. knbs. go. ke/ 10

Way Forward n n To use ICR/OCR (OMR? ? ) scanning technology Adequately prepare for the technology by; • Studying available scanning technologies • Knowing the best practice by those who had used the technology and from experts • Training our personnel on the use of the scanning technology • Piloting on the use of the scanning technology • Acquire fully licensed scanning software Kenya National Bureau Statistics http: //www. knbs. go. ke/ 11
