Overview

• History of taking Population and Housing Census• Data Capturing prior to 2011• Data Capturing in 2012 census: Use of scanning technology• Experience in using CAPI• Making decisions on Using ICT tools in 2021 census

– Identification of method: CAPI, Web based etc.– Obtaining large number of hardware units– Use of units after the census– Timing of data collection– Structure of questionnaire

• Who take the decisions?• Ultimate Goal



• The first Census of Population and Housing was taken in

1871 in Sri Lanka

• Census has been conducted at 10 year intervals

• The last census which was the 14th in the series, was

conducted in 2012

• Until 2001 round de-facto method was used

• In 2012 round de-jure method was used

History of taking Population and Housing Censuses


• From 1871 to 2001

– Enumeration method: De-facto

– Data entry: Manual

– Editing: Manual

Data Capturing prior to 2011


• Census 2012 adopted image based form processing technology such as OMR/ICR through scanning the questionnaire

• e-Census technology was introduced for the first time on experimental basis

Data Capturing prior to 2012 round: Scanning


• DCS used the scanning technology to process the paper questionnaires

• Challenges in Scanning technology

– Had to outsource

– 24-hr working in two shifts

– Special scanner paper & printing

– Storing questionnaires under AC environment

– Incorrect data due to shifting of images

Data Capturing prior to 2012 round: Scanning


• First time in the history of census

• Experimental basis

• Only selected household participated

• Obtained a security certificate from Sri Lanka Computer

Emergency Readiness Team (CERT/CC)

– To ensure that it is secure to handle such information

• Encrypted communication and secure identification

Data Capturing prior to 2012 round: e-census


• Demographic and Health Survey – 2016

– Used CAPI technology

– Technical and Financial assistances by World Bank

• Sri Lanka Labour Force Survey - 2016

– Used CAPI

– Technical and financial Assistances: KOSTAT

• Agricultural Household Survey – 2017/18

– CAPI being used

– Technical and Financial assistances - ADB

Experience in using CAPI


Making decisions on Using ICT tools in 2021 census

Identification of method: CAPI, Web based etc

• Working committee

• Steering Committee

• ICT division of the DCS

• Recommendation from the government Apex body on ICT: ICTA

• Other stake holders



Obtaining large number of hardware units

• Source of funding

• What to do after census with these units

– Use for other censuses and surveys conducted by the NSO

– Strengthening the government data collection mechanism

• Maintenance

• Safety



Timing of data collection

• If cannot obtain all required number of hardware units (Tablet

computers)

– Limit the number by combining census blocks

– Serve a brief questionnaire (on information likely to be varied) to house

hold to record information with respect to the census moment

– Enter this information when the enumerator visit the household and

collect other information



Structure of questionnaire

• User friendliness

• Colorful display on the tab

• Can we increase number of modules and questions


Ultimate Goal

• Time taken between completion of field work and

release of final report should be minimized

• Still we have a few years. Can we do all our best to

make sure within a few hours/days after completion

of enumeration of the last household at least a few

key indicators of the census are released!!!!!!!!!!
