A Critical Appraisal of Census Costs
Mr Iqbal AlamUnited Nations Statistics Division
Introduction
Census-taking has a long history
Most costly and elaborate data collection activity that governments’ undertake
Involves numerous agencies of government, private sector and NGOs at various administrative levels
Only statistical activity where every household in country participates
Main Census Cost Components
Census mapping
House numbering and household listings
Publicity
Staff recruitment and enumeration
Data processing, coding and data capture
Weighing Census Costs
Cost-reducing strategies should not compromise quality of information being collected
With rising census costs, often on account of growing populations, countries have to carefully weigh costs and benefits of their approaches at every stage
Essential for good planning when formulating initial census budget
Streamlined Census Questionnaire
Minimum number of basic topicsWhether users’ needs can be met from other
sourcesTopics well tested, easily asked and readily
answered
Exclude topics which do not need to be analyzed at
Subgroup levelDisaggregated geographical level
Sampling in Data Collection
At time of enumeration • For reducing field, training and processing costs and
enhancing data quality• Lessens burden of response for households not
included in sample• Leads to improvements in quality of information
collected
Great care needed in deciding upon appropriate sampling designClear instructions for implementation and supervision
Sampling in Data Processing
At the time of processing•For getting tabulations as quickly as possible•For reducing data entry time, particularly of coding, data capture and editing•Improving data quality•Avoids many of operational difficulties of field sampling
Release of sample results should not lower priority for full and timely processing
Training of Field Staff
Recruitment, training and management of census supervisors and enumerators is• Most expensive part of census operation• Requires very careful planning and
consideration• Differing approaches to training will be
required with different cost implications
Data Processing
Information technology – continuing evolution in census processing methods
Use of new technology – maybe cost reducing strategy but requires knowledge of developments in computer technology
Selection of inappropriate equipment can lead to even a higher costs
Approaches to Reducing Costs
A well designed census questionnaire
Editing specifications that produce clean master data files - avoiding reprocessing
Fewer and less complicated census tables for general release – electronic availability of data in compiled and record format
Supplies and equipment maintenance capability available in country
Conclusion
A well-planned and well-designed census pre-requisite for cost-effectiveness
If census costs not contained future of censuses will be in doubt
Need to consider cost saving measures beyond census sampling
Need to mobilze all stakeholders to share census costs
Learning from experiences and building on good practices a recipe for success
