All countries use CD-ROM/DVD and static web pages

GIS mapping tools also very common except Maldives and Nepal

Afghanistan: online databases

Bangladesh: print, CensusInfo under processing

India: dynamic web pages, GIS mapping tools

Maldives: MaldivInfo



Technological Tools

All countries use interactive tools for mapping, tabulating, analyzing and presenting data in graphs or other visual formats except Afghanistan, Nepal and Pakistan

Maldives uses SMS to reach users

Sri Lanka plan using dynamic web pages, online databases, GIS mapping tools and IHSN Toolkit



Websites for Interactive Tools

Bangladesh: BD Info: www.bbs.gov.bd (CensusInfo is under processing)

Bhutan: http://202.144.146.198/website/BhutanPHCB2005Dz/viewer.htm

India: http://www.censusindia.gov.in/2011-common/census_info.html

Geographic Information Systems

All except Maldives have GIS infrastructure to capture, manage, analyze and disseminate geo-referenced population and housing census data

Geographic Information Systems (contd.)

All census offices except Maldives have dedicated units for managing GIS

GIS is mostly used for cartography and dissemination of geo-referenced data.

Afghanistan, Bangladesh, Bhutan also used GIS in data collection

India census office also used GIS in data collection but does/will not disseminate “geo-referenced census data”

Afghanistan: large villages or cluster of smaller villages

Bangladesh: village

Bhutan: block

Pakistan: Mouza; block, Point Of Interest (POI)

Bangladesh: Census Law

Bhutan: Executive Order

India: Census Act 1948



Micro-data Confidetiality and AnnonymizationStatistical Law (contd.)

Maldives: Principles of Statistical Compilation: limits publication to aggregates; requires identity non-disclosure; and confidentiality for information that would disclose identity i.e. anonymity and confidentiality are required

Nepal: Statistical Law 1959: no disclosure of individual records (confidentiality required)

Pakistan: Statistical Act, 2011: ensures confidentiality; publication requires non-disclosure of individual identity or their state of affairs.

Sri Lanka: Ordinances: http://www.statistics.gov.lk/PopHouSat/CPH2011/index.php?fileName=CensusOrdinance



Micro-data Confidetiality and AnnonymizationProcedures implemented/planned for anonymization

Countries exclude micro-level identification names of individuals, households, village and enumeration

area codes serial numbers are given to individuals and households (e.g.

in Maldives)

Bangladesh: expect to implement/finalize with the National Strategy for the Development of Statistics

Bhutan: aggregate at higher geographical levels

Sri Lanka: does not release micro-data for public



Meta-data and Documentation

All countries provide meta-data

Mostly Data source (all countries) Variables and definitions (except Nepal) Structure and formatting of the dataset (except Bhutan and Nepal) Coding instructions and classifications (except Bhutan and Nepal) Sampling methodology and weighting (except Maldives and Nepal)



Meta-data and Documentation (contd.)

Not universally provided description on Census data processing procedures

(not provided by Nepal and Pakistan) Evaluation of census data quality

(not provided by Nepal and Pakistan) Confidentiality and anonymization procedures for the census data

(not provided by Afghanistan, Bhutan and Nepal)



Challenges in Dissemination

Common challenges are Expertise in new technologies e.g. dynamic web pages, mobile

technology and GIS (e.g. in Bhutan, Maldives, Nepal and Pakistan) Funding (e.g. in Bhutan, Nepal and Pakistan)

Other challenges areAfghanistan: politics (census is basis of resource allocation); security

problems limit publicity strategies; low literacy rate limits print medium outreach (uses religious leaders - educating them is also a challenge); lack of electricity and poor conditions in some areas limit radio/television outreach



Challenges in Dissemination (contd.)

Bangladesh: meeting stipulated/short time span for dissemination

India: Census Office: multiple-languages, reaching rural and remote areas, less internet penetration

Maldives: presenting and addressing specific issues for decision making at policy level; improving use of data by policy makers
