responses by question & section


Key Responses to Section on Institutional and Organizational Aspects (Part B)

• Almost all NSO’s have a special unit responsible for census mapping with staffing ranging from 10’s to 100’s.

• The main tasks of the census mapping unit/division) are the following:• Collecting data from various census and surveys to generate tables

at different administrative levels.• Develop a database of information (not limited to census and

surveys) that can be geographically referenced.• Prepare base maps and EA maps for censuses and surveys• Updating base maps and GIS information• Provide geographic information on enumeration areas for censuses

and surveys• Prepare and publish updated maps which include thematic and

statistical maps


Key Responses to Section on Institutional and Organizational Aspects (Part B)

• Close to all census mapping agencies collaborate regularly/occasionally with other departments & other NS offices or divisions within the NSO.

• Just over 50% of countries have statistical laws or laws governing the statistical production that explicitly deal with the production and/or dissemination of census data and/or maps.

• Many NSO’s have groups of national users of census maps and spatial data such as private and public institutions to help identify core issues and data needs of users

• More than half the country respondents have a National Spatial Data Infrastructure with several others proposed or in-the-works.


Key Responses to Section on Mapping Acitivites (Part C)

• Currently, most NSO’s are heavily engaged census mapping projects/activities

• Most are integrating (or plan to)new methods and technologies into census mapping activities

• More than half are currently producing base maps for census mapping activities

• Scales range largely from 1:1000 to 1:1,000,000 depending on the application (Country level, district level etc.)


Key Responses to Section on Mapping Issues (Part D)

• A summary of some the key issues for census mapping are:• Mapping of individual sites & specific areas (health/slums etc.) • Mapping of EA’s and related issues (digitizing/coding/splitting)• Preparing and maintaining a spatial database of digital information

and associated attribute attribute data• Using new technologies for census mapping operations• Preparing maps and databases for the operation of the census• Educating the NSO office of the importance of geographic data and

information• Acquiring better resolution imagery & increased GPS accuracy for

mapping operations• Improving training/recruiting staff in GIS & census mapping

Key Responses to Section on the Collection and Compilation of Census Mapping Data (Part F)

• Almost all country respondents have an initiative to improve the collection of census mapping data (maps, images, and vector/raster data) relevant for addressing census mapping issues through the use of GIS

• Many countries have special methods for the delineation of enumeration areas- several did not define a method

• Close to half of the country respondents have any initiative to improve the collection of data on topics of census mapping concerning mapping activities through Geocoding


Key Responses to Section on the Presentation and Dissemination of Census Geography Data (Part G)

• The majority of NSO’s regularly produce and disseminate census maps (thematic, statistical, topographic, etc.)

• The remaining plan to produce and disseminate census maps

• Several countries refer to documents published online for widespread use


Key Responses to Section on Training (Part H)

• Just over half the respondent NSO’s have had no training in census mapping with GIS either through workshops, formal/academic training, short and/or long term

• Several individually delegated respondents by country have had individual training

• Training of individual countries varies based on the level of GIS infrastructure use in census mapping activities


The expectations according to you…

• All participants are interested in gaining knowledge -be it increased or initial- on mapping and analysis of population dynamics using GIS.

• This includes:• Managing and Using data in a GIS • Using this data to produce useful tools such as maps and

analysis outputs• Better understand the usefulness of new technologies

which include free and open source software applications as well as commercial software and hardware.• Several expressed the need for increased understanding of the

role of GPS in census-taking• Several touched on the need to better understand geocoding,

EA delineation methods.

delimitation of census areas.Sri Lanka

Conducting field work to prepare maps at the census block level for the 2011 census

Thailand • Updating the base map to better guide future mapping activities



Brunei Darussalam• Organizing existing map stock to improve and benefit upcoming

census activities mapping Nepal• Preparing EA maps for municipalities throughout the country for

the 2011 P&H census. • Harnessing the use of digital orthophotos to aid development of

EA maps for census purposes.Phillipines• Utilizing existing data sources to improve GIS maps of specific

regions


Regional Summaries According to the Questionnaire

• According to the questionnaire responses, 78% of the countries use ESRI products (ArcInfo/ArcGIS or both)

• 44% use both ESRI Products and MapInfo (now called Pitney Bowes MapInfo)

• 11% use MapInfo only

33% of countries do not have a GIS but plan to

Special methods for the delineation of enumeration areas:

• Largely In-House with some outsourcing

• Delineation of Enumeration Area commonly conducted at the urban scale at the moment

• Scales for Enumeration Areas vary, with common ranges from 1:500 to 1:25,000 for urban and 1:10,000 to 1:50,000 (vary by case)





Bhutan• Rule framed in the mapping manual for the surveyors- each EA consists of

max. 40 households/structures urban and 25 rural

• GPS coordinates taken for 25 households- surveyor delineates EA following the topographical features (rivers, footpath, etc.)

• If no physical features for delineation exist, imaginary line used.

• The EA maps have a title; Block Name; EA #; structure #; numbering is serially for particular blocks only



Malaysia• EA’s are restricted to the preferred range of 80-120 living quarters

or 500-600 people and do not to cross any administrative/local authority areas

Pakistan• Delimitation of EAs are carried out with the collaboration of

Provincial Revenue, Local Government & Education Departments • Each enumerator is assigned an identifiable area comprising 150

to 200 houses




Philippines• Delineation is conducted based on the following criteria:

• The estimated number of households to be enumerated exceeds 500;

• Estimated number of days to complete the enumeration of the EA exceeds 25 days; or

• Terrain, physical arrangement of households (scattered or clustered), and the distance of one household to another are expected to hamper the timely completion of the enumeration.



Types of Thematic, Statistical, Topographic Maps produced and/or disseminated by NSO’s:

• Health • Education • Social • Econmic• Agricultural• Communication• Census indicators

• Geographical Classifications• Relative Development Index

report• Census Atlases• Topographic• Population density• Population Distribution • Migration Analysis Reports



• ~30% of the questionnaire respondents have had training in census mapping with GIS either through workshops, formal/academic training, short and/or long term.



Expectations according to the ESCAP Group:

• Hands on GIS training related to census mapping• Increased knowledge about GIS-based data analysis and dissemination• New insights into possibilities of automating EA delineation • Developing spatial databases for census mapping • Capacity building for staff on GIS and its applications for census mapping. • Better-understanding of the use of GIS for improving EA maps, data collection

and data dissemination activities• Gaining a better understanding of Geocoding using GPS • Recommendations on how to plan for the use of GIS/GPS and geospatial

technologies in census taking• Learn new techniques of using contemporary technologies for census/survey

statistical maps.• Gain further knowledge on the use of GIS
