1. Design and production of enumeration areas
• In 2010, SCAD undertook a frame update process (establishments,
buildings and persons).
• This frame, combined with new buildings data from municipalities,
formed basis for designing Census 2011 enumeration areas.
• Each enumerator assigned to a single work area (WA). Each WA could
be divided into max 4 sub-working areas (SWAs).
• Over 4,200 WA maps and 11,300 SWA maps created.
• Used ESRI ArcGIS for map design and quality control.

GIS – Defining the Census working areas
• Each enumerator assigned to a single work area (WA) and up to 4 subworking areas (SWAs).
• Over 3,500 WAs and 12,000 SWAs created.
•
Production of Census enumeration areas outsourced to GIS company
MapTel.
•
Quality assurance of every map conducted by SCAD over 4 week period.
•
Using ESRI ArcGIS.

2. Census collection using geo-enabled iPads & Galaxy Tabs
• The AD Census used around 3,000 iPads and Galaxy Tabs as primary
collection instrument.
• Each contained: interactive questionnaires (Arabic/English), GPS,
mapping system, and reference material.

• The mapping system displayed the allocated work area for each unique
enumerator and presented the buildings visited and those remaining
both in the iPad & Galaxy Tab and in Census back office.

• The mapping system also allowed tracking of each enumerator in the
Census back office.

3. Census dissemination - on-line thematic maps
• A recent UN review of population and housing censuses1 indicated
that “only 17 countries (16 per cent) use interactive online
databases” for census dissemination.
• SCAD is making a dedicated effort to provide innovative,
informative and free web-based tools to the public.
• As such SCAD, is developing three on-line statistical information
tools for accessing the rich source of census data.

Housing Censuses.

Dissemination: web service application
• Census release date - May 2012.
• On-line tools:
o Census Thematic maps
o Census Community Tables
o Census Table Builder
• The thematic mapping application will provide unique visual
analysis of the rich Census data.
• ‘Clusters’ or ‘hot spots’ are easily identified.

Dissemination: web service application
on-line thematic maps
Functions:
•
o Select from range of census variables.
o Select geographic level (e.g. sector).
o Select range types  Run
------------------------------------o All standard mapping functions: zoom, pan, transparency, export,
print, change mapping features (e.g. colours of ranges), etc.
o Dual language (English/Arabic)
Development:
o Data - SAS/Oracle
o Base map - ADSIC (GIS Cloud facility)
o Interface - ArcGIS API Flex (Flash)

GIS in Abu Dhabi Census 2011
Conclusion:
The various uses of GIS and other technologies in the recent
Abu Dhabi Census, demonstrates SCAD’s enthusiasm in
applying new technological initiatives for statistical collection,
processing, and dissemination.
SCAD recognises its responsibility in improving the quality,
timeliness, fitness for purpose and accessibility of statistics
produced in the Emirate, and is building tools and strategies
to meet these responsibilities.
