Abu Dhabi and SCAD
Abu Dhabi is the federal capital of the United Arab Emirates (UAE).
Last 40 years seen significant population growth and economic development.
Recognised need for official agency to provide statistics for decision making & policy.
In 2008, Statistics Centre – Abu Dhabi (SCAD) was established.
As a young statistical office, SCAD in fortunate position to review and implement best
practices from NSOs and other international statistical bodies.

To ensure that the time and effort from enumerators and SCAD census team, and the
good will of the citizens, were repaid with quality outputs.

Pre-requisites
1. Ease of use – tools do not require training or registration (intuitive).
2. Spatial representation – AD GIS integrated, expectation data presented in maps.
3. Take away data – first time data available electronically, easy to extract for analysis.
4. Sense of community – given growth, ability to know about local area important.
5. Confidentiality – privacy and protection of identification of individuals (Law #7).
6. Metadata – tools to link contextually to central metadata system.
7. Publishing standards – outputs consistent and meet SCAD standards.
8. Language accessibility – Arabic official language, most govt. services dual language.

User requirements
External users – utilised CRM analysis where reviewed all client requests related to
households, population and buildings.
Government users – SLAs with key agencies which provide guidance on the type
and format of data required. Additionally, meetings on functionality.
Internal users – expatriate professionals from international NSOs. Additionally, local
Emirati staff with previous census experiences – critical that design meets local ideals.
International review – various census on-line tools were studied. AD Census tools
incorporate some of the best practices from these tools.

Development
Timeframe - very compact compared with similar census tools (9 month devel). Proof
of concept using tools on other data sets (e.g. Foreign Trade Table Builder).
Development partner – SAS is SCAD’s selected vendor for data analysis/processing,
but also for dissemination. Census tools development was joint venture between
SCAD’s SIS Team and SAS.
Application architecture – multi-tier architecture. User interface developed with
J2EE based Java Server pages. The Census data resides in Oracle database as
back-end. SAS used as middleware - facilitates secure comms across front & back-
end layers.

Confidentiality
With the tools providing increased data manipulation, comes increased potential/risk
of disclosure.
A working group reviewed existing international disclosure control methods (both pre
& post-tabular).
Adopted a seeded random rounding to base 5. The seed, or ‘key’, ensures same
result is repeatedly produce and caters for differencing when subsets are generated.
Minimum output geography
Threshold of =>500 persons and =>5 households.

The Tools

The Tools
Census 2011 Thematic Maps
12
The Tools – Census 2011 Thematic Maps
The on-line thematic (choropleth) mapping tool allows user to quickly see census data
represented geographically.
Easily recognise spatial ‘clusters’ or ‘hot spots’.
While standard annotated maps show where something is in a place, thematic maps tell a
story about that place.
The tool includes standard mapping functions, such as: drag zoom, layer transparency,
pan, export, and colour palette.
Over 70 census variables, organised by theme, are available for selection.
13
The Tools
Census 2011 Community Tables
14
The Tools – Census 2011 Community Tables
Concept is to provide an instant statistical snapshot of a user-defined community.
Important aspect of the tool is to empower user to define their own ‘community of interest’
either from map or folder selection tools.
User can also select from 24 pre-defined census tables to form the basis of output report.
Report provided in PDF, Excel, or HTML formats.
15
The Tools
Census 2011 Table Builder
16
The Tools – Census 2011 Table Builder
Purpose to provide clients with the highest degree of freedom in selecting and combining
census data.
Users design their own census output tables by accessing variables and by modifying the
table structure to suit their own requirements.
Table builder also allows for easy export and offers some elementary data analysis.
17
Scenarios and Demonstration
1. AD Health Authority implementing new aged
health care services – like to know where older
persons are located?
18
Scenarios and Demonstration
2. Property developer interested in building a new
mall in Khalifa City - would like a social profile of
local area?
19
Scenarios and Demonstration
3. AD Education Council would like to know
highest level of educational attainment by gender
by regions in Abu Dhabi?

Conclusion
SCAD recognises its responsibility to expand and improve the quality, timeliness, and
accessibility of statistics produced in the Emirate of Abu Dhabi.
The suite of on-line census tools is evidence of SCAD’s commitment to this goal.
This project has set a positive benchmark for other future statistical outputs.
Thank You.
