Data processing & Analysis
• India has always been in the forefront of using the latest
technologies.
• Census 2001: India was one of the first countries to use the image
based Automatic Form Processing Technology taking the help of
High Speed Duplex Scanners for image capturing.
• Census 2011: India has adopted more developed ICR Technology
with advanced features.
• Uses the unique TILE module which optimizes data accuracy with a
systemized display of characters grouped together to allow easy
identification.
Data processing & Analysis…
• ORGI creates two seperate databases, the Houselisting & Housing
Census Data (at Household level) and the Population Enumeration Data
(at individual member of the Household level)
• Attempts made to link these two databases to cross-tabulate
information e.g cross tabs on Condition of Housing with Economic
Condition, etc.
• Boundary of the Enumeration Areas (EA) have been kept unchanged
during the two phases of the Census operation and provision has been
made in the Household Questionnaire (Phase 2 Operation) to record the
Household Number marked in the Phase 1 Operation
• Although the ORGI has made an effort to generate and release time
series tables from previous census there are challenging issues as many
jurisdictional changes occur, new villages and towns are created. Hence
an attempt is underway to link the databases available since 1991
Census on jurisdictional changes upto Town and Village levels in the
country.
Beyond Census 2011…

• Scanning of filled-in schedules completed
• Extensive quality check and data validation has been undertaken
at each stage of data processing and analyses, using the CS Pro
Software.
• Already published Tables on Houses, Household Amenities and
Assets.
• The task of data checking and validation has been made far
easier and quicker with the aid of technology

DATA DISSEMINATION
“A census is not complete until the data is disseminated and used,”
Dr. C. Chandramouli
Registrar General of India
• The Government of India relies heavily on the Census data in
formulating its Five-Year plans, Annual plans and various other welfare
schemes
• Biggest source of primary data on: Demography, Economic Activity,
Literacy & Education, Housing & Household Amenities, Urbanization,
Fertility and Mortality, Scheduled Castes and Scheduled Tribes,
Language, Religion & Migration

information pertaining to every resident : Houselisting Questionaire – 35
questions/Population enumeration – 29 questions.
• forms an important basis for formulating socio-economic and
administrative policies.
Data Dissemination Units: Hubs of
information
• Following 2001 Indian Census, the Office of the
Registrar General India framed a Data Dissemination
Strategy to be followed in all the 33 Directorates
• In 2002, a Data Dissemination unit (DDU) was set
up in all the Directorates
• DDUs have the latest facilities and technology, and
upgraded at regular intervals
Modes of Data Dissemination
• Printed reports (tables, State profiles, Analytical reports, Data Sheets on
important topics, Atlas, Booklets)
• CDs, DVDs including subject specific CDs
•
and downloadable files in the official Census website.
• Social networking site –
• Intranet facility at ORGI
• CensusInfo (Census India 2001 data disseminated using CensusInfo through an
interactive CD). The Provisional data of Census 2011 already on CensusInfo India
Dashboard
• Workshops/Seminars
• Digital Archive of Old Census Reports (1872 to 2011) in 33 DCOs in process
• A software module on

CONCLUSION
Censusinfo has been a boon for India. It is envisaged that CensusInfo will
aid in better and quicker dissemination of data, reaching a wider audience
Fact: Certain sections of society in any country do not have access to
technology
- As per Census India 2011, 15.54 Million households (6.3%
total population) in India have computers/laptops in their
with 7.6 Million households having internet connection
- 14.50 million broadband subscribers as per the Telephone
regulatory Authority of India (TRAI).

Challenge: Effectively disseminating data to those at the grassroot level
Action/Solution: A combination of the latest technology incorporated into
the traditional methods of dissemination of data will pave the way in
ensuring easy accessibility of data to reach a wider audience, including
the users at the grassroot level
