BRIEF HISTORY OF POPULATION
CENSUS
• Population censuses have a relatively short
history
• The interest in population size has been present
as long as socially organized human
communities
• Population counts throughout history, usually
associated with the demand for taxes or the
need to estimate potential military strength.
• It is only in the past 200 years or so that periodic
censuses were taken and the results factually
recorded.
Cont`
• The first census in the 20th century was
conducted in 1918. Further censuses being
conducted in 1935, 1944, 1956, 1963, 1969,
1979, 1989 and 2000.
• The latest 4 censuses were organized along
with the housing census.
• Since Mongolia became a member of
COMECON in 1962, the censuses in 1969,
1979, and 1989 followed the common principles
of population census in COMECON countries.
Cont`
• The 2000 census was the first census that
was organized in transition economy. In
addition, 2000 census followed UN
principles and guidelines in organizing
population census.
• In 2000, the main legislative environment
for the census was a provision of the
Statistical Law to carry out Population
census every 10 years.
DATA PROCESSING
• We have developed our application which
was used for data entry in-house.
• Coding – manually. But computer assisted
coding was used for purpose of testing in
some part of questionnaire
• Editing – both manually and automatically
• Entry or typing – manually
The processing system
• National Statistical Office (NSO) was not in a position
to begin the basic design of the processing system in
later of 1997.
• However, with the assistance of UNFPA and UNSD,
from the first quarter of 1998 NSO was provided with
new equipment, components and software.
• It was thus able to establish the basis for
strengthening the technical capacity required for the
2000 census.
• The NSO purchased a range of equipment including
38 Compaq computers, two ACER server computers
and other equipment.
Cont`
• On the software side, the NSO decided to
process the census using IMPS (Integrated
Microcomputer Processing System)
• Four programmers of the NSO participated
training in Japan, Kazakhstan and at the
Bureau’s headquarters in Washington D.C.
• Apart from the use of IMPS, the NSO
developed other census applications, for
example, using the CLIPPER and VISUAL
BASIC languages.
Cont`
• Data entry was designed for LAN using a
Windows NT Server V4.0 as the control center.
• The center-server computer was a Pentium II, 366
Mhz, 128 MB, and 9 GB SCSI HDD and the
operators’ computers were Pentium 133-166 Mhz
CPU, 16MB RAM, 1.2-2.1 GB HDD.
• A new server was purchased from Dell and
installed at the beginning of September 2000,
thanks to the generous support of the Australian
Government
Coding and data entry
• Most of the coding was done manually and
were used CSPro 3.3
• But some variables for example,
classification of occupation and class. of
all industrial activity was coded with
assistance of computer.
• A special application to speed coding
named SEARCH was also developed.
Cont`
• Automatically coding was very time saving
and coding had finished within 44 days.
• For data entry, computer editing and
tabulation, modules of the IMPS package
were used
Cont`
• Apart from the use of IMPS, the NSO
developed other census applications, for
example, using the CLIPPER and VISUAL
BASIC languages.
• Thirty-six computers (workstations) were
available for data entry
• Two servers were operating and
connected to the network.
Editing
• Editing was completed in two stages.
• In the first stage records were edited
manually
• In the second they were automatically
edited by using the editing module of the
IMPS package, Concor
Issues raised
• Many issues were raised during the 2000
census. Attempts to tackle the problems
encountered have certainly resulted in a
more streamline data processing service
within the NSO.
• The question of geographic distribution of
processing also needs pursuing.
• Given the advances in automatic data
transmission that can be expected
Data processing 2010 census
• NSC is aiming to utilize modern technology for data
processing
• NSC is establishing GIS to utilize in enumeration and
intends to use for data analyzing and dissemination
• GPS will be used for taking household waypoint also
• Data processing will be done in local networking
environment
• NSC is planning to utilize CSPro for data entry
• OCR/ICR will be utilized for small percent data
capturing of the questionnaire
• And detailed plan for data processing is under
discussion
