The map that we are using is in the form
of the drafting film format. The map is available
only in Bangkok, municipal area and some big
villages in sanitary district and non municipal
area. The map is update periodically. For sanitary
district and non municipal area, updating the
number of houses of each village can obtain
from the village survey taken every year. The
village boundary and house location are still
rely on the head of the village.
For this census in Bangkok and municipal area,
the temporary employers are hired to update
the map, the change of land mark, new houses
and buildings. For sanitary district and non
municipal area, provincial officers will update
the map and group the ED. There will be 350-450
houses in one enumeration district in both municipal
and non municipal area for this census.
This year NSO have received the budget to hire
temporary employer to produce sanitary district
map. Since all sanitary district in Thailand
will become municipal area by this year. The
project will be completed in the year of 2000,
too late to be use for this census.
The Royal Thai Survey Department under the
office of Supreme Commander of the Armed Force
has authority to create digital map, but only
few provinces are completed. NSO asked for copies,
now we have the copy of three provinces.
Department of Town and Country and the Department
Development Quality have develop their digital
map for their purposes, which we also ask for
copies. We try to match these maps in order
to develop our own map.
With the very limited budget, NSO put more
emphasis in solving the problem of the main
frame computer for the year of 2000, the Intelligent
Character Recognition (ICR) for the census and
update the provincial office microcomputers
which is more urgent.
Some
Improvement of the 2000 census
Questionnaire form
NSO plan to use only one form of the
questionnaire. The size of the questionnaire
form is equivalent to the size of A3 paper.
After fold in half the questionnaire will look
like A4 size, This questionnaire will contain
the main characteristics (short form) and the
more detail characteristics of population question
together with the housing characteristics (long
form). This questionnaire form is decided to
be captured by the Intelligent Character Recognition
(ICR).
Data capture and data processing
The previous plan, NSO plan to decentralized
processing the census data. The completed questionnaire
forms will be manual edited, coded at the provinces
after that the coded questionnaire forms will
be sent to the center to be data captured. There
will be about 15 Intelligent Character Recognition
(ICR) station in all regions. After many tests,
the smaller size ICR can not handle the large
amount of questionnaire form. With the very
limited budget, It is more benefit to have only
one set of a very advance system with a very
good software station in Bangkok. The final
plan is, the questionnaire forms are still manual
edited and coded at the provinces. The coded
questionnaires will send to Bangkok to be data
captured by the ICR, and process the result
by using the main frame computer.
Methodology
The sample census enumeration technique similar
to that which was used for the 1970, 1980 and
1990 censuses will be adapted. For the last
three censuses in Bangkok Metropolis, sanitary
district non-municipal areas all persons and
household were listed and simultaneously enumerated
with the long form questionnaire. By the year
of 2000 all sanitary district will become municipal
area, then for this census the 20 percent sample
will be applied to all area.
