Methods used to evaluate census data

Demographic analysis of census results

Census data was evaluated by using

● Analysis of internal consistency check

Comparison with other household surveys

(tabulation , age-sex distribution, age pyramid)

● Using previous censuses

(population growth, balancing equation,..)

Comparison with administrative record

2010 population and housing census

11

Methods used to evaluate census data

Post enumeration survey (PES)

● Sample Design : Stratified One-Stage Sampling

● Matching results ● Listing : evaluated coverage error

● Enumeration : evaluated content error

● To measure level of both coverage and content errors

(age, sex, marital status, completed education)

(sample unit was enumeration area : EA : 2,159 EA)

Census data was evaluated by using

Report of Population Projections for Thailand, 2010-2040 ; estimated base on the 2010 census results

There was a significant improvement in the reporting of the age-sex structure of the population used in related products

Main results of evaluate census data

Evaluation of age-sex structure:


13

Internal evaluation of marital status data showed high consistency in the distribution of the population by marital status (which represented by the population who were single, married, widowed and divorced).

External evaluation of marital Status data showed consistency of marital status data in the 2010 census with the data of 2009 Reproductive Health Survey.

Evaluation of marital status data :



14

Evaluation of employment data:


There was consistency between employment data in the 2010 census and the labor force survey according to the different characteristic of

Employed, Unemployed person

Work status

Industry sector

Solve the problem on international migration

• Developing a survey technique and outreach strategy for incorporating migrant population in Thailand’s National Census,2010.

: Pilot study under technical

assistance(2008) by World Bank and IOM

Planning for 2010 PHC

22

Improve Data Capture/ Processing &Dissemination System

• Increse the use of ICR• Develop more user-friendly system : Census Info, Data Warehouse

• Publish more analytical papers : collaborate research with academic institutions

• Establish network with academic institutions :create more in-depth analysis of PHC results

• Promote the use of PHC at national, provincial

and local levels


23

Quality Control

1) Intensive training: theoretical and practical ( 4 days)

2 ) Field supervisors monitor the data collection process- Re-interviews (2 households/EA)

- Field edit checks of the data for completenessand consistency

3 ) Scanning of the questionnaire using ICR

4 ) Centralized editing for data correction(Manual and Machine Editing) 5 ) Post Enumeration Survey (PES)


After the completion of the census data collection,

a post enumeration survey (PES) was carried

out by the National Statistical Office (except

Bangkok, Nonthaburi, Samut Prakan, and Samut

Sakhon).

A stratified one-stage sampling was adopted in each

area (systematic sampling) ; the selected samples

were 2,159 enumeration areas. The purposes of the

PES were to determine the completeness and the

accuracy and to evaluate the coverage error and the

content error of the census data.
