Labor Force Survey [hh/lfs]
Labor force statistics have been compiled by the National Statistical Office since 1963 when the survey was initiated. The year 1984-1997 three rounds of the survey for the whole kingdom had been conducted each year; the first round enumeration is held in February coinciding with the non-agricultural season, the second round is normally held in May in with new labor force come from students who just finish their schooling and the third round is held in August, during the agricultural season. Commencing from the year 1998, another round of the survey in November has been conducted.
Due to the increasing demand of data for formulating plans and policy at provincial level, the National Statistical Office has expanded sample size to propose statistical data at provincial level commencing from survey in February and August, 1994. For the fourth round in November 1998, data was presented at the first time and presentation data at provincial level.
After the economic crisis in the mid of 1997, the need of labor force data for planning and policy making were more in demand. In the year of 2001, the survey was conducted monthly. The survey data of three months were combined to present the quarterly. Data of February, May and August were presented in order to compare with the previous labor force survey and since September 2001, data were presented monthly. Beginning from the survey in January 2001, 5 items has been revised; age of persons in labor force was adopted from 13 years of age and over to 15 years of age and over in order to agree with the child labor law. The standard classification of occupation, industry and employment status were adopted, and area of local administration which the former sanitary which were included in non-municipal area were presently included in municipal area.
The main objective of this survey is to estimate the number and characteristics of the labor force in the country and in different regions periodically. The statistical data derived from this quarter of the survey include:
- the number of persons in and out of the working age (15 years and over) by sex
- the number of working age population by labor force status, age, sex, marital status, educational attainment
- the number of employed persons by interesting characteristics such as age, sex, educational attainment, occupation, industry, work status, hours work,
- the number of unemployed persons by interesting characteristics e.g. duration of searching for job, type of previous work.

Sampling
Sample design
A Stratified Two - Stage Sampling was adopted for the survey. Provinces were constituted strata. The primary and secondary sampling units were enumeration areas (EAs) for municipal areas and non - municipal areas and private households / persons in the collective households respectively.
Stratification
Provinces were constituted strata. There were altogether 76 strata. Each stratum was divided into two parts according to the type of local administration, namely municipal areas and non - municipal areas.
Selection of primary sampling unit
The sample selection of blocks / villages were performed separately and independently in each part by using probability proportional to size - total number of households. The total sample blocks / villages was 5,796 from 109,966 blocks / villages.
The total number of sample blocks / villages selected for enumeration by region and type of local administration was as follows :
Region / Stratum
Bangkok Metropolis, total number of sample enumeration areas -> 312, number of sample enumeration in municipal area -> 312
Central (excluding Bankok Metropolis), total number of sample enumeration areas -> 1968, number of sample enumeration in municipal area -> 1080, number of sample enumeration in non-municipal area -> 888
North, total number of sample enumeration areas -> 1236, number of sample enumeration in municipal area -> 696, number of sample enumeration in non-municipal area -> 540
Northeast, total number of sample enumeration areas -> 1296, number of sample enumeration in municipal area -> 720, number of sample enumeration in non-municipal area -> 576
South, total number of sample enumeration areas -> 984, number of sample enumeration in municipal area -> 528, number of sample enumeration in non-municipal area -> 456
Selection of secondary sampling unit
Private households were our ultimate sampling units. A new listing of private households were made for every sample block / village to serve as the sampling frame. In each sample block / village, a systematic sample of private households were selected with the following sample size :
Municipal areas : 15 sample households per block
Non - municipal areas : 12 sample households per village
Before selecting sample private households in each sample block / village, the list of private households was rearranged by household ’ s size - member of the household and type of economic household.
All special households located within the sample areas were included in the sample and the persons in the special household were systematically selected for the interviewing.
The total number of sample private households selected for enumeration by region and type of local administration was as follows :
Region / Stratum
Bangkok Metropolis, total number of households -> 4680, households in municipal area -> 4680
Central (excluding Bankok Metropolis), total number of households -> 26856, households in municipal area -> 16200, households in non-municipal area -> 10656
North, total number of households -> 16920, households in municipal area -> 10440, households in non-municipal area -> 6480
Northeast, total number of households -> 17712, households in municipal area -> 10800, households in non-municipal area -> 6912
South, total number of households -> 13392, households in municipal area -> 7920, households in non-municipal area -> 5472
