Abstract

The Labor Force Survey (LFS) is a nationwide survey of households conducted quarterly to gather data on the demographic and socio-economic characteristics of the population. It is primarily geared towards the estimation of the levels of employment and unemployment in the country. One of the objectives of the Labor Force Survey is to provide a quantitative framework for the preparation of plans and formulation of policies affecting the labor market. Specifically, the survey is designed to provide statistics on levels and trends of employment, unemployment and underemployment of the country, as a whole, and for the 17 administrative regions.

A total national sample of 42,768 sample housholds (rounds with Batanes sample) or 42,576 sample households (rounds without Batanes sample) will be alloted per survey round deemed sufficient to provide more precise and reliable estimates at the national and regional levels only.

The survey involves the collection of data on demographic and socio-economic characteristics of the population in general. The reporting unit is the household which means that statistics emanating from this survey refers to the characteristics of the population residing in private households. Persons who belongs to the institutional population are not within the scope of the survey.

c. Persons who are present at the time of visit, whose usual place of residence is outside the sample household but have stayed with the sample household even for less than 30 days, provided that they have been away from their usual place of residence for 30 days or more;

d. Persons who are not present at the time of visit, but are expected to return within 30 days from date of departure to their usual place of residence, which is the sample household; and

e. The following family members who are away at the time of visit:

 1 . Overseas contract workers (OCWs);

 2. Other overseas Filipino workers who have been away for not more than five years from the date of departure, and are expected to be back within five years from the date of last departure;

 3. Employees in Philippine embassies, consulates and other missions; and

Sampling procedure

The 2013 Master Sample for household-based survey:

In order to be more effecient in the conduct of household based-surveys, the PSA designed a master sample consists of randomly assigned and selected set of geographic areas with non-overlapping and discernable boundaries known as the primary sampling units (PSUs). The primary sampling unit (PSU) can be (1) the whole barangay, or (2) a portion of a large barangay, or (3) combinations of small barangays.

Provinces and Highly Urbanized Ciities as Sampling Domain

To provide sub-national or provincial level statistics with precise estimates the 2013 MS has 117 major domains as follows: 81 provinces (including the newly created province Davao Occidental); 33 highly urbanized cities (HUC) (including 16 citiies in the National Capital Region; and 3 other areas (Pateros, Isabela City, and Cotabato City).

Primary Sampling Units

In the 2013 MS design each sampling diomain(i.e., province/HUC is divided into exhaustive and non-overlapping area segments known as Primary Sampling Units (PSUs) with about 100 to 400 households. Thus, a PSU can be a barangay/Enumeration Area (EA) or a portion of a large barangay or two or more adjacent small barangays/EAs. The PSUs are then ordered according to the following: (1) North-South/West-East Geographic location; (2)decreasing proporion of households with overseas workers; and (3) decreasing wealth index.

Replicates

From the ordered list of PSUs, all possible systematic samples of 6 PSUs will be drawn to form a replicate for the most of the province domain i.e., 75 out of 81 provinces while all possible systemmatic sample of 8 PSUs will be drawn to form a replicate for most of the HUCs, i.e., 31 of 33 HUCs. Small province domains such as Guimaras, Siquijor, Camiguin, Apayao, and Dinagat Isalnds will have 3 PSUs per replicate. Batanes with very less PSUs formed will have 3 PSUs per replicate but will be covered twice a year only (i.e., January and July rounds only). For other HUCs, San Juan City and Lucena City will have 3 and 5 PSUs per replicate, while the other urban areas, Pateros, and City of Isabela will also have 3 PSUs per replicate while Cotabato City will be allocated with 5 PSUs per replicate.

For instance, in Cagayan with 1008 PSUs formed, a total 1008/6 = 168 possible systematic samples of size 6 or 168 R groups or replicates can be made. The 168 replicates formed are then sorted at random so that the first 4 replicates will be in the first round, next 4 in the second round, and so on.

Sample Allocation Scheme

For each domain, a total of 4 sample replicates will be allotted for each survey round. However, the total number of sample SSUs will be alloted proportionately to the measure of size of the PSU. Thus, a PSU with only 100 households would have less number of samples households than PSUs with 400 households but on the average there will be 12 sample households allotted for each PSU in HUCs and an average of 16 sample households alloted for every PSUs in province domains.

A total national sample of 42,768 sample households (rounds with Batanes sample) or 42,576 sample households (rounds without Batanes sample) will be allotted per survey round.

Mode of data collection

Face-to-face [f2f]

Research instrument

ISH FORM 2 (LFS questionnaire) is a four-page, forty three-column questionnaire that is being used in the quarterly rounds of the Labor Force Survey nationwide. This questionnaire gathers data on the demographic and economic characteristics of the population.

On the first page of the questionnaire, the particulars about the geographic location, design codes and household auxiliary information of the sample household that is being interviewed are to be recorded. Certifications by the enumerator and his supervisor regarding the manner by which the data are collected are likewise to be made on this page.

The inside pages of the questionnaire contain the items to be determined about each member of the sample household. Columns 2 to 10 are for the demographic characteristics; columns 2 to 5A are to be ascertained of all members of the household regardless of age. Columns 6 to 7 are asked for members 5 years old and over, while column 8 is asked for members 5 to 24 years old, column 9 to 10, for 15 years old and over, while columns 11 to 15 are asked for members 5 years old and over. Columns 18 to 42 on the other hand, are the series of items that will be asked of all the members 15 years old and over to determine their labor force and employment characteristics.

Other Relevant Information: The question on hunger experienced by any member of the family because they did not have food to eat, was asked to the head of the household. If in question A, the answer is Yes the frequency of experiencing hunger was asked in question B.

Most of the questions have pre-coded responses. The possible answers with their corresponding codes are printed at the bottom of the page for easy reference. Only the appropriate codes need to be entered in the cells.

Other items, however, require write-in entries such as column 14 (primary occupation) and column 16 (kind of business/industry), etc. For such items, it is required that the enumerator describes the primary occupation or kind of business/industry.

The ISH Form 2 is provided as Technical Documents.

Abstract

The Survey on Overseas Filipinos (SOF) was conducted as a rider to the October 2008 Labor Force Survey (LFS).

The survey was designed to gather national estimates on the number of overseas workers, their socio economic characteristics and other information pertaining to the overseas workers who worked or have worked abroad from April to September 2008. The remittances of the Overseas Filipino Workers (OFWs) in cash or in kind were also accounted for the specified reference period. The SOF data are useful inputs to government planners, migrant advocates, researchers, academes, concerned citizens, and other data users to the formulation of policies and programs for the welfare of the overseas Filipino.

Geographic coverage

The geographic coverage consists of the country's 17 administrative regions defined in Executive Order (EO) 36 and 131. The 17 regions are:

National Capital Region (NCR) Cordillera Administrative Region (CAR) Region I - Ilocos Region Region II - Cagayan Valley Region III - Central Luzon Region IV-A - CALABARZON Region IV-B - MIMAROPA Region V - Bicol Region Region VI - Western Visayas Region VII - Central Visayas Region VIII - Eastern Visayas Region IX - Zamboanga Peninsula Region X - Northern Mindanao Region XI - Davao Region Region XII - SOCCSKSARGEN Caraga Autonomous Region in Muslim Mindanao (ARMM)

Overseas Filipinos whose departure occured within the last five years and who are working or had worked abroad during the past six months (April to September) of the survey period.

For purposes of this survey, overseas workers are the following:

Filipino overseas contract workers (OCW) who are presently and temporarily out of the country to fulfill an overseas work contract for a specific length of time or who are presently at home on vacation but still has an existing contract to work abroad. They may be landbased or seabased.

Landbased workers ? these are overseas contract workers who are hired either by direct hiring of an employer abroad; or through the assistance of Philippine Overseas Employment Administration (POEA); or through a private and licensed recruitment agency. They may have returned to the Philippines for a vacation (annual or emergency leave), or have transferred to other employers, or were rehired by their former employer.

Seabased workers ? these are overseas contract workers who worked or are working in any kind of international fishing/passenger/cargo vessels. Included also are OCWs who worked or are working for a shipping company abroad.

Other Filipino workers abroad with a valid working visa or work permits. Included also are crew members of airplanes such as pilots, stewards, stewardesses, etc. example: Filipinos working in countries such as U.S., Taiwan, Saipan, etc. with a working visa.

Filipinos abroad who are holders of other types of non-immigrant visa such as tourist/visitor, student, medical and others but are presently employed and working full time.

Persons not considered as overseas workers are:

Filipinos whose place of employment is outside the Philippines but whose employer is the Philippine government. Examples are Filipinos who worked or are working in Philippine embassies, missions and consulates abroad.

Filipinos who are sent abroad by the Philippine government or by private institutes for training, scholarship or any other similar purpose, even if they are known to be working abroad. Note that students who are sent abroad by private individual who are working or had worked there are excluded in this category.

Filipinos working in other countries who are hired as consultants/advisers of International organization such as the United Nations International Monetary Fund, etc.

Immigrants to other countries even though they are working abroad.

Sampling procedure

The Survey on Overseas Filipinos, as a rider to the Labor Force Survey (LFS), used the sampling design of the 2003 Master Sample (MS) for Household Surveys starting July 2003. The design of the Master Sample is described below:

1. Domain The 2003 MS considers the country's 17 administrative regions as its sampling domain. A domain is referred to as a subdivision of the country in which estimates with adequate level of precision is generated. It must be noted that while there is demand for data at the provincial level (and to some extent municipal and barangay levels), these were not treated as domain because of its large number (more than 80) and the large resource requirement it would entail.

2. Sampling Frame As in most household surveys, the 2003 MS made use of an area sample design. For this purpose, the Enumeration Area Reference File (EARF) of the 2000 Census of Population and Housing (CPH) was utilized as sampling frame. The EARF contains the number of households by enumeration area (EA) in each barangay.

This frame was used to form the primary sampling units (PSUs). With consideration of the period for which the 2003 MS will be in use, the PSUs were formed/defined as a barangay or a combination of barangays with at least 500 households.

1. Sample Size The 2003 MS consists of a sample of 2,835 PSUs of which 330 were certainty PSUs and 2,505 were non-certainty PSUs. The entire MS was divided into four sub-samples or independent replicates, such as a quarter sample contains one fourth of the PSUs found in one replicate; a half sample contains one-half of the PSUs in two replicates. The SOF as a rider to the LFS utilizes the full sample.

2. Stratification The 2003 MS considers the 17 regions of the country as the primary strata. Within each region, further stratification was performed using geographic groupings such as provinces, highly urbanized cities (HUCs), and independent component cities (ICCs). Within each of these substrata formed within regions, the PSUs were further stratified, to the extent possible, using the proportion of strong houses (PSTRONG), indicator of engagement in agriculture of the area (AGRI), and a measure of per capita income as stratification factors (PERCAPITA).

PSTRONG is defined to be the percentage of occupied housing units that are classified as made of strong materials in terms of both the roof and outer walls, based on the data from the 2000 CPH. A roof is considered made of strong material if it is made of either galvanized iron, aluminum, concrete/clay tile, half galvanized-half concrete, or asbestos. The outer wall is considered made of strong material if it is made of concrete, brick, stone, wood, half concrete-half wood, galvanized iron, asbestos or glass.

AGRI was determined in the following way: initially, an indicator variable was computed at the barangay level. That variable has the value 1 if more than 50 percent of the households in the barangay were engaged in agriculture or fisheries and 0 otherwise, based on the 2000 CPH Barangay Schedule. To obtain a measure at the PSU level, a weighted average of the barangay indicator variable was computed for all the barangays within the PSU, weighted by the total number of households in the barangay. Thus, the value of AGRI at the PSU level lies between 0 and 1.

PERCAPITA is defined as the total income of the municipality divided by the total population in that municipality. Note that the PERCAPITA value of the PSUs is the same if the PSUs are in the same municipality. The data on municipal income refer to year 2000 and were taken from the Department of Finance. However, if the 2000 municipal income was not reported to the Bureau of Local Government Finance (BLGF), 2001 income was used. If no 2000 or 2001 municipal income was reported, the income classification from the BLGF for this municipality was obtained. Using the data on income, which are presented in income intervals, the average of the lower and the upper values of the income interval for the municipal class to which this municipality belongs were determined.

1. Sample Selection

The 2003 MS consists of a sample of 2,835 PSUs. The entire MS was divided into four sub-samples or independent replicates, such as a quarter sample contains one fourth of the total PSUs; a half sample contains one-half of the four subsamples or equivalent to all PSUs in two replicates.

The final number of sample PSUs for each domain was determined by first classifying PSUs as either self-representing (SR) or non-self-representing (NSR). In addition, to facilitate the selection of subsamples, the total number of NSR PSUs in each region was adjusted to make it a multiple of 4.

SR PSUs refers to a very large PSU in the region/domain with a selection probability of approximately 1 or higher and is outright included in the MS; it is properly treated as a stratum; also known as certainty PSU. NSR PSUs refers to a regular too small sized PSU in a region/domain; also known as non certainty PSU. The 2003 MS consists of 330 certainty PSUs and 2,505 non-certainty PSUs.

To have some control over the sub-sample size, the PSUs were selected with probability proportional to some estimated measure of size. The size measure refers to the total number of households from the 2000 CPH. Because of the wide variation in PSU sizes, PSUs with selection probabilities greater than 1 were identified and were included in the sample as certainty selections.

At the second stage, enumeration areas (EAs) were selected within sampled PSUs, and at the third stage, housing units were selected within sampled EAs. Generally, all households in sampled housing units were enumerated, except for few cases when the number of households in a housing unit exceeds three. In which case, a sample of three households in a sampled housing unit was selected at random with equal
