Abstract
The Bureau of Labor and Employment Statistics conducted the BLES Integrated Survey (BITS) in 2004 for the second time. The BITS was initially conducted in 2003. It is a nationwide survey of non-agricultural establishments that collects key information on labor and employment.
The main objective of this survey is to generate an integrated data set on employment, labor relations and occupational safety in the workplace. These data are inputs to studies on industry trends and practices and serve as bases for the formulation of policies on employment, conditions of work and industrial relations. To some extent, the survey results will also be used to assess the progress of decent work in the country.
Note: Refer to Field Operations Manual, Chapter 2.1

Sampling
Sampling Procedure
Statistical Unit: The establishment is the statistical or enumeration unit. Each unit is classified in an industry that reflects its main economic activity---the activity that contributes the biggest or major portion of the gross income or revenues of the establishment.
Sampling Frame: The 2004 BLES Survey Sampling Frame (SSF2004) is a list frame of establishments that is a partial update of the 2003 BLES Sampling Frame based on the status of establishments reported in the 2003 BLES Integrated Survey (BITS) conducted nationwide. Reports on closures and retrenchments of establishments submitted to the Regional Offices of the Department of Labor and Employment in December 2003 and January 2004 were also considered in updating the 2004 frame.
The previous sampling frames were largely culled from the 2000 List of Establishments of the National Statistics Office that was also partially updated based on the establishment status in BLES conducted surveys in 2001. Similarly, previous sampling frames were partial updates of the 1996 List of Establishments of the NSO and also based on responses to the BLES surveys conducted since 1997.
Stratification Scheme: Establishments in the sampling frame were stratified by 3-digit industry (domain) and by employment size (stratum), i.e. 20-99, 100-199 and 200 and over. However, industries observed to be heterogeneous within their 3-digit classification were further broken down at the 4-digit level. Geographical location was not considered in the stratification to allow for detailed industry groupings.
Sample Size: For 2003/2004 BITS, the total sample size is 7,191.
Note: Refer to 2003/2004 BLES Integrated Survey Field Operations Manual, Chapter 2.5

Note: Refer to 2003/2004 BLES Integrated Survey Field Operations Manual, Chapter 2.5
Deviations from the Sample Design
Due to the inadequacy of the frame used, there are reports of permanent closures, duplicate listing and shifts in industry and employment outside the survey coverage. Establishments that fall in these categories are not eligible elements of the frame and their count is not considered in the estimation. In addition to non-response of establishments because of refusals, strikes or temporary closures, there are establishments whose questionnaires contain inconsistent item responses that are not included in the processing as these have not replied to the verification queries by the time output table generation commences. Such establishments are also considered as non-respondents. Respondents are post-stratified as to industry and employment size classifications. Non-respondents are retained in their classifications.
Response Rate
For 2003/2004 BITS, the response rate in terms of eligible sampling units is 72.0 percent.
Note: Refer to Survey Metadata
Note: Refer to Survey Metadata
Weighting
Estimates are obtained by simple expansion, i.e., by multiplying the sample values at the cell level (industry and employment size: 20-99, 100-199 and 200 or more) by the corresponding blowing-up factor which is the ratio of the eligible population of establishments to the corresponding number of responding establishments.
The estimates are aggregated to the desired levels to arrive at total estimates of the population, e.g. number of minimum wage earners or number of establishments with unions. A population ratio is obtained by dividing total estimate of a variable with the total estimate of another variable, e.g. total lost workdays of cases resulting to temporary incapacity by corresponding number of cases to derive average days lost.

Data Collection Mode
Other [oth], mixed method: self-accomplished, mailed and face-to-face
Supervision
The regional statisticians, economists or personnel designated by the Regional Director supervised the data collectors/enumerators in their respective region. In provinces/areas where there were relatively many establishments to be covered, area supervisors were hired to assist the regional staff in the supervision of data collection activities. The BLES handled the field operations in the National Capital Region.
Note: Refer to Field Operations Manual Chapter 3 Section 3.2.
Note: Refer to Field Operations Manual Chapter 3 Section 3.2.
Data Collection Notes
The survey is conducted in coordination with the Regional Offices of the Department of Labor and Employment. On a project basis, employees are hired to personally deliver and retrieve the questionnaires from the establishments. In some instances, questionnaires are mailed to establishments in less accessible or conflict prone areas, in which case a self-addressed envelope is provided. The establishments may also submit the accomplished questionnaires through fax. Delivery of questionnaires starts in July of each year and retrieval will commence after all questionnaires have been delivered or within 10 working days from delivery to an establishment or on a date agreed upon by the contact person and the enumerator. The basic data originate from the payroll, accident and other related records of establishments.

Data Processing
Data Editing
Data are manually and electronically processed. Upon collection of accomplished questionnaires, enumerators perform field editing before leaving the establishments to ensure completeness, consistency and reasonableness of entries in accordance with the field operations manual. The forms are again checked for data consistency and completeness by their field supervisors. The BLES personnel undertake the final review, coding of information on classifications used, data entry and validation and scrutiny of aggregated results for coherence. Questionnaires with incomplete or inconsistent entries are returned to the establishments for verification, personally or through mail.
Microsoft Access is used for data encoding and generation of validation prooflists. After checking accuracy of encoding based on the prooflists, a conversion program using SPSS is executed to generate output tables.
