The Occupational Wages Survey (OWS) 2004 is the fourth in the series since the survey was designed to focus on the wage rates of relatively skilled occupations in industries likely to be affected by the changing global and economic structure. The survey aims to generate statistics for wage and salary administration and for wage determination in collective bargaining negotiations.
From 1997 to the 2004 survey rounds, the OWS was a complete enumeration survey of non-agricultural establishments employing 50 persons or more. The 2002 OWS was limited to Metro Manila due to budget cuts.
A total of 58 industries were covered in the 2002 and 2004 rounds, 57 in 1999 round and 52 in 1997 OWS. The selected industries numbered 43 in 2002 and 2004 OWS and 41 in 1997 and 1999 rounds.
Note: Refer to Metadata and Primer in Technical Documents.
A. Objectives
To generate statistics for wage and salary administration and for wage determination in collective bargaining negotiations.
B. Uses of Data

wages.
C. Main Topics Covered

Sampling
Statistical unit: The statistical unit is the establishment. Each unit is classified to 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.
Survey universe/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.
Sampling design: The OWS is a complete enumeration of non-agricultural establishments employing 50 persons or more. The design does not consider the region as a domain to allow for more industry coverage.
Sample size: For 2004 OWS, number of establishments covered was 8,779 of which, 6,827 were eligible units.
Note: Refer to Field Operations Manual Chapter 1 Section 1.5.
While the OWS is a complete enumeration survey, not all of the fielded questionnaires are accomplished. Due to the inadequacy of the frame used, there are reports of permanent closures, nonlocation, 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 geographic, industry and employment size classifications. Non-respondents are retained in their classifications. Sample values of basic pay and allowances for the monitored occupations whose basis of payment is an hour or a day are converted into a standard monthly equivalent, assuming 313 working days and 8 hours per day. Daily rate x 26.08333; Hourly rate x 208.66667.
The response rate in terms of eligible units was 82.1%.
Estimates are obtained by simple expansion, i.e. by multiplying the sample values at the cell level (region, industry and employment size: 50-199 workers and 200 or more) by the corresponding blowing-up factor which is the ratio of the eligible (retrieved, refusal, for verification, temporarily closed, on strike, unaccounted/no response) population of establishments to the number of responding establishments. These estimates are then aggregated to the desired totals.
Dividing the estimated total basic pay (or total allowances) in each occupation by the corresponding estimate of time rate workers on full-time basis results to the average monthly basic pay or average monthly allowances as the case may be. The monthly average basic pay and monthly average allowances are then summed up to provide the average monthly wage rates by occupation.
The median monthly basic pay is computed from the estimated distribution of workers by monthly basic pay. On the other hand, the median monthly allowance is computed only for those workers reported with allowances.

The regional statisticians, economists or personnel designated by the Regional Director supervised the data collectors/enumerators in their respective regions. 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.
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 selfaddressed envelope is provided. The establishments may also submit the accomplished questionnaires through fax. Delivery of questionnaires starts in July of the reference 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 records of establishments.
To assist the respondents in classifying their job titles that may have different nomenclatures than the 1992 PSOC, an occupational sheet is inserted in the questionnaire of an establishment whose industry belongs to the 43 predetermined industries that will be monitored on occupational wage rates. This sheet contains a list of the occupations being monitored in each of the industry and their corresponding job descriptions in accordance with the 1992 PSOC.
The occupations may vary across establishments depending on their industry classification. Establishments that fall outside the 43 industries are not given occupational sheets. However, in the event that the industry of such establishment has been misclassified in the sampling frame and it should have been provided an occupational sheet, the field staff is instructed to give the respondent the relevant occupational sheet. The two (2) occupations considered as ben chmark (accounting and bookkeeping clerks; and unskilled laborers except janitors, messengers and freight handlers) and their corresponding job descriptions appear in the pertinent portion of the survey questionnaire. Wage rates of these occupations will be monitored in all 58 industries covered by the survey.
Note: Refer to Field Operations Manual Chapters 3 - 5.
Data processing
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.
Note: Refer to Field Operations Manual Chapter 1 Section 1.10.
Data appraisal
Estimates of the sampling errors are not computed.
The survey results are checked for consistency with the results of previous OWS data and the minimum wage rates corresponding to the reference period of the survey.
Average wage rates of unskilled workers by region is compared for proximity with the corresponding minimum wage rates during the survey reference period.
