Series Information
For the fourth time, the Bureau of Labor and Employment Statistics is conducting the BLES Integrated Survey (BITS). Initially conducted in 2003, it is a nationwide survey of non-agricultural establishments that collects key information on labor and employment.

Abstract
Initiated in 2003, the BITS is a modular survey that integrates the data requirements on employment, industrial relations, occupational injuries and diseases and labor cost that used to be collected by the BLES through independent surveys such as Survey on Specific Groups of Workers (SSGW), Employment, Hours and Earnings Survey (EHES), Industrial Relations at the Workplace Survey (IRWS), Occupational Injuries Survey (OIS) and Labor Cost Survey (LCS). Each round of the BITS covers different aspects of employment and establishment practices. The inquiry on occupational injuries and diseases is a regular feature while that on labor cost is undertaken on a less frequent basis.
The main objective of this survey is to generate an integrated data set on employment of specific groups of workers, occupational shortages and surpluses, safety and health practices, occupational injuries and diseases and labor cost of employees. 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.

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 2008 BLES Survey Sampling Frame (SSF2008) is an integrated list of establishments culled from the 2006 List of Establishments of the National Statistics Office; and updated 2006 BLES Sampling Frame based on the status of establishments reported in the 2006 BLES Integrated Survey and 2006 Occupational Wages Survey. Lists of Establishments from the Department of Trade and Industry (DTI) and Philippine Chamber of Commerce and Industries (PCCI) were also considered in preparing the 2008 frame.
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, 5 or 6-digit levels. Geographical location was not considered in the stratification to allow for detailed industry groupings.
Sample Size: The number of establishment covered was 6,460.
Note: Refer to Field Operations Manual, Chapter 2.5

Deviations from the Sample Design
Not all of the fielded questionnaires are accomplished. Due to the inadequacy of the frame used , there are reports of permanent closures, non-location, 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. Non-respondents are made up of refusals, strikes or temporary closures and those establishments whose questionnaires contain inconsistent item responses and have not replied to the verification queries by the time output table generation commences. Respondents are post-stratified as to geographic, industry and employment size classifications. Non-respondents are retained in their classifications.
Note: Refer to Survey Metadata
Note: Refer to Survey Metadata
Response Rate
For 2007/2008 BITS, the response rates in terms of eligible units are 78.3% (for employment/safety and health practices), 78.1% (for occupational injuries and diseases) and 76.0% (for labor cost).
Note: Refer to BLES Integrated Survey Metadata
Note: Refer to BLES Integrated Survey Metadata
Weighting
Estimates are obtained by simple expansion, i.e. by multiplying the sample values at the cell level (industry and employment size) by the corresponding blowing -up factor which is the ratio of the estimated population of establishments to the number of responding establishments. These estimates are then aggregated to the desired totals.
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 a specific safety and health practice. A population ratio is obtained by dividing total estimate of a variable with the total estimate of another variable, e.g. total labor cost by the number of employees to arrive at average labor cost per employee or total workdays lost of cases resulting to temporary incapacity by corresponding number of cases to de rive average days lost.
Non-response is taken into account in the weighing procedure.
Note: Refer to Field Operations Manual, Chapter 2.6

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 3.2
Note: Refer to Field Operations Manual, Chapter 3.2
Data Collection Notes
The survey is conducted in coordination with the Regional Offices (except the National Capital Region Regional Office) 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 August 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, 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.
