2006 CPBI Design

Scope and Coverage

The unit of enumeration is the establishment. It is defined as an "economic unit under a single ownership or control, i.e. under a single legal entity, engaged in one or predominantly one kind of economic activity at a single fixed location".

The scope of the census was confined to the formal sector and it consists of the following:

  • Corporations and partnership
  • Cooperatives and foundations
  • Single proprietorships with employment of 10 and over
  • Single proprietorship with branches.

Specifically, the 2006 CPBI covers the following:

1. All establishments with Average Total Employment (ATE) 10 or more, and
2. All establishments with ATE less than 10, except those with Legal Organization (LO=1, single     proprietorship) and Economic Organization (EO=1, single establishment)

that are engaged in economic activities by sectors mentioned above.

Sampling Design

For the mining and quarrying sector, all establishments were taken on a 100 percent basis.

Classification Systems

An establishment is categorized by its economic organization, legal organization, employment size, industrial classification, and geographic location.

Economic Organization

Economic Organization relates to the organizational structure or role of the establishment in the organization. The following are the types of economic organization:

  • Single establishment is an one which has neither branch nor main office
  • Branch only is an establishment which has a separate main office located elsewhere.
  • Establishment and main office, both located in the same address and with branch/es elsewhere.
  • Main office only is the unit which controls, supervises and directs one or more establishments of an enterprise.

Examples are warehouse of plants or wholesale establishments, repair shops or garage or terminals of transport establishments.

The size of the establishment is determined by its average total employment (ATE). The following are the employment size classification used in the 2006 CPBI:



Average Total Employment





















2000 and over



Industrial Classification

The industrial classification of an economic unit is determined by the activity from which it derives its major income or revenue. The amended 1994 Philippine Standard Industrial Classification (PSIC) is utilized to classify units according to their economic activities.

The amended 1994 PSIC consists of an alpha character and 5 numeric digits. The alpha character, which represents the major division, is denoted by the characters A to Q. The first two numeric digits represent the division; the first three numeric digits, the group; the first four digits, the class; and the 5 digits, the sub-class.

Example: C - Mining and quarrying

10 - Metallic ore mining
109 - Metallic ore mining, n.e.c
1091 - Iron ore mining
10910 - Iron ore mining

Geographic Classification

The geographic or physical location of the establishments was classified in accordance with the Philippine Standard Geographic Code (PSGC) as of December 30, 2006. The PSGC contains the latest updates on the number of regions, provinces, cities, municipalities and barangays in the Philippines.

The geographic domains of the 2006 CPBI for establishments with average total employment (ATE) of 20 and over are the provinces, independent component cities, chartered cities and highly urbanized cities and municipalities. On the other hand, the geographic domains for establishments with ATE of less than 20 are the regions.

Hence, the samples of the 2006 CPBI with ATE 20 and over shall provide data for 17 administrative regions, 81 provinces, 39 cities and municipalities. For samples with ATE less than 20, the data that will be presented is limited only for regional levels.


The effective response rate is 71.6 percent for the mining and quarrying sector. For establishments with ATE of 20 and over workers, the effective response rate is 87.9 percent while that for establishments with ATE of less than 20 workers it is 64.5 percent.

Concepts and Definitions

Economic activity or business is the activity of the establishment as classified under the amended 1994 Philippine Standard Industrial Classification (PSIC). Generally, the main activity of the establishment is the establishment's principal source of income. If the establishment is engaged in several activities, its main activity is that which earns the biggest income or revenue.

Employment is the number of persons who worked in or for this establishment as of November 15, 2005. The concept of employment as of the payroll November 15 was adopted for the first time in the 2002 ASPBI (reference year 2001).

Average total employment is the sum of the number of persons who worked in or for this establishment for all months of the year divided by 12, regardless of the number of months the establishment is in operation.

Paid employees are all persons working in the establishment and receiving pay, as well as those working away from the establishment paid by and under the control of the establishment. Included are all employees on sick leave, paid vacation or holiday. Excluded are consultants, home workers, workers receiving pure commissions only, and workers on indefinite leave.

Salaries and wages are payments in cash or in kind to all employees, prior to deductions for employees contributions to SSS/GSIS, withholding tax, etc. Included are total basic pay, overtime pay, and other benefits.

Value of output represents the sum of the total value of products sold, receipts from contract work and industrial services done for others, receipts from goods sold in the same condition as purchased less cost of goods sold, fixed assets produced on own account, and change in inventories of finished products and work-in-progress (ending less beginning).

Cost of materials, fuels and electricity consumed and industrial services refers to expenses incurred in the production of goods and industrial services such as materials and supplies purchased, fuels purchased, electricity purchased and industrial services done by others and change in inventory of materials, supplies and fuels (beginning less ending).

Fixed assets are physical assets expected to have productive lives of more than one year and intended for use and/or being used by the establishment. Included are land, buildings, other structures and land improvements, transport equipment, machinery and equipment, furniture, fixtures, and other fixed assets.

Book value of fixed assets is the initial value or acquisition cost of fixed assets less the accumulated depreciation.

Value added represents the sum of census value added and value of non-industrial services done for others less the cost of non-industrial services done by others and other costs.
