The GRDP includes regional estimates on the three major sectors including their sub-sectors namely:
1. Agriculture, Hunting, Forestry and Fishing (AHFF)
2. Industry Sector
- Mining and Quarrying
- Manufacturing
- Construction
- Electricity, Gas and Water Supply (EGWS)
3. Service Sector
- Transport, Storage and Communication (TSC)
- Trade and Repair of Motor Vehicles, Motorcycles, Personal and Household Goods
- Financial Intermediation (FI)
- Real Estate, Renting and Business Activity (RERBA)
- Public Administration and Defense; Compulsory Social Security (PAD)
- Other Services (OS)
In using the GRDP, the following points should be considered:
The following sectors (Manufacturing, TSC, RERBA, Trade and OS) are based on the Census of Philippine Business and Industry (CPBI) and Annual Survey of Philippine Business and Industry (ASPBI) results from PSA, which becomes available every two (2) years after the reference year. During the years when the CPBI or ASPBI results are not yet available, other indicators and the Quarterly Survey of Philippine Business and Industry (QSPBI) trend are used to produce regional GVA estimates. In the case of the TSC, subsequent adjustments are made based on the additional indicators from administrative data of LTO, PPA, PAL, ATO, and PPC.
The regional GVAs for each of the sub-sectors of agriculture, fishery and forestry are estimated indirectly using the gross value added ratio (GVAR) approach.
For private construction, regional distribution is based on the structure of the Building Permits data. For public construction disaggregation by region is based on the regional breakdown of the infrastructure program of NEDA and validated by the individual agencies' infrastructure programs.
For the sub-sector of electricity and water where available financial statements from NPC, MERALCO, REG, MWSS and LWUA can provide the required data inputs, the production approach is employed to estimate the regional GVAs.
The regional distribution of resources from the BSP factbook and Insurance Commission are used to estimate the regional GVAs of the Financial Intermediation sub-sectors.
For RERBA, regional benchmark estimates are obtained using the results of the latest Census of Population and Housing (CPH) and Family Income and Expenditure Survey (FIES). Regional data on the total floor area of residential construction available from Building Permits data of PSA serve as indicator for estimating the regional distribution of the number of occupied dwelling units.
The regional GVAs for the PAD are estimated based on the data from the Commission on Audit (COA). |
