Data Note: Philippines - GDP SA - Source
Sunday, 01 Sep 2019 21:26 ET
By Annie Kao, Richard Grim
Summary
August 2019 -- For the quarterly national accounts of the Philippines, seasonally adjusted, we are now able to harvest major items directly from the source (four quarterly series revised). For consistency, we have altered the analytic form of our remaining SA supplements (50 quarterly series revised from 1981).
Detail

Previously, for these components (gross domestic product in agriculture, industry and services) we harvested the NSA series and calculated SAAR versions.

We have made these changes:

  1. For total GDP(O) and its A*3 aggregates, we are now able to obtain seasonally adjusted series directly from the source (four series). This manifests as a revision.
  2. We extended the series by 17 years.
  3. For the remaining SA supplements in the dataset, to be consistent with the source, we have changed their analytic form from seasonally adjusted at an annual rate (SAAR) to a quarterly rate (50 series). This manifests as a revision and change to unit-descriptor metadata.

Dataset properties:

  • Framework: PSNA (Philippines System of National Accounts), which generally follows UN SNA 2008
  • Measurement: Millions of constant year-2000 Philippine pesos (Mil. 2000 PHP)
  • Adjustment: Seasonally adjusted (SA)
  • Native frequency: Quarterly
  • Start dates: Reported from 1998Q1, extended to 1981Q1

The series reside in the historical catalog (Philippines » National Accounts » By value add | By Expenditure » Quarterly » Seasonally adjusted). Because catalog locations are subject to change, the upper-right search box on DataBuffet.com provides a "find in catalog" mode that accepts a mnemonic.

1. The four SA series that we now republish verbatim are:

  • NACSGDPAQ.IPHL   = National accounts: Production approach - Gross domestic product [GDP], (Mil. 2000 PHP, SA)
  • NACSGDPAFAQ.IPHL = GDP - Agriculture; hunting; forestry; fishing
  • NACSGDPIDAQ.IPHL = GDP - Industry sector
  • NACSGDPSVAQ.IPHL = GDP - Service sector

2. For the A*3 components (NACSGDPAFAQ.IPHL, NACSGDPIDAQ.IPHL, NACSGDPSVAQ.IPHL) we extend over the interval 1981Q1 to 1997Q4 by adjusting the NSA versions using the U.S. Census Bureau's X-13 ARIMA program. For total GDP (NACSGDPAQ.IPHL) we calculate as an identity, viz., the sum of those three series. The series carry a secondary source citation of "Moody's Analytics Calculated [Prior to 1998Q1]".

3. The 50 supplements (secondary source citation: "Moody's Analytics Adjusted") that we altered from SAAR to SA are as follows. The reduction is by 75%.
