I made three code changes in the main table to reflect this latest update.The update also changes the status of some of the independent cities.It reconciles some name and code changes that were made incorrectly when the GEC document was recompiled.I have already noted the difficulty I had with discrepancies in earlier updates.Since 1972-09-24, the provinces have been grouped into regions.The regions have no government of their own, but are for administrative convenience.Municipalities and chartered cities are subdivided into barangays.
For most purposes it should suffice to say that Shariff Aguak and Sultan Kudarat are co-capitals.Some chartered cities have become highly urbanized cities; others have become independent component cities. Short has prepared a database called Phillipine Geographies, Areas and Codes (PGAC). National Geospatial-Intelligence Agency issued a document in 2010-04 titled "Geopolitical Entities and Codes" (GEC), intended to replace the discontinued federal standard FIPS 10-4.Update 11 to Geopolitical Entities and Codes (formerly FIPS 10-4) is dated 2013-04-30. It covers regions, provinces, municipalities, barangays, and other civil and ecclesiastical geographies. There have been two updates to this document that affect the Philippines: Update 8 (2012-05-01) and Update 10 (2012-12-31).Edward Jassen dela Pea sent me a pdf file containing the data for the 2007 Philippine census. There are also some minor spelling changes, and the code for one of the old regions is changed.I have incorporated the populations in the table below (after checking that they agree with data on the Philippines National Statistics Office site). ISO 3166-2 Newsletter Number I-2 was published on 2002-05-21. The new ISO codes for provinces appear in the table below. The islands became an insular area of the United States.
