Southern Tagalog was the largest region in the Philippines in terms of both land area and population. The 2000 Census of Population and Housing showed the region having a total of 11,793,655 people, which comprised 15.42 percent of the 76.5 million population of the country at that time.
Region IV or Southern Tagalog was divided into Calabarzon and Mimaropa, upon the issuance of Executive Order No. 103, dated May 17, 2002, by then-President Gloria Macapagal Arroyo. Additionally, the province of Aurora was moved to Region III (Central Luzon).
