The Pacific was divided into two "Theaters" of Operations - the Central Pacific, and the Southwest Pacific. This was done mostly because MacArthur had retreated to Australia after Japan conquered the Philippines, and as a former commanding general of the US Army, a prestigious command had to be carved out for him. So, MacArthur commanded in the Southwest Pacific, fighting in the New Guinea area and the Philippines. Navy Admiral Chester Nimitz commanded in the Central Pacific, from his HQ in Hawaii, where he was also commander of the US Pacific Fleet.
The Pacific Fleet, which is part of the United States Navy, primarily operates in the Pacific Ocean and is responsible for naval operations in that region. However, if you're inquiring about the percentage of the world's population living within the geographic boundaries of nations that fall under the Pacific Fleet's area of operations, it varies widely depending on the specific countries considered. Countries around the Pacific, such as China, Japan, and the United States, have large populations, but a precise percentage would require a specific definition of the area and current population statistics.
Japanese Central China Area Army was created in 1937.
California is part of the Pacific region of the United States.
The 7th Fleet operated in the zone known as the Southwest Pacific Area (SoWesPac), which was under the command of General Douglas MacArthur. The area encompassed Australia, New Guinea, the Netherlands East Indies, Borneo, French Indo-China, the Philippines, and the South China Sea. The main strength of the 7th Fleet was concentrated in battleships, escort carriers, and submarines to support MacArthur's campaigns in the area.
