Megacity
A megacity is a very large city, typically with a population of more than 10 million people. The United Nations Department of Economic and Social Affairs (UN DESA) in its 2018 "World Urbanization Prospects" report defines megacities as urban agglomerations with over 10 million inhabitants. A University of Bonn report holds that they are "usually defined as metropolitan areas with a total population of 10 million or more people". Elsewhere in other sources, from five to eight million is considered the minimum threshold, along with a population density of at least 2,000 per square kilometre. The terms conurbation, metropolis, and metroplex are also applied to the latter. The total number of megacities in the world varies between different sources and their publication dates. The world had 32 according to EU Global Human Settlement Layer (in 2024), 33 according to UN DESA (in 2018), 39 according to the OECD, 44 according to ''Demographia'' (in 2023), and 45 according to ''CityPopu ...

Area Codes 213 And 323
Area codes 213, 323, and 738 are telephone area codes in the North American Numbering Plan (NANP) for the U.S. state of California. They are assigned in an overlay complex to a numbering plan area (NPA) that comprises, roughly, the area of downtown Los Angeles City, as well as several southeast Los Angeles County cities, such as Bell and Huntington Park. Area code 213 was one of the original North American area codes of 1947 and 323 was created in an area code split of 213 in 1998. This was the fifth split of 213 and left it serving only downtown Los Angeles and immediately adjoining neighborhoods. In 2017, the two NPAs were recombined in the overlay. Area code 738 was selected as an additional overlay area code, activated in November 2024. History In 1947, when the American Telephone and Telegraph Company (AT&T) devised the first nationwide telephone numbering plan and assigned the original North American area codes, the state of California was divided into three numberin ...

Mount San Antonio
Mount San Antonio, commonly referred to as Mount Baldy or Old Baldy, is a summit in the San Gabriel Mountains on the border of Los Angeles and San Bernardino counties of California. Lying within the San Gabriel Mountains National Monument and Angeles National Forest, it is the highest point within the mountain range, the County of Los Angeles, and the Los Angeles metropolitan area. Mount San Antonio's sometimes snow-capped peaks are visible on clear days and dominate the view of the Los Angeles Basin skyline. The peak and a subsidiary one to the west form a double summit of a steep-sided east–west ridge. The summit is accessible via a number of connecting ridges along hiking trails from the north, east, south, and southwest. Name The Tongva call the mountain ''Yoát'' or ''Joat'', which means ''snow'', and the Mohave call it ''Avii Kwatiinyam''. The name ''Mount San Antonio'' was probably bestowed by Antonio Maria Lugo, owner of a rancho near present-day Compton circa ...

Area Code 951
Area code 951 is a telephone area code in the North American Numbering Plan for western Riverside County in the southern part of the U.S. state of California. It was assigned in 2004 to a new numbering plan area (NPA) that was created by an area code split of area code 909. History In 1947, when the American Telephone and Telegraph Company (AT&T) devised the first nationwide telephone numbering plan and assigned the original North American area codes, the state of California was divided into three numbering plan areas: 213, 415, and 916, for the southern, central, and northern parts of the state, respectively. The area served by 213 extended from the Mexican border to the Central Coast. Starting in the 1950s, Southern California experienced rapid expansion of telephone service, requiring area code 213 to be split five times by 1998. The first split became necessary in 1951, when most of the southern and eastern portion, including San Diego and most of Orange County, was ...

Area Code 949
Area code 949 is a telephone area code in the North American Numbering Plan (NANP) for the U.S. state of California in southern Orange County. The area code was assigned on April 18, 1998, to a numbering plan area that resulted from a boundary change of area code 714 to exclude the southern cities of Orange County. Service area * Aliso Viejo *Costa Mesa (primarily the Westside) * Coto de Caza * Dana Point * Irvine (small portion in the 657/714 area code) * Ladera Ranch * Laguna Beach * Laguna Hills * Laguna Niguel * Laguna Woods * Lake Forest * Las Flores *Mission Viejo * Newport Beach * Rancho Mission Viejo * Rancho Santa Margarita * San Clemente * San Juan Capistrano * Santa Ana (mostly in the 657/714 area code) * Trabuco Canyon * Tustin (mostly in the 657/714 area code) The city of Costa Mesa is divided between area codes 949 and 714, being split at Wilson Street and along Newport Boulevard.

Area Codes 909 And 840
Area codes 909 and 840 are telephone area codes in the North American Numbering Plan for the far-eastern part of Los Angeles County, southwestern San Bernardino County, and a small portion of Riverside County in the U.S. state of California. Area code 909 was created on November 14, 1992, in an area code split of 909, and 840 was added to the numbering plan area to form an overlay complex effective February 23, 2021. While most of western Riverside County now uses Area code 951, some residents in Eastvale and Corona were allowed to keep the 909 area code after the split in 2004. History In 1947, when the American Telephone and Telegraph Company (AT&T) devised the first nationwide telephone numbering plan and assigned the original North American area codes, the state of California was divided into three numbering plan areas: 213, 415, and 916, for the southern, central, and northern parts of the state, respectively.

Area Codes 818 And 747
Area codes 818 and 747 are telephone area codes in the North American Numbering Plan (NANP) for the San Fernando Valley region of Los Angeles County in the U.S. state of California. Area code 818 was created in a split from area code 213 on January 7, 1984. On June 14, 1997, 818 was reduced in size to create a separate numbering plan area (NPA) for most of the San Gabriel Valley with area code 626. On May 18, 2009, area code 818 was overlaid with area code 747. History After the introduction of American telephone area codes in 1947, almost all of Los Angeles County used area code 213. During the 1980s and 1990s, the population and the demand for telecommunication services grew substantially in the Los Angeles metropolitan area, so that area code 213 came under resource pressure. In relief the numbering plan area was divided with several new area codes, including area code 818 and area code 310. Area code 818 entered service on January 7, 1984, making Los Angeles one of the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Area Codes 805 And 820
Area codes 805 and 820 are telephone area codes in the North American Numbering Plan (NANP) for the U.S. state of California. The numbering plan area (NPA) includes most or all of the counties of San Luis Obispo, Santa Barbara, Ventura, and the southernmost portions of Monterey County. 805 was split from area code 213 in 1957, and area code 820 was added to the NPA in 2018, creating an area code overlay. History Area code 805 was created in 1957, when one of the original North American area codes in California, 213, was reduced in size to provide more central office codes in the Los Angeles area. In 1998, the California-Nevada Code Administration (CNCA) determined that California was under "substantial number growth" which required exhaustion mitigation in the 805 numbering plan area, by splitting the eastern part of the NPA into a new plan area with the area code 661. The split was effective on February 13, 1999, for the San Joaquin Valley, Santa Clarita Valley, and Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Area Codes 760 And 442
Area codes 760 and 442 are telephone area codes in the North American Numbering Plan (NANP) for the U.S. state of California. These area codes serve an overlay complex that comprises much of the southeastern and southernmost portions of California. It includes Imperial, Inyo, and Mono counties, as well as portions of San Diego, Riverside, San Bernardino, Los Angeles, and Kern counties. Area code 760 was created on March 22, 1997, in a split of area code 619. Area code 442 was added to the same area on November 21, 2009. History Area code 760 was split from 619 in 1997, and 619 had been split from area code 714 in 1982. Within a decade of creation, the proliferation of cell phones and pagers left area code 760 under the threat of exhausting its central office prefixes. The initial relief plan was another area code split, with the San Diego and Imperial areas moving to a new 442 area code. However, this met with protests from businesses who did not want to change their numb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
