Caloocan

Caloocan, officially the City of Caloocan (Lungsod ng Kalookan; ), is a 1st class highly urbanized city in Metro Manila, Philippines. According to the 2020 census, it has a population of 1,661,584 people making it the fourth-most populous city in the Philippines.

Caloocan is divided into two geographical locations with a total combined area of 5,333.40 ha, a result of the expansion of Quezon City, which absorbed much of its territory. It was formerly part of the Province of Rizal in southern Luzon. It comprises what is known as the CAMANAVA area along with the cities of Malabon, Navotas and Valenzuela.

South Caloocan is bordered by Manila, Quezon City, Malabon, Navotas and Valenzuela. The presence of commercial and industrial activities combined with residential areas make it a highly urbanized central business district and a major urban center in the Northern District of Metropolitan Manila. North Caloocan shares its border with Quezon City and Valenzuela, Marilao, Meycauayan and San Jose del Monte in the province of Bulacan, and Rodriguez in the province of Rizal. It is composed of mostly residential subdivisions and extensive resettlement areas with scattered distribution of industrial estates mostly within road transit points and intersections.

Etymology
Caloocan as a toponym comes from the Tagalog words lo-ok that translates to "bay", sulok that means "corner" suggested by its location between the ends of the present-day Malabon and Tondo, Manila, and kalook-lookan (or kaloob-looban) meaning "innermost area". The city's name is colloquially spelled Kalookan.

There is a mixed preference over the preferred spelling of the city's name. Variation, and the apparent confusion over the spelling, came about during the early 1970s, when a resolution was adopted by the municipal board, requiring the city departments to use the name "Kalookan." However, execution of the resolution was interrupted due to martial law imposed nationwide in September 1972. In 1988, Councilor Aurora Asistio-Henson proposed Resolution No. 006, aiming to promote Filipino nationalism by enforcing the spelling "Kalookan" in all city departments and establishments. Despite this, the change was met with opposition from residents, business owners, and officials. Former representative and mayor Virgilio Robles deemed the move illegal, asserting that the city's name is spelled as "Caloocan" according to the city charter. Although confusion persists, the general inclination in the city is towards "Caloocan," as evidenced by the official logo and favored by many barangays, schools, and newspapers. However, some entities, like the Directories of the Philippines Corporation, prefer the spelling "Kalookan."

Spanish colonial era
Originally, Caloocan was the area where the old town of Tondo and Tambobong met, located along the shores of Dagat-Dagatan, a crescent-shaped inland lagoon to the west. The settlement along the shore was called "Aromahan", or "Espina" to the Spaniards, and was separated from Manila Bay by a narrow ridge from Tondo towards an opening in Kinabutasan leading to the sea.

By the late 1700s, the fishermen of Aromahan have expanded towards a hill east of Dagat-Dagatan. This naturally stony hill was called "Kaloogan", meaning "interior territory", which evolved from the old Tagalog word "loog" (synonymous with "loob" or "inside"). The "g" sound could have shifted to the "k" sound in Tagalog phonetics (e.g. baksak > bagsak) leading to the present name of the city. With Aromahan relegated to the periphery, this hilltop area was also settled by oppressed people from Tondo, becoming the new center of the community by 1802. To the east was a vast stretch of cogon-covered land. Eventually called "Kalaanan", meaning flat grassland in old Tagalog, this area is now generally known as Grace Park.

Caloocan became a municipality when it was separated from Tondo in 1815. Its original territory extended to the foothills of Marikina, San Mateo and Montalban to the east; Tinajeros, Tanza, and Tala rivers to the north; San Juan del Monte, San Francisco del Monte, Sampalok, Santa Cruz and Tondo in the south; and Dagat-dagatan and Aromahan to the west. The local government building was set up on the relatively well-settled portion just above Libis Espina. The old Aromahan chapel was finally abandoned and a new church was built facing the municipal hall. To escape the Spanish authorities, many from the area abandoned the town proper and sought refuge in the grasslands of Balintawak and Pugad-Lawin, in which the people fought the landlords of Hacienda de Maysilo for terrestrial rights, which went on for almost a hundred years.

The Philippine revolution
Caloocan is historically significant because it was the center of activities for the Katipunan, the secret militant society that launched the Philippine Revolution during the Spanish occupation of the Philippines. In a house in Caloocan, secret meetings were held by Andrés Bonifacio and his men, and it was in the city's perimeters where the first armed encounter took place between the Katipunan and the Spaniards. The revolution erupted after the "Cry of Balintawak" led by Andres Bonifacio against their oppressors on August 30, 1896.

American invasion era


In 1899, the people of Caloocan showed resistance to coming to terms with the Americans, who were bent on extending their supremacy over the country. The men of Caloocan fought the new invaders on February 23, 1899, however victory eluded the local troops on the pretext of Antonio Luna's rift with Emilio Aguinaldo's loyalists. The city then saw heavy fighting in the Philippine–American War, at the Battle of Caloocan and the Second Battle of Caloocan.

In 1901, under the American regime, Caloocan, previously a part of the province of Manila, became one of the municipalities of the newly established province of Rizal. Due to the consolidation of several municipalities in 1903, Novaliches, then an independent municipality, became part of Caloocan pursuant to Act No. 942, as amended by Act Nos. 984 and 1008 of the Philippine Commission.

Japanese occupation era
In 1942, Caloocan was one of the municipalities of Rizal merged alongside Manila and Quezon City to form the City of Greater Manila as an emergency measure by President Manuel L. Quezon. It regained its pre-war status as a municipality of Rizal when the City of Greater Manila was dissolved effective August 1, 1945.

Cityhood
In 1961, after Republic Act No. 3278 was approved by the Philippine Congress, a plebiscite was conducted. Caloocan was officially inducted into cityhood on February 16, 1962.

Caloocan remained a city of the province of Rizal until November 7, 1975, when it became a part of the National Capital Region or Metro Manila, by virtue of Presidential Decree No. 824.

Territorial changes
Caloocan once encompassed a much larger, contiguous area. The districts of Balintawak, La Loma and Novaliches were once part of Caloocan. Balintawak is a historic district because it was the original site of the "Cry of Pugad Lawin" (Unang Sigaw sa Balintawak) at a location called "Kang-kong" near Tandang Sora's house. Novaliches was an expansive sector with some hillsides that served as meeting places and hideouts for Andrés Bonifacio and the Katipunan.

During the American occupation, there was a consolidation of several municipalities. Caloocan annexed the neighboring town of Novaliches on October 12, 1903, as stated in the Act No. 942 of the Philippine Commission, bringing its total area to about 1,500 ha. When Commonwealth Act No. 502 created Quezon City in 1939, Caloocan ceded 1,500 hectares of land from the barrios or sitios of Bagubantay (Bago Bantay), Balintauac (Balintawák), Balingasa, Kaingin, Kangkong (present-day Apolonio Samson), La Loma, Malamig, Matalahib (present-day Santo Domingo), Masambong, Galas, San Isidro, San José, Santol and Tatalon. Instead of opposing the transfer, Caloocan residents willingly gave the land in the belief it will benefit the country's new capital city.

However, in 1949, Congress passed Republic Act No. 392, which redefined the Caloocan–Quezon City boundary. The barrios of Baesa, Sangandaan, Talipapâ, San Bartolomé, Pasong Tamó, Novaliches Proper (poblacion), Banlat (present-day Tandang Sora), Kabuyao, Pugad Lawin, Bagbag, Pasong Putik, which once belonged to Novaliches and had an area of about 8,100 ha, were excised from Caloocan. The remaining portion of the Novaliches is now called North Caloocan. This split Caloocan into two parts: a more urbanized southern section and a suburban-rural northern section, which is part of Novaliches.

In 1957, the sitio of Bagbaguin was separated from the barrio of Caybiga (Kaybiga) and converted into a distinct barrio known as Barrio Bagbaguin.

Reorganization attempts
Issues concerning budget and handling village governments led to attempts to restructure the city's barangays since late 1980s. A bill authored by city's 1st district representative Virgilio Robles, which aimed to reduce the barangays from 188 to 60—thirty in each legislative district—was approved as Republic Act No. 6714 on February 28, 1989. A plebiscite was held on March 10; with a turnout of only 10% of 384,981 registered voters, majority of the participated voters reportedly opposed the proposal.

On the other hand, residents of Bagong Silang (Barangay 176), currently the country's most populous barangay and is used to be a relocation site for informal settlers, have been appealing the partition of the barangay since 2013. On April 3, 2024, President Bongbong Marcos signed Republic No. 11993, which would divide the village into six. A plebiscite will be held within 90 days since the effectivity of the law.

Geography
Caloocan is divided into two non-contiguous areas with a total combined area of 53.334 sqkm. South Caloocan, with an area of 13.625 sqkm, is bordered on the south by Manila, on the east by Quezon City, on the west by Navotas, on the north-northwest by Malabon, and on the north by Valenzuela. North Caloocan, with an area of 39.709 sqkm, shares its border on the south-southeast by Quezon City, on the southwest by Valenzuela, on the north by Marilao, Meycauayan and San Jose del Monte in the province of Bulacan, and on the northeast by Rodriguez in the province of Rizal.

Topography
South Caloocan, where most commercial and industrial establishments are found, lies on generally flat and highly accessible land, with slopes ranging from 0–3%. The topography gradually changes from gently to moderately sloping to rolling along the North Luzon Expressway, with slopes ranging from 3–18%. The highest point at 35.00 m above sea level can be found in this area, while the lowest point is in the southern part of Dagat-Dagatan at about 0.993 m above mean sea level.

North Caloocan is characterized by gently to steeply undulating to rolling topography with slopes ranging from 3–18%, mostly seen in the northern and central portion, gradually transforming into a southward trend of flat lands down to the southwestern tip of the boundary. Being accessible to major roads, many industrial and residential subdivisions have been developed on this near-level land.

Geology
The geologic formation of the two portions of Caloocan varies in type and characteristics. and are specifically classified as quaternary alluvium, tuff and tuffaceous sediment, pyroclastic flow deposit, and conglomerates. The formation on the eastern half of Metropolitan Manila extending to the coastline of Manila Bay and including a greater part of South Caloocan is the quaternary alluvium, which consists of unconsolidated stream‐deposited sediments that include sand, silt, clay and gravel.

Eastward of South Caloocan, large areas consisting of tuff and tuffaceous sediment can be traced, spreading towards the whole eastern side of Metro Manila. Pyroclastic flow deposit or igneous rocks formed by the lithification of ash flow are likewise present in some northern fringes of South Caloocan and in most parts of North Caloocan. On the northeast borders of North Caloocan, conglomerate rocks were traced, crossing Tala Estate and extending to the province of Bulacan and the La Mesa Watershed.

Soil found in both areas of Caloocan predominantly falls under the Novaliches Series, covering 96% of the total land area of the city. The Novaliches Series is composed of reddish brown soil, friable in consistency and granular in structure. Spherical concretions are present in the subsoil and underneath is tuffaceous material of varying degrees of disintegration and weathering. This tuffaceous material is exposed by extensive erosion in some places.

Surface drainages
Caloocan has surface waters that either have natural courses (creeks and rivers) or were constructed to serve as drainages to remove excess water from soil surfaces. South Caloocan has about 5.0 km open drainage canals that serve mainly the reclamation area comprising Kaunlaran Village (Dagat-Dagatan Development Project) and nearly 11.3 km natural surface water coursing through the different natural river systems. These include the Tinajeros-Tullahan River along the Caloocan–Valenzuela boundary; Maligaya Creek within La Loma Cemetery and crossing Rizal Avenue Extension; Casili Creek which terminates in Estero de Maypajo, and Cantarilla/Panaca Creek along the Caloocan–Malabon boundary. In North Caloocan, all surface waters consist of natural streams, the longest being the Meycauayan-Marilao River dividing Caloocan and Bulacan. Others include the Bagong Silang River, Tala, Camarin, Pasong Malapad, and Bagumbong Creeks crossing multiple subdivisions, for 52.7 km long within the city's territorial boundaries.

Barangays
Currently, Caloocan has 188 barangays divided into 3 legislative districts. The 1st District is composed of 59 barangays, which include Barangays 1 to 4, 77 to 85, 132 to 164 in South Caloocan and Barangays 165 to 177 in North Caloocan. The 2nd District is composed of 118 barangays, which include Barangays 5 to 76 and 86 to 131, all in South Caloocan. 3rd District, which was created in 2021, includes 11 barangays in North Caloocan that were formerly part of the 1st District, which include Barangays 178 to 188.

The city uses a hybrid system for its barangays, further dividing the cities into 16 zones. Among the cities in Metro Manila, only Manila, Pasay and Caloocan implement the so-called "Zone Systems". A zone is a group of barangays in a district. Although a zone is considered a subdivision in the local government units, the people do not elect a leader for the zone in a popular election similar to the normal barangay or local elections as the system is merely for statistical purposes. Furthermore, all barangays have corresponding numbers but only a few—mostly in Caloocan's northern part—have corresponding names. However, the names of barrios and districts do not necessarily coincide with the perimeters of barangays. The barangays in southern Caloocan are generally smaller compared to their northern counterparts.

Barangay 176 or Bagong Silang is the most populous barangay in the country with a population of 261,729 people or 15.75% of the total population of Caloocan. This was due to the continuous influx of informal settler families through relocation programs since the 1970s. As a result, there have been calls by residents to subdivide the Bagong Silang into seven distinct barangays.

Barangay 76, meanwhile, is the least populous barangay in Metro Manila with a population of 2. It used to be an informal settlement and its entire 2.8 ha area is now predominated by retail buildings like Puregold Monumento and Araneta Square Mall.

Territorial disputes
Caloocan has two unresolved boundary disputes. Its dispute with San Jose del Monte, Bulacan, docketed as G.R. No. 142601 dated October 23, 2006, particularly encompasses portions of Pangarap Village and apparently Bankers Village 2 that are once part of Tala Estate. The lack of jurisdiction of the Commission on Settlement of Land Problems (COSLAP) resulted to the nullification of its decision. On the other hand, its dispute with Quezon City revolves around the latter's Barangay Baesa.

Moreover, the city governments of Caloocan and Malabon signed a memorandum of understanding (MOU) in 2014 to develop 80 ha of disputed land located within Caloocan's Libis Baesa area and Malabon's Barangay Potrero. The MOU preempted any court decisions on the dispute that began in 2001, when Malabon, upon its conversion to a highly urbanized city, took control over lands formerly under Caloocan's jurisdiction.

Demographics
As of 2020, the city has a population of 1,661,584 people, which makes it the fourth largest city in the Philippines in terms of population. Under the same census year, Caloocan South (Barangays 1 to 164) was recorded as having a population of 585,091, and Caloocan North (Barangays 165 to 188) was recorded with a population of 998,887. If the two districts were treated as separate cities, they still would have been among the largest in the country as of the 2015 census year, ranking fourth and 17th respectively in terms of population.

The population density of Caloocan (undefined PD/km2) surpasses that of the National Capital Region as a whole.

The 1st district of Caloocan was once the country's most populous legislative district, with 1.19 million persons as of 2015, prior to the creation of the 3rd district that was excised from it.

Most residents speak Filipino (Tagalog) and English, with considerable numbers speaking other languages and dialects of the Philippines.

Like many other places in the country, Caloocan is predominantly Roman Catholic. It is home to the seat of the Roman Catholic Diocese of Kalookan in its southern part, while its northern part is under the Roman Catholic Diocese of Novaliches. There is also a significant presence of Iglesia ni Cristo and other Protestant churches in the city.

Economy
Caloocan's 10th Avenue area is well known for its clusters of motorcycle dealers and motorcycle spare parts dealers. Among the major and famous streets are P. Zamora Street and A. Mabini Street.

Numerous banks have branches in the city such as BDO, EastWest Bank, MetroBank, PSBank, Maybank, Chinabank, Bank of the Philippine Islands, UnionBank, Philippine National Bank, Philippine Business Bank, Bank of Makati, Security Bank, Land Bank of the Philippines, Sterling Bank of Asia, Bank of Commerce, Philtrust Bank, Malayan Bank, Bank One Savings & Trust Corporation, WealthBank, Rural Bank of Caloocan, and Our Lady of Grace Credit Cooperative.

The city also has a number of shopping malls and stand-alone supermarkets and hypermarkets. In the southern part are SM City Grand Central (on the former site of Ever Gotesco Grand Central), Puregold Monumento, Victory Central Mall, Araneta Square, Uniwide Warehouse Club Monumento, LRT Caloocan Mall, SM Hypermarket Monumento, SM Center Sangandaan, 999 Shopping Mall Caloocan, and Walter Mart Caloocan. On the other hand, in the northern part are Zabarte Town Center, Holiday Island Mall, Metroplaza Mall, Primark Town Center Deparo, Primark Town Center Brixton, and SM City Caloocan. Savemore Market has three branches which are located in Kiko Camarin (Barangay 178), Zabarte inside Zabarte Town Center, Kaybiga and Primark Deparo. Puregold Price Club has seven branches in the north and five in the south.

Factories and industrial areas have also been built in various parts of Caloocan. Manufacturers are concentrated in the northern part, particularly in Bagumbong, Kaybiga, Llano, and Tala, while plastic and steel industries are concentrated in the southern part. Tala hosts the Victoria Wave Special Economic Zone, a 25 ha registered zone under the Philippine Economic Zone Authority.

NLEX Corporation, the concession holder of the North Luzon Expressway, is headquartered in Caloocan. The expressway's main section, NLEX Harbor Link, and NLEX Connector traverse through South Caloocan. Planned expressways such as the North Luzon East Expressway and North Access Link Expressway are slated to traverse Caloocan.

Local government
Caloocan, like other cities of the Philippines, is a local government unit whose powers and functions are specified by the Local Government Code of the Philippines. In general, as a city, Caloocan is headed by a mayor who heads the city's executive function and the vice mayor who heads the city's legislative function, which is composed of eighteen councilors, six from each of the city's three city council districts. For representation, the city has three districts, and therefore three representatives, in the country's House of Representatives.

The current Caloocan City Hall, situated in Grace Park East, serves as the city's seat of government. Located in a rectangular lot between 8th and 9th Streets and 8th and 9th Avenues, it replaced the old city hall built in 1952 on A. Mabini Street, across from San Roque Cathedral-Parish, now occupied by 999 Shopping Mall Caloocan. The Caloocan City Hall North, situated in Camarin along Zapote Street, serves the northern part of the city. It is currently undergoing reconstruction since 2023.

Transportation
The LRT Line 1 has two stations in the southern part of the city, namely: Monumento and 5th Avenue. Philippine National Railways (PNR) also has a line, with its terminal at Samson Road, and passes through Caloocan railway station (the first railway station built in the city), 10th Avenue railway station, and 5th Avenue railway station. The currently under construction MRT Line 7 has also two under-construction stations located at the northern part of Caloocan, namely: Sacred Heart and Tala. The North–South Commuter Railway, another currently under construction rail transit system, will replace the existing PNR Metro Commuter Line and will have one station at Caloocan.

The city has an extensive network of roads, the most prominent being Epifanio de los Santos Avenue, which begins in the Monumento area. Quirino Highway, which connects Quezon City and eastern Bulacan, also traverses the northern part of Caloocan. The North Luzon Expressway's Operations and Maintenance Center and the motorway's Balintawak toll barrier are in the southern part of Caloocan. NLEX Harbor Link, its extension that connects it towards Navotas and Port of Manila, and the NLEX Connector project that connects Harbor Link with the City of Manila and Skyway also traverse Caloocan. The northern end of Skyway, which connects the North and South Luzon Expressways, is also found near NLEX's Balintawak toll plaza, with a possible connection to Northern Access Link Expressway, a future toll road to the New Manila International Airport.

Bus line Victory Liner Incorporated has its headquarters and terminal along Rizal Avenue Extension near the Monumento station.

Landmarks


The city's most celebrated landmark is the monument to the revolutionary Andrés Bonifacio, which stands on a roundabout where EDSA, MacArthur Highway, Samson Road, and Rizal Avenue Extension intersect. The memorial was erected in 1933 and consists of an obelisk with sculptures by National Artist Guillermo Tolentino. The monument marks the very first battle of the Philippine Revolution on August 3, 1896. Recent renovations have been made on the environs of the monument, including the Bonifacio Circle, its former site, and the Caloocan stretch of EDSA, which is 100 m away from the landmark. The whole area is known as 'Monumento'.

Other sites of historical importance identified by the city government include a lot in P. Zamora Street where the wife of Katipunan leader Andrés Bonifacio once resided; the heritage house of Gertrudes Sevilla, the owner of which is the nephew of Gregoria de Jesús; Santa Quiteria Church in Baesa; and Our Lady of Grace Parish in 11th Avenue; La Loma Cemetery, the oldest cemetery in Manila; and Thai To Taoist Temple along 6th Avenue. In addition, the city's District Office of the Bureau of Internal Revenue is along EDSA.

Police
The Caloocan City Police Station is under the parent agency National Capital Region Police Office's Northern Police District of the Philippine National Police. They were once recognized as the best police station for their contribution to the drug war during the administration of President Rodrigo Duterte.

However, the whole Caloocan city police force was recently sacked after a series of crimes, including killings and robberies, were committed by its members. However, instead of dismissing the erring police officers, they were scheduled to be retrained by then Philippine National Police Chief Ronald dela Rosa.

Education
The city's lone public university is the University of Caloocan City (formerly Caloocan City Community College in 1971 and Caloocan City Polytechnic College in 1975). Other educational institutions offering tertiary education include University of the East Caloocan, Manila Central University, La Consolacion College-Caloocan, and La Consolacion College – Novaliches, Access Computer College Caloocan, AMA Computer College-Caloocan, STI Academic Center Caloocan, among others.

The Schools Division Office (SDO) - Caloocan City oversees 89 public schools and a number of private schools within the city, up to secondary level. Notable public schools are Caloocan National Science and Technology High School (North Caloocan's first-ever science and technology high school), Caloocan City Science High School, Caloocan City Business High School, and Caloocan High School. Private institutions such as the Philippine Cultural College (Annex), Saint Benedict School of Novaliches, the Diocese of Kalookan's St. Gabriel Academy, St. Mary's Academy of Caloocan City, Notre Dame of Manila, and Santa Elena School of Novaliches are also located in the city.
