In 1950, the population of Port Harcourt was 59,752. Port Harcourt has grown by 150,844 since 2015, which represents a 4.99% annual change.
The colonial administration of Nigeria created the port to export coal from the collieries of Enugu located north of Port Harcourt, to which it was linked by a railway called the Eastern Line, also built by the British.
Port Harcourt's economy turned to petroleum when the first shipment of Nigerian crude oil was exported through the city in 1958. Through the benefits of the Nigerian petroleum industry, Port Harcourt was further developed, with aspects of modernization such as overpasses, city blocks, and taller and more substantial buildings. Oil firms that currently have offices in the city include Shell and Chevron with Agip Company.
The current mayor is Ezebunwo Ichemati.
Etymology The port was built in 1912, but not given a name until August 1913, when the then Governor of Nigeria, Sir Frederick Lugard named it "Port Harcourt" in honor of Lewis Harcourt, 1st Viscount Harcourt, then the Secretary of State for the Colonies. The native Ikwerre name for the area is Rebisi (the traditional kingdom)https://internationalpolicybrief.org/wp-content/uploads/2024/04/ARTICLE-3.pdf.
History
Port Harcourt was founded in 1912 by Frederick Lugard, governor of both the Northern Nigeria Protectorate and the Southern Nigeria Protectorate.Falola, Toyin, Ann Genova, Matthew M. Heaton (2018), Historical Dictionary of Nigeria, Rowman & Littlefield, USA, p. 341.African Affairs, Volume 71 (1972), p. 274. Its purpose was to export the coal that geologist Albert Ernest Kitson had discovered in Enugu in 1909. The colonial government caused the people of Diobu to cede their land, and in 1912 the building of a port-town was started. Other villages that were later absorbed into the city included Oroworukwo, Oromeruezimgbu, Nkpogu, and Rumuomasi; In the creeks to the south of the original port were the fishing camps and grounds of the Rebisi-ikwerre People-Ikwerre group.
During the First World War, Port Harcourt was used as a point for military operations against the Central Powers in German Kamerun. After the discovery of crude oil in Oloibiri in 1956, Port Harcourt exported the first shipload from Nigeria in 1958. Port Harcourt became the centre of the Nigerian oil economy and it subsequently reaped benefits of its associations with the petroleum industry by undergoing modernization and urbanization. Port Harcourt's growth is further due to its position as the commercial centre and foremost industrial city of the former Eastern Region; its position in the Niger Delta; and its importance as the centre of social and economic life in Rivers State. After the Republic of Biafra seceded from Nigeria in 1967 Port Harcourt fell to Nigerian forces on 19 May 1968. From an area of in 1914, Port Harcourt grew uncontrolled to an area of in the 1980s.
Geography
The main city of Port Harcourt is the Port Harcourt City in the Port Harcourt local government area, consisting of the former European quarters now called Old GRA and New Layout areas. The urban area (Port Harcourt metropolis), on the other hand, is made up of the local government area itself and parts of Obio-Akpor and Eleme accordingly.Ogbonna, D. N. / Amangabara, G. T. / Ekere, T. O.: "Urban solid waste generation in Port Harcourt metropolis and its implications for waste management", Management of Environmental Quality: An International Journal, Volume: 18 Issue: 1; 2007 Port Harcourt, which is the current capital of Rivers State, is highly congested as it is the only major city of the state. In 2009, a law was passed by the Rivers State House of Assembly and Governor Amaechi's administration to spread development to the surrounding communities as part of the effort to decongest the Port Harcourt metropolis. The Greater Port Harcourt region, spans eight local government areas that include Port Harcourt, Okrika, Obio-Akpor, Ikwerre, Oyigbo, Ogu–Bolo, Etche and Eleme. Its total population was estimated at 2,000,000 as of 2009, making it one of the largest metropolitan areas in Nigeria. But that number has greatly increased according to recent studies.

Environmental concerns
Air pollution
Residents of the city have been experiencing particle (soot) pollution since the last quarter of 2016. Text was copied from this source, which is available under a Creative Commons Attribution 4.0 International License. Residents state their clothes and everything outside is covered with a layer of black soot. Official PM2.5 information from the state's environmental commissioner, Roseline Konya, states a high reading of 270 micrograms per cubic meter for air pollution in the city from a 2016 sampling. According to the U.S. Environmental Protection Agency's (EPA) index air quality index (AQI), a reading of 0 – 50 is good, readings between 200 – 300 which Port Harcourt falls under is considered unhealthy for everyone and E.P.A advises residents of such areas to avoid heavy and prolonged exertion, and move activities indoors. "For a 15-month period ending in June ... air quality was in the unhealthy range on 240 days, with 85 days ranking very unhealthy, and 13 days as hazardous."
The increased deterioration of ambient air quality led to a state protest in February 2017. There were experiences of black soot settling in nostrils, on cars, floors, roofs, windows, bathtubs, bathrooms, kitchen sinks and household furniture surfaces resulting in frequent cleaning of affected surfaces and places. potable, domestic and rainwater were equally affected. Abuloma, Iwofe, Rupokwu, Okrika, and Woji were mostly affected with other areas such as Rumuigbo, Eleme, and Oyigbo Local Government Councils, as well as Ogoni.
The covering of the haze of soot in most parts of the city has resulted in visibility impairment by PM2.5, soil, and water deposition, and disruption in ecosystem diversity. This also made the city dwellers spend more time indoors than outdoors. Residents in cities such as Rumosi and Rumuodumanya in Obio/Akpor Council have relocated to other safe cities leading to a decline in business activities.
The Ministry of Environment took action by analysing air samples from various sites in the city and found out to be 11 times higher than WHO specifications for PM2.5 and PM10. This non-compliance was tackled by shutting down the Chinese Government Company (CGC), H&H Engineering Company, and AUC Asphalt Company located in the Aluu community, found to be the location of high volume discharge of emissions thereby contravening environmental regulations. Illegal refineries, burning of tires, gas flaring, liquefied natural gas (LNG) operations and processes, petro-chemical companies and refineries were other suspected sources of soot pollution.
Residential areas
Some of Port Harcourt's more popular and well-known residential areas are known as Port Harcourt Township (or just "Town"), GRA (Government Reserved Area) phases 1–5, Elekahia, Rumuomasi, D-line, Elelenwo, Eliozu, Iboloji, Ogbunabali, Rumuola, Rumuigbo, Mgbuoba, Diobu, Woji, Amadi Flats, Umuchitta, Rumuokoro and Borikiri.
