The municipality of Oslo has a population of 717,710 as of 1 January 2024.<ref name="auto">{{cite web |date=27 February 2020 |title=2020-02-27 |url=https://www.oslo.kommune.no/statistikk/befolkning/befolkningsutviklingen-i-oslo-gjennom-2023 |url-status=live |archive-url=https://web.archive.org/web/20200301184423/https://www.ssb.no/en/befolkning/statistikker/folkemengde/kvartal/2020-02-27 |archive-date=1 March 2020 |access-date=1 March 2020 |website=ssb.no |language=en}}</ref> The urban area extends far beyond the boundaries of the municipality into the surrounding [[counties of Norway|county]] of [[Akershus]] (municipalities of [[Asker]], [[Bærum]], [[Lillestrøm Municipality|Lillestrøm]], [[Enebakk]], [[Rælingen]], [[Lørenskog]], [[Nittedal]], [[Gjerdrum]], [[Nordre Follo]]); being, to a great degree suburbs of Oslo making up approximately 500,000 of the population of the [[Greater Oslo Region|greater Oslo region]]. The total population of this agglomeration was 1,546,706 in 2023.<ref name="SSB-2023" /> The city centre is situated at the end of the [[Oslofjord]], from which point the city sprawls out in three distinct "corridors"—inland north-eastwards, and southwards along both sides of the fjord—which gives the [[Urban area|urbanized area]] a shape reminiscent of an upside-down reclining "Y" (on maps, satellite pictures, or from high above the city).

To the north and east, wide forested hills (''Marka'') rise above the city giving the location the shape of a giant [[amphitheatre]]. The urban [[List of municipalities of Norway|municipality]] (''bykommune'') of Oslo and county (''[[Counties of Norway|fylke]]'') of Oslo are two parts of the same entity, making Oslo the only city in Norway where two administrative levels are integrated. Of Oslo's total area, {{cvt|130|km2|sqmi}} is built-up and {{cvt|9.6|km2|sqmi}} is agricultural. The open areas within the built-up zone amount to {{cvt|22|km2|sqmi}}.<ref>{{cite web |url=https://www.ssb.no/kommunefakta/oslo |title=Kommunefakta Oslo |publisher=Ssb.no |date=1 January 2022 |access-date=28 June 2022 |archive-date=17 January 2021 |archive-url=https://web.archive.org/web/20210117001140/https://www.ssb.no/kommunefakta/oslo |url-status=live }}</ref>

The city of Oslo was established as a municipality on 3 January 1838 (see [[formannskapsdistrikt]]). It was separated from the county of [[Akershus]] to become a county of its own in 1842. The rural municipality of [[Aker, Norway|Aker]] was merged with Oslo on 1 January 1948 (and simultaneously transferred from Akershus county to Oslo county). Furthermore, Oslo shares several important functions with Akershus county.
