Urban areas in OECD countries are classified as: \nlarge metropolitan areas if they have a population of 1.5 million or more; \nmetropolitan areas if their population is between 500 000 and 1.5 million; \nmedium-size urban areas if their population is between 200 000 and 500 000; and, \nsmall urban areas if their population is between 50 000 and 200 000. \nThis indicator is measured as a percentage of the national population.","reference-count":0,"publisher":"OECD","content-domain":{"domain":[],"crossmark-restriction":false},"short-container-title":[],"content-updated":{"date-parts":[[2024,2,23]]},"DOI":"10.1787\/b4332f92-en","type":"dataset","created":{"date-parts":[[2014,7,2]],"date-time":"2014-07-02T12:09:56Z","timestamp":1404302996000},"source":"Crossref","is-referenced-by-count":25,"title":["Urban population by city size"],"prefix":"10.1787","member":"1963","content-created":{"date-parts":[[2017,11,15]]},"container-title":["Population by region"],"original-title":[],"deposited":{"date-parts":[[2024,12,13]],"date-time":"2024-12-13T10:58:26Z","timestamp":1734087506000},"score":1,"resource":{"primary":{"URL":"https:\/\/data.oecd.org\/popregion\/urban-population-by-city-size.htm"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,11,15]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1787\/b4332f92-en","relation":{},"subject":[],"published":{"date-parts":[[2017,11,15]]}}}
