About this data
This dataset provides population counts by 5-year age groups and sex for OECD Functional Urban Areas (FUAs) and cities. Data sources and methodology Population by age and sex data is collected at the level of small administrative units (e.g. municipalities) and aggregated at the FUA and city level. The correspondence table between SAUs and FUAs/cities is available in parquet and csv format. Defining FUAs and cities The OECD, in cooperation with the EU, has developed a harmonised definition of functional urban areas (FUAs) to capture the economic and functional reach of cities based on daily commuting patterns (OECD, 2012). FUAs consist of: A city β defined by urban centres in the degree of urbanisation, adapted to the closest local administrative units to define a city. A commuting zone β including all local areas where at least 15% of employed residents work in the city. The delineation process includes: Assigning municipalities surrounded by a single FUA to that FUA. Excluding non-contiguous municipalities. The definition identifies 1 272 FUAs and 1 269 cities in all OECD member countries except Costa Rica and four accession countries.
