Car ownership in the metropolitan area

The data includes the car ownership data of Helsinki Metropolitan Area for the years 2000, 2002, 2005, 2007, 2010, 2012, 2013, 2015, 2017 and 2020. Years 2000-2017 include the data from Helsinki, Espoo and Kauniainen and the year 2020 includes the data from Helsinki, Espoo and Vantaa. The produced dataset is based on the Finnish Environment Institute’s YKR data. The regional divisions of the calculated data vary depending on the city: in Helsinki, the division is based on districts and in Vantaa, Espoo and Kauniainen on the division of statistical areas. The dataset has been composed as follows: 1. Each municipality’s squares (= centres of the squares) have been separated from the data for different years according to the municipality code. 2. Information about the area division has been attached to the centres of the squares based on location (partly manually on the edges of the areas). 3. Column data has been summed up based on the area division. 4. Tables have been cleaned up by deleting redundant data and fading out some data, such as “less than 10” cases, for privacy reasons. **The dataset includes the following attributes** — ak_yht total number of households — ak_1 Households, number of persons 1 — ak_2 Households, number of persons 2 — ak_3 Households, number of persons 3 — ak_4 Households, number of persons 4 — ak_5 Households, number of persons 5 — ak_6 Households, number of persons 6 — ak_7 Households, number of persons 7+ — henk_yht total persons — ak_18v Households with children under 18 years old — autoja_1 Number of households with 1 car — autoja_2 Number of households with 2+ cars — also unique identifiers, place names, etc. **Things to note about using the dataset**: For privacy reasons, information is not available on all squares of the YKR dataset used as source data. The produced dataset is therefore not fully accurate.
