Tiivistelmä: The delineation of localities is the basic spatial classification of settlement structure. The delineation of localities is an essential basis in planning, steering and monitoring land use. The localities have been delineated by the Finnish Environment Institute. Overall, localities identify densely populated areas at a national level, but the outlined locality settlements can be divided further into densely built locality settlements and sparsely built locality settlements. This classification divides the areas of localities based on grid-level area density, resulting in 250 x 250 meter accuracy. Densely built locality settlements represent areas where the area density corresponds in general to already locally planned areas inside localities. Whereas sparsely populated locality settlements correspond generally to areas within localities with low area density and no local detailed plans. The delineation of sparsely built locality settlements may include incomplete planned areas nearby areas of locally planned land, narrow settlements along roads or functionally linked village-like settlements near densely built locality settlements. Densely built locality settlements include the 250 x 250 meter cells that form an area density of at least 0,02 calculated from surrounding eight cells. The remaining locality cells are categorized as areas of sparsely built locality settlements. In this context, locality is used to refer to densely populated areas of at least 200 residents. The delineation of localities is produced on the basis of the Monitoring System of Spatial Structure and Urban Form (YKR), which is a spatial grid-based information system maintained by the Finnish Environment institute. The YKR-based statistical delineation method of localities is comparable both in space and time, which makes it possible to monitor the expansions of the area of localities without the errors brought on by the changes in the method used for delineation. The YKR method also results in a more compact delineation of the localities than the one produced by using the Nordic standard. The delineation produced by this method is also used by Statistics Finland. The Finnish title of this dataset is Harvat ja tiheät taajamat. The dataset belongs to SYKE’s open data collection (CC BY 4.0).

Käyttötarkoitus: Densely and Sparsely built locality settlements are produced by SYKE to support monitoring of urban form and spatial structure. The division to densely and sparsely populated areas is one of the basic divisions used in the Monitoring System of Spatial Structure and Urban Form (YKR).

Sijainnillinen ja ajallinen kuvaus: The latest YKR Densely and Sparsely built locality settlements dataset is available from SYKE's open information service. It is updated on a yearly basis. The dataset does not include information on population and workplaces. However, the full dataset including all the information is available for the internal use in environmental administration. For internal use the dataset is also available from 1990 onwards at five year intervals and from 2010 onwards on a yearly basis.

Historiatiedot: The delineation of densely and sparsely built locality settlements is based on the delineation of localities by the Finnish Environment Institute. The main datasets used in the delineation of localities have been: - the number of buildings (agriculture buildings and holiday homes excluded) - the floor area of buildings (agriculture buildings and holiday homes excluded) - population and - the relations between the variables mentioned above measured in distance Through this delineation procedure, it is ensured that following characteristics of localities are paid attention to: - Single buildings with large floor areas that are located at an edge of a densely populated area and are functionally part of the area should be included in the delineation of localities. - Elongated and narrow settlements along rivers, roads or shorelines that are sparsely populated and resemble rural areas should be excluded from the delineation of localities. - Large open areas inside the localities should be excluded from the delineation (for example large unbuilt areas, sparsely built areas, fields, forests, waters). The delineation of localities is carried out using the statistical grid (250 x 250 m) of building stock and population. The grid cells that fulfill the following three conditions concerning population, number of buildings and floor area are selected as the base for the delineation of localities: 1. The number of buildings in the cell must be at least two OR the gross floor area of the building stock at least 300 square meters. 2. The total number of buildings in cells located within one kilometer from the cell in question must be at least 40. 3. The gross floor area of the buildings located in the cell and its eight neighboring cells must be at least 1500 square meters. The cells meeting the mentioned three criteria are buffered 250 meters outwards and dissolved to form continuous polygons. The polygons are then buffered again inwards 250. The last buffer is used to select cells from the original 250 x 250 meter grid: the cells that have their centroid inside the buffered zone are selected. The selected cells that share an edge or a corner are dissolved to form the same polygon. Finally the population for the formed polygons is calculated. Polygons with a total population of 200 or more are selected and classified as localities. The area of the created localities is then divided into densely built locality settlements and sparsely built locality settlements based on area density. Locality grid cells that form an area density more than 0.02 with its surrounding eight cells are classified as densely built locality settlements. Grid cells that form an area density less than 0.02 with its neighboring cells are classified as sparsely built locality settlements.
