This table provides metadata for the actual indicator available from Turkey statistics closest to the corresponding global SDG indicator. Please note that even when the global SDG indicator is fully available from Turkey statistics, this table should be consulted for information on national methodology and other Turkey-specific metadata information.
| Target name | By 2030, provide universal access to safe, inclusive and accessible, green and public spaces, in particular for women and children, older persons and persons with disabilities |
|---|---|
| Indicator name | Average share of the built-up area of cities that is open space for public use for all |
| Global / Proxy indicator | Global |
| Description of indicator | The indicator aims to monitor successfully the amount of land that is dedicated by cities for public space (open spaces and streets). Cities vary considerably in size, history, development patterns, designs, shapes and citizen’s attitudes towards public spaces. Measuring how much public space a city has is only one part of measuring whether residents actually benefit from the space. |
| Unit | (%) |
| Available disaggregation | Province level |
| Calculation | Public open space (m2) / Total urban area (m2) * 100 |
| Comparability | Comparable over time - Produced in full compliance with global metadata. |

Landsat imagery is used to identify and classify the built-up pixels into 3 types depending on the share of built-up density (urban-ness) in a 1-km2 circle of a given building (walking distance radius of about 564 meters around a given building): • Urban built-up area: pixels where the walking distance circle has a built-up density greater than 50%. • Suburban built-up area: pixels where the walking distance circle has a built-up density between 25%-50%. It also includes subdivided land, whether it is wholly unbuilt or not. • Rural built-up area: pixels where the walking distance circle has a built-up density of less than 25% and that are not on subdivided land. Urban extent is defined as the total area occupied by the built-up area and the urbanized open space. The built-up area is defined as the contiguous area occupied by buildings and other impervious surfaces. For measurement of indicator 11.7.1, the elements which can be considered as open public space include: • Parks and civic parks • Recreational areas • Squares and Plazas |
