9.1.1 Proportion of the rural population who live within 2 km of an all-season road



The indicator measures the share of the rural population living within 2 km of an all-season road in a given region in the total rural population of that voivodship/powiat in 2020.

National, regional, district and communal roads with bituminous surfaces (asphalt) were considered as roads that meet the condition of all-season road. Due to the nature of the indicator, the data does not apply to cities with powiat status (marked with grey areas on the map).

The higher the value of the indicator, the greater the percentage of the rural population in a given voivodship or powiat has access to all-season road at a distance of 2 km from their place of residence.

Here you can find a set of context indicators, the data for which come from official statistics of Statistics Poland. The purpose of context indicators is to complement the results of experimental SDG statistics, deepen information on the monitored phenomena and provide support in assessing progress in implementing sustainable development.

How did we calculate the indicator?

In order to calculate the indicator, the following stages were carried out:

Grafika ludzika

1. Based on data from the PRG database, so-called masks (isolated fragments of the area) for the analysis of rural areas were determined (by excluding urban areas from the analysis).

2. Roads that met the all-season condition (accessibility throughout the year) were designated from the BDOT10k database.

3. A road buffer with a radius of 2 km has been designated.

4. Based on data from the WorldPop database, the population within the road buffer and the total population for rural areas were calculated.

5. Based on data from the p. 4, the indicator 9.1.1. Proportion of the rural population who live within 2 km of an all-season road was determined.

Detailed information on calculations based on the UN methodology can be found in the indicator metadata.

What sources were used to calculate the indicator?

The indicator was calculated based on the methodology proposed by the UN using data from three sources: Topographic Objects Database (BDOT10k) and National Register of Boundaries (PRG) databases maintained by Head Office of Geodesy and Cartography of Poland (GUGiK) and the WorldPop database.

Topographic Objects Database (BDOT10k) is a vector database containing the spatial location of topographic objects along with their basic descriptive characteristics, corresponding in detail to a traditional topographic map on a scale of 1:10000. The database contains information about the type and category of roads, the type of road surface, as well as the width and length of the road.

Earth graphic

National Register of Boundaries (PRG) is an official database providing basis for other spatial information systems. The PRG register collects data concerning area of the whole country, including: boundaries and areas of the units of the three-tier administrative division of Poland (i.e. voivodships, powiats, gminas).

The WorldPop database contains high-resolution data on the distribution of the world's population. The datasets show the estimated number of people living in each grid cell as a 100x100m raster.

What is the meaning of the indicator for sustainable development?

Providing rural residents with access to all-season road infrastructure increases development opportunities in rural areas. Improved road conditions reduce transportation costs and travel time, and increase employment opportunities and occupational mobility of rural residents. All-season access to roads also contributes to improving the quality of life of rural residents, increasing their access to public services and preventing social exclusion.

Applications for local government units

The indicator data provide information that can be used for policy making, including transport and infrastructure policies, especially in planning the development of the road network in rural areas.
