Population

The Population data category provides information about living and working populations with selected filters.

Overview

Population

To get started:

  1. Go to the Main or Data tab.
  2. Select the Population data category.
  3. On the Filters tab, select a Territory.
  4. Set the remaining filter parameters if necessary.

The data is visualized on the map as centroid points: the centers of the object geometries. Results are available in two variants:

  • Statistics: general statistics about the sample. Include:

  • Total and average count of the living population.

  • Total and average count of office workers.

  • Chart with the distribution of population. Displayed if both categories are selected.

  • Results: general information about the population and a list of buildings in which the population lives and works. When selecting a building from the list:

    • Information about the building and the count of living and work population is displayed in a card.
    • The location of the building is indicated on the map.

To save this data sample and customize its visualization (e.g., as a heatmap), click Create layer.

Filters

For the Population category, the following filters are available:

  • Territories: country and city. You can select no more than 5 cities per country. There may also be restrictions depending on the tariff. Required for selection.

  • Nearby: limiting the data sample by territorial availability. Possible options:

    • Off: default value.
    • Radius: circle with a radius from 10 to 100000 m is drawn around a point in the center of the map. The default value is 10000 m.
    • Path: area that is accessible by car or on foot within 5 to 30 min is drawn around a point in the center of the map. The default value is 15 min.

    To change the area, drag the center point to the necessary area of the map.

  • Living population: count of the living population in the building.

  • Working population: count of the working population in the building.

To reset the filter, click Cross icon next to the filter name. To reset all filters, click Reset filters at the bottom of the tab.

How the data is collected?

Algorithm of counting the living population contains the following steps:

  1. Calculation of the living area of buildings on a given territory.

    The Urbi directory provides information on buildings on the map. For further prediction of living population, buildings are classified as follows:

    • Buildings with a known number of apartments (for example, a building with multiple floors). Calculation of the living area is based on the number of apartments and the apartment area norm in the given city.
    • Buildings with no information on apartments. Calculation of the living area is based on the building geometry. Non-residential areas (parking lots, non-residential first floors, commercial areas on multifunctional complexes) are excluded.
    • Private houses. Normally, one family lives in each building. This information is sufficient for further calculation and the living area is not used.

  2. Prediction based on housing standards:

    • For private houses: average size of a family.
    • For other house types: the living area size (calculated on the previous step) divided by the standard of the living area for one person in the given country or city.

    Information on housing standards (average apartment square, average family size, and more) is provided by the statistics department of the country, statistics agencies, or other public sources.

  3. Correction based on the population census.

    This step helps correct inaccurate values for a city or district if many inhabited buildings (for example, a high-rise apartment building not yet put into operation) are located in the area or the population density significantly deviates from the average numbers.
