4.2 Database description

Regularly updated and analytically verified machine-readable datasets for the City Digital Twin Data Hub include 174 million values of social and economic development indicators and parameters.

The database includes the following sections:

• reference data
  
• Social & Economic Development Indicators (SED) of territories
  
• matrices of socio-economic ties (structural data)
  
• database of investment projects, with technical and economic indicators and socio-economic effects of investment projects (management decisions), portfolios, and programs

The indicators are given in the following analytical measurements:

• territories: a country, federal district, region, agglomeration, municipality, object address
  
• time periods (years, including project start and end dates)
  
• indicators (demographic, economic, social, etc.; basic, relative, and generalized; cumulative, instantaneous, and growth rates)
  
• for economic indicators: industries and budget items
  
• for demographic indicators: gender and age structure
  
• scenarios (actual, reconstructed, estimated, target, and median)
  
• versions: indicating the date of loading and estimation
  
• data sources and recipients

The actual and reconstructed indicators of social and economic development serve as the basis for calculating (calibrating) the following matrices with parameters:

• multipliers (intersectoral balances)
  
• tensions (inter-territorial balances)
  
• correlation (sensitivity)
  
• conversion of indicators into their main components, providing connectivity and consistency of indicators

The prepared matrices are used to build forecasts, conduct What-if analysis and answer “What is needed” questions, assess impact, and form agreed parameters for development plans.

The datasets are collected from open sources and contain sets of actual SED indicator values since 2000 (for regions), since 2009 (for municipalities), and since 2012 (for sectoral indicators) and forecast indicator scenarios up until 2050 * for the Countries as a whole * for 2,300 municipalities * for 1,200 cities * for 22,000 settlements * for 128 industries
