Connecting statistical data from NSI with addresses
Data from the National Statistics Institute’s latest 2011 census was tied to every building in the city. Automated geocoding (address finding) tools in GIS have been employed, subsequently eliminating errors from incorrect data. As a result, we have demographic information (number of inhabitants, gender, age group) for each dwelling, type of heating (electricity, heating, firewood, coal, oil, gas), whether they have central sewage provision, etc. This data, structured in GIS, can be used for a number of other analyzes and projects. For instance - population density, access of Sofia residents to parks and gardens, bicycle infrastructure and more.
