In which condition are the buildings of the district? How is the quality of the infrastructure in the districts Which infrastructure will have a serious shortfall in capacity or overcapacities in the next years? Which infrastructures should be pooled because of spatial proximity? Which infrastructures should be maintained because of easy accessibility? Important Questions Concerning Socioeconomic Factors, Infrastructure and Sustainable Land Management

32. Usage of European Census Data for Sustainable Land Management – A German Case Study Ulrike Klein and Hartmut Müller 5 Some Use Cases

33. Usage of European Census Data for Sustainable Land Management – A German Case Study Ulrike Klein and Hartmut Müller Use Case 1 Kindergarten Children under 6 years Available Places in Kindergarten Political Idea: Increasing female employment through better child care Spatial Questions: Where do children under the age of 6 live? Which kindergartens are in the area? How many places do they have? How many children are already there? Which is the next kindergarten for each building block? Are there enough places available? If not: Are alternatives available?

34. Usage of European Census Data for Sustainable Land Management – A German Case Study Ulrike Klein and Hartmut Müller Use Case 2 Sewage System Number of Inhabitants Condition of Sewage System Problem: If less people use the sewage system problems with hygienic standards and damages of the sewage system occur (e.g. less money for necessairy repair, contamination with medical residues, in worst case: contamination of groundwater ) Spatial Questions: How many people of which age live in each building block? How is the condition of the sewage system? Which part should be repaired next?

35. Usage of European Census Data for Sustainable Land Management – A German Case Study Ulrike Klein and Hartmut Müller Use Case 3 Energy Energy Efficiency Heating Requirements Political Idea: Calculate heating requirements Spatial Questions: How old are the buildings in each building block? Which energy efficiency do they have? How much energy is needed for heating?

36. Usage of European Census Data for Sustainable Land Management – A German Case Study Ulrike Klein and Hartmut Müller Use Case 4 Public Transportation Catchment Areas Number of Inhabitants Question: Is the infrastructure (like schools, doctors, workplaces) easy accessible through public transport systems? Spatial Questions: Where are bus or train stops? How many people live in the catchment area of each station? How old are they? Do they need special equipment?

38. Usage of European Census Data for Sustainable Land Management – A German Case Study Ulrike Klein and Hartmut Müller Census data, a highly valuable source for sustainable land management The spatial dimension of census data – in practice often a hidden treasure Unearthing the treasure - needs integration of various data formats and representations - is often a challenging and time intensive process - helps to generate new knowledge on spatial patterns and relations of census data
