2. Re-Urbanization in European cities:
• empirical survey of 15 German cities: • development like a ´cascade‘: • immigrants (also from other cities in Germany)
moved to the inner cities (gateway-function) • immigrants are young people from 18-30 years • this group has risen about 48% in the inner cities
from 2002-2008 (rejuvenation) • long-time residents moved to the outer districts • the outer districts lost population to the suburbs

2. Re-Urbanization in Leipzig, Bologna, León, Ljubljana:
Drivers of Re-Urba-nization as a share of total population in case study areas (households who moved into the case study areas within the last 5 years)
PROF. DR. GUIDO SPARS

Economic drivers of the Re-Urbanization • economic structural change: rising of the knowledge-
intensive economy • importance of tacit knowledge (face-to-face) • erosion of normal working and living conditions • more and more globalised and flexibilized society • but: need of „homebase“, need of relocalization of
people and functions (glocalisation!) • need of complex spaces of options and spill over effects
(social infrastructures, services, communication, information)
Cities become more important
PROF. DR. GUIDO SPARS
11
Qualitative aspects of Re-Urbanization • Re-Urbanization means also a qualitative change • proximity of working and living • urban milieu: atmosphere, inspiration, non-routine
production and consumption • big city development projects (housing, event culture,
retail, public spaces, gastronomy) • development of inner city mixed-use quarter • quality of public space, multifarious culture + leisure
time facilities, short ways, public transport etc. Soft factors become more important
PROF. DR. GUIDO SPARS
12
Target groups of Re-Urbanization: Reurbanites
• young urban professionals, creative class • education oriented people • best ager / silver ager (active livestyle with options and
short ways) • city oriented families • immigrants from all demographic groups
PROF. DR. GUIDO SPARS
13
Stability of the Re-Urbanization trend?
• the economic processes behind the Re-Urbanization are ongoing
• also immigration will be a ongoing phenomenon • certainly the trend of Suburbanisation is still going on • it will not be possible to satisfy all people who want to
live in the city! • Scarcity of land and space • High prices, gentrification
good planning /governance: managing the parallel and complementary process of urban sprawl and Re-Urbanization
