Monitoring and benchmarking the European territory The M4D contribution: Time-series, Urban Data and Case Studies 4-5 December 2013 Vilnius, Lithuania Claude GRASLAND on behalf of M4D 1
Data, data, data… ESPON Seminar in Vilnius, Dec. 2013 ESPON Seminar in Lillehammer, Dec. 2003 … • Need for data at the beginning of TPGs projects. • Need for the most recent data. • Need for measuring dynamics (managing NUTS change) 6
The M4D answer (2011-2013) M4D Core Indicators • Total population: 1990 – 2011, NUTS 0-1-2-3 • Age structure (5 years): 2000 – 2009, NUTS 0-1-2 • Births / deaths: 2000-2010, NUTS 0-1-2-3 • GDP (euros/pps): 1999-2008, NUTS 0-1-2-3 • Active population: 1999-2008, NUTS 0-1-2 • Unemployed/employed population: 1999-2008, NUTS 0-1-2 • ESPON Area + Candidate Countries • No missing values But.. 7
The M4D answer (2011-2013) • All Eurostat values have been kept, NUTS 2006 version • Potential problems of statistical discontinuities. • Missing values have been estimated within the ESTI framework (time, space, thematic, source dimensions) • Short time-series to statistically ensure the quality of the estimation, no margin of error. • A manual process • Several months of work, errors may remain, difficult to update. A first useful attempt A non-sustainable solution 8
The M4D answer (2011-2013) Total population 1990-2011 dataset Need temporal smoothing? New censuses heterogenous methods for gathering data 9

The M4D answer in 2014 • We can estimate missing values in the official series data to create the best official time series Green cells have complete official data; red cells require estimation Before estimation After estimation 11
Next steps for the M4D time-series… smoothing discontinuities • The official series are not always smooth – here the year-on-year growth rates reveal unexpectedly rapid changes between 2002/3 and 2003/4 in some of the series. • If there is no apparent reason for these changes we will locally smooth the outliers to give the best homogenised series. 12
What could be strategic for time-series creation? • Official data and smoothed data Need for official data Need for smoothed data European Commission website ESPON ET 2050 ESPON DEMIFER • Benchmark with policy objectives. • One-shot results (situation in …?) • Need temporal smoothed input data to propose relevant forecasts. 13
What could be strategic for time-series creation? M4D Draft Final Report (June 2014) • Feedback on 7 years of database project. • Recommandations for 2014-2020. 14
Several European urban databases Already integrated in the Espon DB Waiting for the final version
Several European urban databases • 4 different urban DB have been expertized by ESPON M4D • 2 morphological delineations (continuous built-up areas) • 2 functional urban areas • Among them, 3 have already been integrated into the ESPON DB portal • The last one, the Harmonized LUZ (Urban Audit 2012) should be uploaded when available
Two complementary urban databases UMZ – 4304 cities Harmonized LUZ – 695 cities provisional version (Dec. 2012)
The small & medium sized cities: another major issue for European planning and urban policies 12 LUZ 55 UMZ Advantage of UMZ DB: small & medium cities EXIST
Two complementary urban databases • Importance of harmonized LUZ • For the first time, an official harmonized DB • Integrate large perimeters that functionally depend on core cities • Should be related to various socio/economic/demographic indicators (Urban Audit) • Importance of UMZ • Small&medium city sized cities are captured • Major policy stakes • Future urban objectives in structural funds • Allow a better knowledge of territorial dynamics
Two different ways for attributing indicators into urban objects LAU2 (SIRE DB) Grid data (GeoStat 2006 / JRC / Corin Land Cover) Urban Databases Problem of availability of time series Few indicators at the moment
Population urban objects to LAU2 data need a dictionary Elaborating the UMZ-LAU2 dictionary: a very complex task UMZ – LAU2 dictionary Available in the ESPON DB portal
Urban OLAP Cube: a method to create grid indicator from administrative levels (NUTS2/3) GEOSTAT Pop. Grid 2006 Urban Objects OLAP Database Measures 100 x 100 m Grid UMZ LUZ ESPON URBAN OLAP Cube MUA FUA ! Area (1Km²) Data Source • The data source used to populate the urban objects depends on their definitions: • Morphological objects can be populated by Local or grid data • Functional objects can be populated by these one and NUTS data disaggregated LAU 2 NUTS LAU 2 End Users Urban Atlas 10 m Urban Atlas 10 m
Two different ways for attributing indicators into urban objects • Urban objects are defined by geometric attributes (delineations) and thematic attributes • It is essential to populate urban DB with indicators (social, economic, demographic, environmental…) • Two different ways: using indicators available at LAU2 level OR using grids • LAU2 information • A fundamental pre-requisite: creating links between urban objects and local units (dictionary) • A major issue: robustness and completeness of SIRE DB • Grids information • Easy to populate urban database by OLAP cube • But risk of statistical illusion (e.g. GDP Nuts 3 -> GRID - >LUZ)
Enriching urban databases (SIRE DB UMZ) Age structure – European level
Enriching urban databases (SIRE DB UMZ) Age structure – Regional level
Results (SIRE DB UMZ): Age structure • An example of thematic valorisation of harmonized urban DB: a typology of age structure by city • At the European scale, three main types of regions • Ageing ones (Germany, Austria, northern Italy & Spain) • Intermediate (UK, France, Belgium, Netherlands, northern Europe) • Young ones (Central & Eastern Europe, southern Italy & Spain, Greece, Ireland) • When typologing at regional scale (central Europe), city size effects appear along side regional differenciations (West-East) • Large cities oldest • Small&medium youngest
Introduction • ESPON TPGs can deliver two types of datasets: • Case Study datasets • Key indicator datasets 29
Introduction • ESPON TPGs can deliver two types of datasets: • Key indicator datasets • Case Study datasets • Cover the entire ESPON Space (EU28+4+CC) • Respect the ESPON metadata and data template (INSPIRE) • Rely on NUTS or Urban nomenclatures 30
Introduction • ESPON TPGs can deliver two types of datasets: • Case Study datasets • Key indicator datasets • Does not necessary cover the entire ESPON Space • May be data at local scale • May be data to compare different regions in the world (Barcelona vs Mexico) • Cover the entire ESPON Space (EU28+4+CC) • Respect the ESPON metadata and data template (INSPIRE) • Rely on NUTS or Urban nomenclatures 31
