Introduction: aim and limits of this draft presentation. 2

Long historical trends: –Institutional framework and evolution. –Intellectual background. –The post-1978 administrative framework: central, regional and local institutions. 3 Ministerio de la Vivienda (2006) “Atlas de Áreas Urbanas Españolas” Tomás López (1773) Mapa de la Provincia de Madrid

The classical descriptive studies (provinces). 4 Instituto Geográfico Nacional “Atlas Nacional de España ”, Información Demográfica: Movimiento Natural de la Población”

The classical descriptive studies (municipalities). 5 Instituto Geográfico Nacional “Atlas Nacional de España ”, Información Demográfica: Población por municipio 1981

The sprawl of geographical information and studies (I): tracking the urban and metropolitan areas in Spain. 6 Ministerio de la Vivienda (2006) “Atlas de Áreas Urbanas Españolas”

The sprawl of geographical information and studies (II): building models for driven the small numbers within health / mortality studies. 7 Instituto de Salud Carlos III (2007) “Atlas municipal de mortalidad por cáncer ”

The sprawl of geographical information and studies (III): Industrial Local Units by detailed branch and by very small areas (urban morphological zones). 8 Instituto de Estadística de la Comunidad de Madrid (2007) “Atlas de la Industria”

The sprawl of geographical information and studies (IV): geocoding enterprises (jobs of Services Local Units). 9 Instituto de Estadística de la Comunidad de Madrid (2008) “Atlas de los Servicios de la Comunidad de Madrid”

The context and main projects of the National Statistical Institute: –Population Register (Padrón de Habitantes, from 1996). Straight collaboration with all municipalities of Spain. –Business Register (DIRCE, from 1999). Tax agencies, Social Security register and other sources. The backbone: statistical units and postal address. 10

GIS inside INE-Spain: an overview. –GIS as a tool for managing maps (following cadastral works) focused in the field-work approach. –Updating enumeration districts (Secciones censales). –Other projects: Urban Audit, Environment and agricultural statistics, following the Eurostat initiative. –Census

Census 2011 (I): –Partial matching with cadastral registers for available coordinates of buildings / postal addresses. central and provincial GIS tools for a more accurate matching. 12

Census 2011 (II): –Capturing / checking coordinates during census fieldwork. 13

Other projects: –Boundaries of small population units inside municipalities (small geographical/historical areas and morphological urban zones: small units, across municipalities of Spain (more detailed in the northern Spain due to the pattern of settlement). –Key yearly updated grid population statistics. –Grid business statistics. 14

a) Status of use of GIS in production and dissemination of statistics: -Small unit in charge of updating enumeration districts. Producing also conventional cartography and other maping needs. -Across the INE: some departmental expertise for producing thematic maps, for reports and news, mainly at provincial level. -No general mapping tool at INE-website, but currently under development. -Enumeration districts polygons available at website (not free). 15

b) Rules for handling confidentiality: -The confidentiality rules are developed at product unit level. -Long and broad experience with microdata files (considering the main tool is deleting the geographical detail of information). -Consolidated experience of population information at enumeration district level (1.000 to people) and for municipalities with low population. 16

c) Software in use: -ESRI products. -Using SAS-maps tools for thematic maps in some contexts of workflow. -SAS & ESRI joint collaboration for developing a web based tool for tables on demand, including spatial queries (datawarehouse and spatial services). 17

d) Organisation of GIS, number of staff etc: -Team for updating statistical units and general works: head and 5 people. -IT System Maintenance: 2 people partially involved. -Design and coordination geostatical issues: 2 person. -GIS expertise in other units: 1 person. -Census work related to coordinates capture and processing: under external contract. 18

e) Availability of basic geostatistical units (georeferenced; population, dwellings, buildings, enterprises, agricultural holdings and properties) -From Cadastral Agencies (3): buildings and blocks (polygons), streets (lines), postal numbers (points): in urban and rural parts of each municipality. Available cadastral plans for different floors / levels in each building. -From Map Agency (and Regional Map Agencies): municipality borders, topographical names, general geographical features, orto-images and satellite images. -Usually differences in the definition and codes with statistical units of NSI. 19

f) Policy with respect to licencing and pricing of statistics derived from use of GIS in production of statistics: -Currently: small price for enumeration districts files. -Future trends: free of charge. 20
