The GEOSTAT_Grid_POP_2006_1K European population grid dataset for the reference year 2006 integrates data from national grid initiatives and the European disaggregated dataset produced by the Austrian Institute for Technology (AIT) into an integrated single population grid dataset.
The folder GEOSTAT_Grid_POP_2006_1K.7z contains the following files: - the actual population data in csv format, GEOSTAT_Grid_POP_2006_1K.csv, - an empty grid net, Grid_ETRS89_LAEA_1K_ref_GEOSTAT_POP_2006.shp, as a spatial reference grid to the gride cell codes used in GEOSTAT_Grid_POP_2006_1K.csv. The grid was created according to the INSPIRE data specifications for European grids. The grid net Grid_ETRS89_LAEA_1K_ref_GEOSTAT_2006.shp only contains cells that are inhabited. Area not covered by grid cells is therefore not inhabited by residential population for the reference year 2006. - An INSPIRE metadata file in ISO19139 encoding, MD_GEOSTAT_Grid_POP_2006_1K.xml. The metadata file provides mainly information on the production process of the individual national datasets that were integrated into this European grid - A file describing conditions for access and use of the population data, GEOSTAT_Grid_POP_2006_1K_Usage-and-License-Conditions.txt.
