Population density grid, 2011, Population distribution - Dataset
This dataset contains the number of persons at their usual place of residence (total, by sex, by age: 0-14, 15-64, 65+) per km² for the reference year 2011 on the date of the Census: 1st of February. The data are georeferenced to the INSPIRE Grid_ETRS89-LAEA_1K. The actual data are contained in the file BG_Grid_POP_1K_2011.csv. The production process combines aggregation and disaggregation approaches, depending on the grid cell, in order to distribute all the population from the Census 2011 dataset. This hybrid dataset is a product of the GEOSTAT 1B project and supported by the European Commission and the European Forum for Geography and Statistics (www.efgs.info). The BG_Grid_POP_1K_2011 has the following attributes: GRD_ID (according to INSPIRE); METHD_CL per grid cell (A = aggregated, D= disaggregated, M= mixed); DATA_SRC= BG (ISO 3166 alpha-2 for Bulgaria), TOT_P = total residential population; TOT_F = total residential female population; TOT_M = total residential male population; T_00_14 = total residential population of age 0-14 years; T_15_64 = total residential population of age 15-64 years; T_65_ = total residential population of age 65+ years; LAU1= LAU1 national code is determined by surface area. Any grid at the border between two or more municipalities is given the code of the municipality with the larger surface area on the grid; YEAR= reference year for population statistics.

BG Census 2011 population as of 01.02.2011: 7364570. Total population distributed in grid cells: 7364570. Population allocated based on residential address position, using address points reprojected to ETRS89-LAEA (57.3% of total population). Population without coordinates allocated using statistical density model (42.7% of total). The population density grid of Bulgaria 2011 is produced with a combination of “bottom-up” (aggregation) and “top-down” (disaggregation) approaches. The aggregation approach is applied mainly in bigger settlements where more than half of the population is concentrated and where the share of geocoded address data is very high. The disaggregation (dasymetric binary method) is applied where the data about exact location of the population is not geocoded, mainly rural areas with small settlements without officially adopted cadastral plans. Hybrid approach source data and methodology.(Population): Census 2011 with multilevel address locator data (NSI); (Address location): Location points (Geodesy, Cartography and Cadastre Agency), Location boundaries - LAU2 and lower level (NSI), Input data (Ancilary for disaggregation): Land cover/land use layer of populated and build-up areas (Ministry of Agriculture and Food), Urban Atlas (European Environment Agency); Target reference dataset: Grid_ETRS89_LAEA_1K (Eurostat). Methododlogy:1) Aggregation from census data by address location points to 1 km grid. 2) Population without address-coordinates summarized by location areas 3) Definition of potential residential areas from ancillary layers. 4) Intersection of ancillary layers and location areas 5) Applying statistical density model. 6) Aggregation of disaggregated population to 1km grid. 7) Sumarize results from aggregation and disaggregation to 1km grid.
