This polygon shapefile represents basic population characteristics for municipalities in El Salvador, collected as part of the Censos Nacionales 2007 by the Dirección General de Estadística y Censos. Indicators in this layer include sex, age, and birth date (by day of month, month and year). This layer was derived from a geodatabase (see the related data file) and was documented and restructured by East View Cartographic, Inc. The census data is provided at the municipal administrative level (ADM2) and includes 273 polygons with 1162 attribute variables, split into 6 layers. Attribute descriptions retain original language names and unique identifier codes. All variable names were translated from Spanish. Field name prefixes, originally written with coded titles, were renamed to create unique names (e.g. Original variable of “P02_Hombre” was updated to D001 and given the alias “Sex: Man[P02_Hombre]”, the letter D was given as it relates to the Demographic theme table. D = Demographic, E = Economic, H = Housing, M = Migration, S = Social and T = Transportation). All variables from the original data were reviewed for completeness and organized into their relevant themes of Demographic, Economic, Housing, Migration, Social and Transportation. In the attribute tables, all geographic names and codes are represented as text fields and census data are represented as doubles or long integers. Automated tools were run to apply aliases in the format “English translation field description[Native language field description]”. Vector data was analyzed for accuracy and compared with national boundaries. This layer is part of a partnership project with East View Cartographic and IPUMS International, titled the Global Census Archive.
