Explanation of the Excel and Access database

The Access database is made up out of three tables:
Table 1 - Population 
In this table the unit of research is the total number of people for a particular cross section in time, in a particular area. This population is characterised by several attributes, e.g. gender, age, marital status, economic branch, occupation, nationality, ethnicity, religion, social group. The data are entered as they are found in the sources, the sources are mentioned in table 2. To the data found in sources an interpretation is added, i.e. labour relation. The typology of this feature is given in table 3.
Table 2 - Source
All sources used to build the database are entered in a separate table that corresponds with the main population table. In this table, all sources used to build table 1 are described and encoded. Codes refer to paper copies of essential parts of the sources.
Table 3 - Typology V (of Labour Relations)
This table gives an overview of all prevailing labour relations, as developed by the research group. The several types are determined by the ownership of labour power; - instruments; output and means of subsistence. 
In the Excel files these tables correspond to the tabs 'Data entry' (=Table 1), 'Sources' (=Table 2) and 'Labour relations used' (=3).
