STREAM was developed for fundamental research on long-term processes in the County of Flanders and the Duchy of Brabant (1500-1815). This area today largely corresponds to the provinces of Antwerp, East and West Flanders, Flemish and Walloon Brabant, including the Brussels region. To meet diverse information needs, key quantitative data for each locality was traced in archival documents, entered, harmonized, and made exploitable for research. The data comes from a wide range of sources containing quantifiable information. They cover the following details and sources:
| Territorial division | Administrative censuses and maps (including the Ferraris map, see below), fiscal transport tables |
| Demography | Static sources: censuses, population lists (status animarum), communicant lists, hearth counts, fiscal surveys |
| Dynamic sources: baptisms, marriages, and burials in parish registers per year | |
| Migration | Citizen admission books, passport registers |
| Social | Lists of relief recipients; surveys on poor relief |
| Labour and occupational structures | Occupational censuses |
| Agriculture | Productivity (harvest counts), land use (land books, hundredth- and twentieth-penny taxes), livestock (cattle counts), and crops (grain counts) |
| Prices and wages |
STREAM also includes a Geographic Information System developed from the Ferraris map (1771-1777) to conduct spatial research on territorial organization and transport infrastructure.
