• Each year, a new Structural population frame is built
• All active enterprises are included
• All enterprises with activity cessation in reference period
are included
• All Institutional sectors are included
• The sampling frame will be obtained from this Structural
population frame

• Ministry of Justice - National Registry of Legal Persons
• Ministry of Finance - Corporate Tax- Income Tax
• SICAE system (a partnership information system about legal units
NACE code, where Statistics Portugal is one of the three partners, the
others are Tax Authority and Institute of Registration and Notary Affairs)

• Each variable of the BR is linked to different information
sources, ranked by degree of importance
• For each variable a cross-check is made by comparing the
information provided by the source with the one contained in
the BR
• Concerning the economic variables a growth rate is
calculated and an acceptable range is established. Those
that fall out of this range are subject to further analysis

• In 2011, Statistics Portugal constructed a national geographical database of
all the georeferenced buildings from the 2011 Census
• This geographical dataset has been used to reference census data at point
level and to support the creation of a National Dwellings Register (FNA)
• FNA is updated by data available in different sources: (1) surveys conducted by
Statistics Portugal: (2) administrative sources

• Statistics Portugal strategy to improve the efficiency statistical
process
• Grant: “Merging statistics and geospatial information in
member states”
GOAL
• Implement a spatially enabled and quality-controlled point
based infrastructure for the production and delivery of BR
statistics at all relevant geographic breakdown levels by
means of data integration
Action
The current action is integrated into:
» 16
The address is the key element to directly or indirectly match the
records with the existing BGE
following a step-by-step approach based on locators capable of
sequentially pinpoint the BR records
A different mix of those locators has been used for the cases
processed
BR Geo processing
MORADA_CP7 Complete address composed by type of road, name, number, 7 digit postal code
BSA_CP7_DTA BSA_CP7_ESQ
Used over the BSA in order to overcome discrepancies in the address
MORADA_LOC_CP4 Uses the locality name and the 4 digit postal code
CP7 Based on the 7 digit postal code, which is a linear structure used to code each block façade composed by the CP4 and 3 additional digits
CP4 Based on the 4 digit postal code, which is a polygonal structure used to code each postal distribution area

“The alignment is the mapping between source and target
schemas. It defines relations between source and target
entities (types or properties). Based on the defined
relations a transformation is derived.”
