• 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

• 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.”
