Compare territorial aggregates
Link code, classification and membership to table dimensions before joining or summing.
Documents to open in this workflow
This order suggests a starting point; revisit a step if identifiers, dates or versions disagree. Access and reuse terms depend on each service.
UNSD — M49
Identify UN statistical countries or areas and groupings using their M49 codes.
What to record
M49 code as text, label, grouping, reference date, dataset classification and aggregate coverage.
Source-specific check
Keep leading zeros. Two identically named aggregates may contain different units.
Open source portalEurostat · Data Browser
Compare European statistical series using dataset codes, dimensions, units and metadata.
What to record
Dataset code, selected dimensions, unit, period, source, extraction date and method note.
Source-specific check
Revisions may change figures; compare extracts using the same scope and method.
Open source portalUN System Data Commons
Explore the common United Nations system data and statistics gateway; identify the producer of each indicator.
What to record
Indicator, producing agency, country, period, unit, version and table URL.
Source-specific check
Trace the original source; inclusion in a shared portal does not automatically harmonise methods.
Open source portal
Matching condition
Link code, classification, members and period; do not join aggregates by name alone.
If results disagree
Changed membership needs constant scope or an explained break, not a label correction.
Output to produce
Crosswalk of units and vintages.
Separate documentary evidence, demonstrated links between documents and remaining inference. State the owner and review trigger.

Frequently asked questions
What link should be checked before matching results?
Link code, classification, members and period; do not join aggregates by name alone.
What if sources appear to contradict each other?
Changed membership needs constant scope or an explained break, not a label correction.
Do the listed portals provide independent confirmation?
Not necessarily. Identify the producer and underlying document. Two interfaces distributing one item can check transcription but do not establish a fact independently twice.
