Outline

3. • A system of four base registers
identifying frame populations
interconnected by linking codes.
• Continuously updated from
administrative sources and
integrated by statistical surveys.
• Connected to satellite registers
for targeted process

4. The statistical register of territorial entities allows for more detailed,
frequent, updated, linked and interoperable geographical data.
Two main aims:
1. support the production process of official statistics (registers,
censuses, surveys) w.r.t. the geographical dimension through the
localisation in the territory (and its continuous update) of the
statistical units;
2. produce statistics to describe and characterise the territory.

RSBL - Statistical Base Register of Territorial and Geographical Entities

5. o The register ensures:
o the coherence of territorial codes in all registers;
o the maintenance of the nomenclatures and geographies (the dynamics of
changes of some of these units is very high and uneven on the territory);
o the revision of the codification rules (to guarantee the consistency and
sustainability of the process to date back entities over time in the long term);
o the enrichment of the territorial units with typologies, classifications,
structural characteristics etc.;
o the record of statistics on such units.

RSBL - Statistical Base Register of Territorial and Geographical Entities

6. It is part of the Integrated System
of Registers and it is in itself a
multidimensional register
integrating five components.
It represents an innovative way to
integrate the most relevant
components of
territorial/geographical data.

8. We are currently building the prototype. Policy drives the choice of first inclusion:
o Sub-municipal areas of large LAUs (quartiers): policy against degrade in peripheries;
o Internal zones Project-Areas: built to contrast depopulation in specific peripheral
territories characterised by remoteness.
o Italian Functional Urban Areas: Eurostat/OECD functional areas based on the
gravitational model applied to the cities. The FUA comprises the city and its
commuting zone.
o Labour Market Areas: functional areas based on the concept of self-containment of
the commuting flows. LMA are present in all territories .

10. LMAs are areas where the bulk of the workforce
lives and works (self-containment of flows)
1. Common methodology (Eurostat Task Force
based on the report by Coombes et al. 2013)
2. Open source tool: package
LabourMarketAreas that covers the whole
production process of the LMAs (2016
Eurostat Grant) - We have just released
version 3.2.2 (maintenance)
3. Shared guidelines (Eurostat grant)
4. Replicability: many MSs have developed this

LMAs implementation: a EU wide approach

11. The EU experiences and the modernisation of statistical systems imply the inclusion of
different dimensions in the implementation process: multisource.
o Commuting data from multiple countries: Borders do not stop commuters.
Cross-border LMAs: NL-DE-BE, now CH;
o Commuting data from multiple sources: administrative and sample data;
o Statistics from integrated data: data stemming from different statistical registers.

Multisource: different types of data
• Census 2011 = Complete enumeration
• Census 2021 = Administrative and survey data: multisource data
• Commuting data stemming from surveys: precise definition of commuters but:
commuters refer to different periods in time, possibly different sub-
populations, probably different administrative units, sample.
• Commuting data from administrative source: possibly no side information on the
type of work, the commuting, if any, and its frequency;
are all possible types of works represented? etc.
• Sophisticated integration/estimation methods need to be developed.

14. o 2018 Eurostat Task Force on «Establishment of European sets of LMAs»
o Comparability of LMAs at EU Level
Aim:
Find a flexible method to allow for comparable functional areas
Requirement:
maintain the national setting for national needs

LMAs recent developments: comparability and rural typology

15. • Create EU Functional Areas using as building blocks the national LMAs
• These new Functional Areas are built using the same parameters for the whole
of Europe and the same tool, the package LabourMarketAreas

LMAs recent developments: comparability

16. o «LMAonLMA» concept allows to
harmonise the geographies built in
different MSs.
o In Italy:
o LAUs (municipalities) -> 8092
o LMAs -> 611
o LMAonLMA -> 213

Different geographies – different uses
• Eurostat Task Force has proposed a definition for rural functional area (degurba)
based on commuting inside the area. Experiments are under way.

18. o The modernisation of statistical systems creates new infrastructures that greatly
improves the availability of integrated georeferenced data;
o This new availability facilitates the production of statistics on different geographies;
o Comparable functional geographies that cover the whole of the country are needed
to guide policy and planning in all territories;
o Experiences carried out on Labour Market Areas in Italy and other EU countries
show that the approach developed within Eurostat grants and Task Forces can
represent a viable solution in this direction.
