2. BACKGROUND: PROMOTION OF DATA SHARING Granular data exchange
Helps to have a more precise and complete vision to monitor the economy
Provides an opportunity to improve aggregated statistics
Helps to identify and solve inconsistencies among data collected by different players
Granular data is detailed data, or the lowest level that data can be in a target set.
As the data becomes more subdivided and specific, it is also considered more granular.
The advantage of granular data is that it can be molded in any way that the data scientist or analyst requires, just like granules of sand that conform to their container.
Granular data can be aggregated and disaggregated to meet the needs of different situations.

3. BACKGROUND: MEXICO’S INTERNATIONAL COOPERATION
Early 2017
Workshop on data exchange
Agreements on terminology, identification of barriers and possible solutions to these barriers
Inter-Agency Task Force on Statistics
Mexico has shared experiences on information granularity and exchange, aligned with DGI-1 and DGI-2 recommendations
Wiesbaden Group
Mexico participates exchanging experiences and performing joint work to develop, maintain and use business records
UNSC 48 Session Period
Mexico shared experiences adopting the SDMX classifier in the SNA and in the delivering and sharing of annual data with the OECD
March 2017
Bureau of the Conference of European Statisticians
Mexico participated in the working group of economic data exchange and sharing
April 2017

4. BACKGROUND: G-20 RECOMMENDATION
Recommendation II.20 of the Data Gap Initiative: Promotion of Data Sharing
The Inter-Agency Group on Economic and Financial Statistics (IAG) and G-20 economies to promote and encourage the exchange of data and metadata among and within G-20 economies, and with international agencies, to improve the quality (e.g., consistency) of data, and availability for policy use. The G-20 economies are also encouraged to increase the sharing and accessibility of granular data, if needed by revisiting existing confidentiality constraints.
The G20 Data Gaps initiative is a set of 20 recommendations on the enhancement of economics and financial statistics.
Its objective is to improve the availability and comparability of economic and financial data, as the turmoil that hit the markets - when the financial crisis broke out in highlighted the need of broader datasets for policy makers and supervisors to better assess the evolution of the economy, as well as the intervention required.
Recommendation #20 of the Data Gap Initiative (second face of the DGI) is to promote data sharing, granular data and identifying ways to overcome existing barriers as well as to strengthen the linkages and consistencies between datasets.

5. PRODUCTION OF MACROECONOMIC STATISTICS Macroeconomic Data Production
Requires inputs from multiple agencies
DGI-2 Objective
To implement the regular collection and dissemination of comparable, timely, integrated, high quality and standardized statistics for policy use
INEGI
In line with DGI-2 and other international groups, INEGI works domestically to achieve this goals
The highlights of the DGI-2 on Recommendation#20 Promotion of data exchange, are 7 recommendations to be adopted by national authorities and international organizations to improve the exchange and accessibility of granular data:
Promote the use of common statistical identifiers
Promote the exchange of experiences on statistical work with granular data and improve transparency.
Balance confidentiality and user needs.
Linking different datasets.
Provide data at international level.
Examination of the means to improve granular data exchange.
Collect data only once.

6. Numerical consistency
HARMONIZATION OF SNA
Concepts
Definitions
Basic classification
Numerical consistency
Exceptions
The SNA provides a conceptual and accounting framework for the coordination of economic statistics
The harmonization of the SNA and the related statistics boosts the analytical use of all of them
A coordinated work between the main actors: the NSO’s and Central Banks is crucial
In Mexico, INEGI has been working with other institutions to standardize methodologies in the framework of National Accounts, which are taken as a statistical source for the design of measurements in terms of stocks of financial assets.

7. WHAT HAS BEEN DONE WITH BANXICO?
The work with BANXICO began in May 2015, with the objective of standardize the SNA’s information of the SDMX tables presented to international organizations
INEGI
Financial Assets and Liabilities Balance Sheets (stocks)
Financial Account by Sector (transactions)
BANXICO
As part of its interinstitutional work INEGI has worked with Banxico on the adoption of the Balance of Payments Manual, already harmonized with the SNA2008, to improve the statistics used for national accounts.
The work has been done also with the CNSF and CONSAR in the homologation of statistics, in order to have harmonized methodologies that comply with international requirements, such as tables SDMX, Tables 7II and 7HH.

8. WHAT HAS BEEN DONE WITH BANXICO?
Objectives
Agreements
Adopt the Balance of Payments Manual, version 6 (MBP6), that is already harmonized with the SNA2008, to improve national accounts statistics.
Standardize BANXICO's monetary statistics and institutional sector balance sheets to fulfill requirements of international organizations such as the IMF and the OECD
Establishment of information exchange agreements regarding the coverage, version and sectorization of the information
Conceptual and methodological standardization of the statistics required to generate indicators on the SNA
With the Ministry of Finance, the works have been towards promoting among public institutions the adoption of guidelines established in the Government Accountancy, looking forward to align statistics according to the classifier issued by the National Council of Accounting Harmonization.
Nowadays, paperwork is been done before CNH and CRE, to generate an interinstitutional agreement as information supplier on all activities of the energy sector, with the aim of having a single window for the generation of various statistics in INEGI.

9. ACCOMPLISHMENTS ON DATA SHARING INEGI - BANXICO1 2 3 4 5
Classification of all economic sectors
Integration of INEG´s information of interest to BANXICO
Publication of historical statistics of assets and liabilities of intermediaries in the financial system
Generation of statistics of the International Investment Position with greater disaggregation
Fulfillment of the standard IMF disaggregation level for the Balance Payment´s statistics

10. FINAL REMARKS
Mexico has been very active in the interinstitutional information exchange both domestic and internationally looking forward to generate and disseminate granular statistics comparable at international level
The follow up to these initiatives and its results indicate the next steps to move forward in the data exchange field
Mexico, through INEGI, ratifies its commitment to the international statistical community to ensure that official statistical information is up to the society's demands
