  1. International migration data sharing: What can be done in the UNECE region? Paolo Valente, UNECE UNECE-Eurostat Work Session on Migration Statistics Geneva, 14-16 April 2010

  2. Background – UNECE (cont.) 2006: Data exchange exercise for preparation of Guidelines (19 countries in 4 clusters) 2007: UNECE Study on data exchange in 11 CIS countries 2009: Guidelines on exchanging data to improve emigration statistics, suggesting: a) Set of standard tables on stocks and flows for bilateral exchanges among countries b) Setting up clearing house maintained by an Intl. Org. to facilitate sharing of data among countries

  3. Background – UNECE (cont.) 2010: UN Development Account Project on migration – Objectives include: • Improving migration data quality • Promoting exchange and dissemination of information on migration  Feb. 2010: Workshop in Bishkek (CIS countries) • Agreed set of 9 tables on basic migration data to be transmitted to UNECE by participating countries

  4. Other initiatives • Other data collection, sharing, dissemination initiatives in the UNECE region: • Joint migration questionnaire (Eurostat, UNSD, UNECE…) (flows) currently being revised • Eurostat data collection (EU regulation, incl. candidates + EFTA) • UNSD Questionnaire on flows (under revision) + Quest. on stocks (census data) • UN Global Migration Database (UN Pop. Div.) (stocks) based on UNSD quest. & other sources • OECD-World Bank collection on characteristics of immigrants living in OECD countries (stocks) • IOM/UN-ESCAP planned data collection in ASIA • …

  5. Priority: Avoid duplication!  Launch a new initiative only if: • It’s not duplicating other existing activities • There is clear added value for final users • Countries are willing to participate • Mechanism can be set up and maintained with resources available in UNECE and NSIs • Alternative: use resources to support and contribute to existing initiative(s)

  6. Key decisions to be taken 1. Objective of new initiative: • Data sharing AND dissemination? • Data sharing only? (dissemination through other existing platforms)

  7. Key decisions to be taken 2. Which countries should participate? • Bilateral exchanges (Guidelines)? • Sub-regional level (ex. CIS) only? • Regional (UNECE) level? • Support to existing global initiative? (i.e. support revision of Joint migration questionnaire)

  8. Key decisions to be taken 3. What data to be exchanged? • Limited set of tables on stocks and flows? (Guidelines, Bishkek workshop?) • Focus only on stock data from 2010 round censuses?

  9. Technological solutions • To be discussed in detail depending on the “key decisions” still to be taken • UNECE has limited resources to manage the process once it will be set up. Therefore: • Preference for models based on automatic data transmission, or data “pushed” by countries • No heavy data processing possible in UNECE • UNECE has expertise on IT systems for data exchange and dissemination, and can provide technical support (including Russian speaking IT expert)

  10. Data exchange formats Solution 1 (hi-tech) based on: • SDMX (Statistical Data and Metadata Exchange) standard • Software for Census hub developed by Eurostat Requirements: • Knowledge of SDMX format • Relational database (i.e. SQL, Oracle, Access) • Stable IT infrastructure, good access to Internet

  11. Data exchange formats (cont.) Solution 2 (low-tech) based on: • CSV files produced with Excel • Transmission by email or UNECE downloads from NSI website Requirements: • Minimal: Excel and email Each country could choose between solution 1 or 2 They could be used in parallel…

  12. SDMX Country 1 UNECE SDMX Country 2 CSV Country 3 Data exchange formats
