Title: Marge Fauvelle and Ayima Okeeva (UNECE)
1Main results of the UNECE Questionnaire on
International Migration Statistics and
difficult-to-measure migrant groups
- Marge Fauvelle and Ayima Okeeva (UNECE)
2Objectives of the Questionnaire
- To review how national statistical offices (NSOs)
define migrant stocks and migration flows - To build a crosswalk between definitions and
sources used by different countries - To obtain a preliminary glimpse of data quality
from the various sources and for the different
population groups -
- To collect information on practices and
methodologies used to define and estimate
difficult to measure international migrant
groups.
3Structure of the Questionnaire
1. Entire Populations 1a. Stocks of International Migrants Questions for 9 types of data source relating to UNECE definitions of population groups
1. Entire Populations 1b. Flows of International Migrants Immigrants - Data sources duration of stay coverage (legal status) data adjustments/revisions/corrections. Emigrants - Data sources duration of stay coverage (legal status) data adjustments/revisions/corrections Both - Population balancing equation

15Conclusions (i)(Part 1 of questionnaire)
- Censuses represent the commonest data source for
migration statistics - Foreign-born and Foreigners are the
definitions most commonly used to identify stocks
of immigrants - But not all countries adhere precisely to the UN
definitions (32/45) and (33/43) respectively
(Future Census). - Household Surveys also have some potential 17/26
countries can adhere to the UN definition for
Foreign-born. - Data on Foreigners are also obtainable in 23
countries from population registers and records
of residence/stay permits. - Length of stay is a determinant for about
two-fifths of countries - Censuses, population registers, surveys and
resident permit records represent a source of
information for certain, but not all hard to
measure groups. - 20 countries use population registers to measure
immigrant population flows - 14 countries are revising or adjusting their
migration data in some way
16Methodologies for estimating Difficult to
Measure International Migrant Groups
17Objectives
- To explore the relevance of difficult to
measure international migrant groups - To identify the group(s) for which the provision
of a statistical count/estimate represents an
issue - To find out whether estimates of difficult to
measure international migrant group(s) are
provided within the framework of official
statistics or by other data providers - To collect information on the methodology
utilized for the estimation.
18Groups considered
- Short-term migrants
- Irregular/undocumented migrants
- Refugees/forced migrants
- Asylum seekers
- Transit migrants
- Circular migrants
- Trafficked migrants
- Minors
19MAIN RESULTS
20Limitations
- Comparability of data
- - Little (or no) access to data
- Definitions
- Particularity of these migrant groups
- Heterogeneous sources
21Relevance of "Difficult to Measure" Migrant
Groups in UNECE Member States
22Challenges in Provision of Statistical Estimates
on Difficult to MeasureMigrant Groups
23Provision of Statistical Estimatesby National
Statistical Offices
24To estimate Difficult to Measure migrant groups
various sources are used by
- NSOs
- Other government agency or local authority
- Research institutes, universities and NGOs
All reported using various sources
25Conclusions (ii)(Difficult to Measure)
- Demonstrated interest of some States
- Existing good country practices
- Administrative sources have some potential
- Existing possibilities to collect and produce
migration statistics on a national level - Willingness of international organizations to
assist and support initiatives on collection and
production of data
26Conclusions (iii)(Overall)
- Some progress has been made in terms of mapping
data availability in UNECE region - Mapping exercise includes a number of
perspectives, stocks and flows immigrant and
emigrant groups length of stay hard to measure
groups and methodological considerations
(coverage/inclusion) - Response to the questionnaire has been excellent,
but parts of some questionnaires incomplete for
institutional reasons. - Some useful metadata provided
- Some inconsistencies noticed in responses (i.e.
minors) - The value of Household surveys for migration
statistics is better defined - The importance of forthcoming Censuses as a data
source migration statistics is overwhelming
