The report was prepared under the responsibility of the United Nations Economic Commission for Europe in the framework the project “Strengthening national capacities to deal with international migration: maximizing development benefits and minimizing negative impacts”. The project involved all five regional commissions of the United Nations and was financed from the United Nations Development Account.

Responding to the demand for evidence-based policies, the report provides a review of sources and quality of statistics on international migration in selected countries of the Commonwealth of Independent States (CIS): Azerbaijan, Kazakhstan, Kyrgyzstan, the Russian Federation and Tajikistan.

The report gives a general overview of the existing or potentially available systems of migration data collection and of data quality assessment where data are available. It builds on the review of the systems of migration data collection and production in CIS countries, which the United Nations Economic Commission in Europe (UNECE) conducted in 2007.
