What are the objectives of the EU’s external migration policy? With which countries are new migration agreements planned? How is the EU seeking to integrate non-European states into its violent migration control regime? And what impact will this have on people seeking protection, migrants, democracy and human rights, inside and outside the EU? A new project, ‘Outsourcing borders: Monitoring EU externalisation policy’ explores these questions. A bulletin to be published every two months by Statewatch and migration-control.info will analyse and compile the key documents produced and discussed by working groups in the Council of the EU.

The sampling method is significant to strengthen the representativeness of the sample and the generalizability of the research results. One of the non-probability sampling techniques is convenience sampling which is a way of selecting participants from the target population based on ease of access. This descriptive article aims to define convenient sampling, explain how to frame it, and finally its potential benefits and drawbacks. This sampling technique yields several inherent benefits, including being cost-effective, less time-consuming, simple operation, etc., and also possesses different drawbacks such as being subjected to sample biases, systematic errors, not being representative enough, and no generalizability of the research findings. The study concludes with some suggestions to improve the convenience sampling technique to ensure representativeness and remove uncertainty.
