Event details

The second event in our new Public Lecture Series, which focuses on population and migration issues, takes place on Tuesday 20 November and will examine the uncertainty and complexity of migration.

An increasingly interconnected world

Human migration is very complex. In our increasingly interconnected world, people around the globe choose to move for many different reasons. Some do so in order to escape poverty, war or persecution; others seek new opportunities through jobs, study, family reunion, or try to improve their quality of life.

Migration can impact economies and societies, trigger policy responses, and cause political debate. Once it begins, migration often leads to further mobility, and attempts to restrain it can often result in unintended consequences.

Unpredictable and uncertain

Due to the inherent complexity of international migration, it is also one of the most unpredictable and uncertain population processes and a fascinating area of study. According to the UN , roughly 3.4 per cent of the global population is foreign-born. But migration measures, even in developed countries, are subject to a very high degree of uncertainty; there are different definitions of a long-term migrant and different policy structures which make producing comparable data a challenge.

Patterns of migration

Administrative systems also impact the accuracy and completeness of some of the data we rely on. Patterns of migration can also quickly alter as a result of changing political and economic circumstances, meaning that migration can be a very difficult process to analyse, predict, and control.
In this session, our experts will explore some of the major challenges surrounding migration, including decision-making and accurate methods of measurement and prediction. We will also look at the different ways migration can impact policy, which takes the complexity and uncertainty of the process for what it is: neither something to ignore nor fight against, but rather an inherent feature of mobility that needs to be acknowledged and managed.

In Conversation

This event is the first in our Public Lecture Series to take the form of an 'In Conversation' session, with Jakub Bijak, Professor of Statistical Demography, and Jon Simmons, of the Home Office Analysis and Insight Directorate, examining the complexities of migration in a discussion facilitated by journalist and University of Southampton alumnus Jason Cowley.
