Migration – a heterogeneous process. Many streams, many ‘causes’, many consequences. • ‘Pull’ and ‘push’ factors; inequalities. • Population pressures. • Force, political instability and persecution. • Environmental change. • Labour demand and recruitment • Opportunities for ‘betterment’. • Chains and bridgeheads, family and marriage. • Population ageing. • Subversion, terrorism and crime. • Policies in sending and receiving countries
Migration theory – rather a mess • Economists’ ‘equilibrium’ models – supply and demand for labour and capital. • Economic refinements – cost/benefit decisions; household investments; • World systems theory, Global cities; Segmented or ‘dual’ labour markets. • Networks, Cumulative causation. ‘transnational’ populations, non-economic movement. • Recent rediscovery of policy.
Some components of gross immigration inflows to Western Europe (blue is family; OECD 2003)
Long-term trends of migration to a ‘country of immigrants’
Consequences of migration • Demographic change. Growth and decline, age-structure effects, depopulation. • Salvation through migration? • Economic change – who benefits? • Replacement migration. • Ethnic change
Sweden 2004-2050: projected total population, millions, standard and zero-migration assumptions.
Ethnic replacement: • Continued migration from one population, into another with sub-replacement fertility, must eventually replace one with the other. • If incoming populations have higher fertility, the process will be accelerated. • Migration, not differential fertility, dominant effect.
Probabilistic projections of the UK – average outcome for major groups (%).
Comparison of results of European foreign-origin projections
Conclusions • Migration now a primary driver of population change in many low TFR countries. Not Far East, some CEE. • Patterns, sources, causes and consequences highly heterogeneous • Mixed economic consequences • Can moderate, not solve ageing • Possible ‘third demographic transition’
