This shows that immigrant workers are likely to be in the mid-20s and 30s. It is this age group where workers are most flexible and willing to travel to find work. As they near retirement age, immigrant workers are more likely to return to the country of their origin. This age composition has implications for net contribution to tax revenues.

Impact of Net Immigration on UK Economy

1. Increase in Labour Force

Migrants are more likely to be of working age. The majority of migrants come for work or study (students) They may bring dependents, but generally net immigration leads to an increase in the labour force, a decline in the dependency ratio and increases the potential output capacity of the economy.

2. Increase in aggregate demand and Real GDP

Net inflows of people also lead to an increase in aggregate demand. Migrants will increase the total spending within the economy. As well as increasing the supply of labour, there will be an increase in the demand for labour – relating to the increased spending within the economy. Ceteris paribus, net migration should lead to an increase in real GDP. The impact on real GDP per capita is less certain.
