"Although immigration from South Asia has added many highly numerate people to our labour force, immigration from the same region and Africa has added six times more people with low numeracy skills to the UK than those with high numeracy skills," Dr John Jerrim, the research"s author, said.
The UCL study also found that migrants to the UK are six times more likely to have never worked before than people leaving the country. Migrants are less likely to find any job, with unemployed female migrants almost double the rate of those born in the UK.
Britain has one of the highest migration rates in Europe and saw a 43-percent increase in numbers over the past year.
According to a review of the Migration Observatory, the size of the migrant population in the UK rose from about 3.8 million in 1993 to more than 7.9 million in 2013.
Such an upsurge in the size of the migrant population can be explained by the attractiveness of the UK's domestic welfare system and good living conditions.
Last November, UK Prime Minister David Cameron made a public statement, saying that immigrants will have to work for four years before they get any social benefits.
The measure is designed to make the country less attractive for newcomers and strengthen control over the migration process.
