A report from Lusa revealed the data that had been collected showed that as of March 2011 there were nearly 395,000 registered as living in Portugal, representing 3.7 percent of the total population of Portugal according to the 2011 Census.
Over the past 10 years the number of immigrants living in Portugal has grown by 167,781, however this increase is still not as dramatic as the increase in the previous decade which saw the number of foreign residents increasing by 120 percent.
According to the National Statistics Institute of Portugal (INE), the general profile of an immigrant in Portugal is that that of a woman, of Brazilian nationality, 34 years old, single, Catholic, with secondary education, residing in the Lisbon area and being employed as a cleaner.
The Census showed that more than half of all foreign residents in Portugal live in the cities of Lisbon and Sintra with many also living in Amadora, Cascais and Loures.
When it came to British residents the majority of those registered in Portugal were found to be living in the Algarve region while immigrants from the Ukraine, Romania and Moldova were found to be living in all areas of Portugal.
The data from INE found that the largest foreign community in Portugal came from Brazil with 109,787 people (around 28 percent of the total number of immigrants), followed by people from Cape Verde with 38,895 (10 percent of the total) and Angolans with 6.8 percent.
Over the past decade the number of immigrants from South America has increased dramatically from 17 percent to 29 percent of all immigrants but this is largely down to people coming to Portugal from Brazil with not many coming from other countries.
Immigrants from Asia have also increased in the past 10 years up to 2.6 percent with most of these foreign residents coming from China to Portugal.
As the number of Brazilians, Ukrainians, Romanians and Chinese immigrants increases in Portugal the number of Angolans was found to have fallen dramatically by 27.2 percent – representing a decrease of around 10,000 people.
The number of foreign residents in Portugal is however hard to determine conclusively as many people are living and working in the country illegally and do not have the correct paperwork.
Not all British nationals living in Portugal are registered as residents and may live for most of the year in Portugal but return to the UK where they are properly registered.
