Senior researcher Dr Carlos Vargas-Silva said: "The biggest change has been the increase in the Polish-born population, which increased more than twenty-fold, becoming the biggest migrant group in Wales.
"This has been particularly apparent in Merthyr Tydfil which saw the second largest percentage increase in its migrant population of anywhere in Great Britain."

Jolanta Atkinson, chair of the Anglo-Polish Society for Chester and North Wales, has lived in Wales for 40 years.
She said: "When I first came to Bangor, all those years ago, I was the only Polish person. Now it's a very big community.
"I can see the difference over the last 10 years, where people can speak English now and they send their children to the local school, and they are helping the economy by working and paying taxes.
"The majority are young people who are willing to work hard and bring up their families in Wales."
She said the chance of greater opportunities for work was the main reason for people wanting to live in Wales.
She added: "Wales is very welcoming and I know people who have praised it as a fabulous country, and they really mean it.
