New figures from the 2011 census suggest Polish is the second most common language spoken in England and Wales.
The study revealed that there are now more than half a million people who speak Polish as their first language.
Most people speak English as their main language - with 92% speaking it as their mother tongue.
But there are lots of other languages being spoken too, such as Punjabi, Urdu and Arabic.
The census is a big study taken every ten years that helps us learn more about our country and how we live.
Results from the 2011 census showed that:
- There's been a rise in the number of Polish speakers to 546,000 people.
- The number of people who speak Welsh has fallen to 562,000.
- There are 138,000 people living in England and Wales who don't speak English at all.
