**Dataset population:** Persons aged 3 and over **Age upon arrival in the UK** The age of arrival in the UK is derived from the date that a person last arrived to live in the UK and their age. Short visits away from the UK are not counted in determining the date that a person last arrived. Age of arrival is only applicable to usual residents who were not born in the UK. It does not include usual residents born in the UK who have emigrated and since returned; these are recorded in the category 'Born in the UK'. **Proficiency in English** Proficiency in English language classifies people whose main language is not English (or not English or Welsh in Wales) according to their ability to speak English. A person is classified in one of the categories: * Can speak English very well * Can speak English well * Cannot speak English well * Cannot speak English This question was handled slightly differently in the England and Wales censuses. In the English census a tick box was used in Question 18, asking 'What is your main language?', giving the option of 'English' or 'Other'. In the Welsh census, a tick box was used in Question 18, asking 'What is your main language?', giving the option of 'English or Welsh' or 'Other'. Those who ticked 'Other' would be asked about their ability to speak English. A consequence of this is that a person who reports their main language to be Welsh and completed the Welsh census, will not be asked about their ability to speak English. Whereas a person who indicates that their main language is Welsh and lives in England would be asked about 'their ability to speak English'.
