mind when thinking about immigrants. Members of this category may or may not be foreign nationals, and, depending on their parents' status, may or may not be subject to Immigration Control, so under some definitions, some would qualify as immigrants. But by the birthplace criterion or the "movement" criterion used in official net-migration statistics, UK-born children of immigrants do not themselves qualify as immigrants. 2.2 Perceptions: Length of stay By the international definition of migration -- used by the UK government in official statistics on immigration, emigration, and net-migration -- anyone who moves across national boundaries for at least one year is considered a "long-term international migrant." Less than one-third of the public in Britian, however, say that they normally are thinking about temporary migrants when thinking about "immigrants." Members of the public appear more likely to think of permanent immigrants rather than temporary ones when thinking about immigrants, as Figure 3 shows. A majority (62%) said that they normally thought about people coming to stay in Britain permanently, while the temporary migration categories were each chosen by 30% or fewer. There was no statistically significant difference in perceptions of people staying for between one and five years, and of people staying for more than five years but not permanently. Responses fell to 15% for people staying less than one year. Figure 3 Although permanent immigration predominates in public perceptions of immigrants, temporary immigration accounts for the majority of annual arrivals according to ONS data (in LTIM Table 2.09).
