evidence: On 7th April 2017, Irish foreign minister Charles Flanagan stated to BBC News, "Over 30,000 people cross the Ireland-Northern Ireland border daily." [...] When we asked about the claim that 30,000 people cross the border on a daily basis, Annmarie O’Kane (Border People project manager at the Centre for Cross Border Studies) commented: "The Minister’s estimate of the level of cross-border mobility in this region may be somewhat conservative." She went on to explain that "the lack of exact statistical data and analysis on cross-border mobility is a very common problem in many EU border regions". [...] With these statistics in hand, we can begin to see the growing numbers of people crossing the Ireland-Northern Ireland border on a daily basis. It is therefore reasonable to conclude that the estimate of 30,000 people crossing the border every day for work is accurate.
