LOL!! I take it that was a typo,
No typo!!. 2016 statistics were NI to RoI 30% , NI to rest of world (inc. mainland UK) 47%. NI to EU 23%
53 is bigger than 47 .
..Irish times june 21 2018 .... based on NI figures. .There is a nice graphic as well...
"2016, 30 per cent of Northern Ireland’s exports – £2 billion (€2.3 billion) – were sent to the Republic; a much greater percentage than the goods going the other way. Just 1 per cent of the Republic’s exports, worth £1 billion, went to Northern Ireland.
However, England, Scotland and Wales remains Northern Ireland’s single largest primary market for external sales, even though the Republic is its largest export market.
Northern Ireland exported almost twice as much to the Republic as it imported, with businesses making 758,000 cross-Border deliveries southwards in 2016, compared with 410,000 deliveries from the Republic."
