Over a third of Leave voters have said they would sacrifice their own job, or those of family members, if it meant bringing the UK out of the European Union.
Some 39 per cent of people who voted for Brexit said personal job losses were a price worth paying for leaving the bloc - and that figure rises along with the person's age.
While just 25 per cent of Leave voters aged 18-24 said it was acceptable, that doubled to half of people aged 65 or over, according to YouGov.
The numbers were even higher when asked about the country as a whole. Some 71 per cent of the older bracket and 46 per cent of the younger saying "significant damage to the economy" would be a price worth paying.
On average, 61 per cent of Leave voters said they believed in Brexit at any cost, while just one in five said the price was too high.
But it's not just Leavers who were committed to their views regardless of the outcome. A third of Remainers said they would back their stance in the face of significant damage to the economy - although this was less than the 38 per cent who said it was too high.
When split on party lines, Conservatives came out as the most committed Leavers, with 47 per cent saying they would take the personal hit, compared with 23 per cent of Labour supporters, while 68 per cent said the economy could suffer for Brexit against 38 per cent.
Politicians and campaigners on both sides have accused the other of pushing a position that will sabotage the UK's economy.
Job losses are becoming a genuine threat as the Article 50 deadline looms.
A report published today claims that Brexit and the relocation of euro clearing could force up to 40,000 jobs out of the City. Yesterday's announcement that freedom of movement would come to an end from March 2019 was dubbed a "disaster" by business leaders.
A transitional period is increasingly viewed by many as the best way to avoid harming domestic growth, although this is by no means certain, having been the source of some conflict within government.
