Eden was the first to declare at 2.05am, Allerdale followed at 2.45am, Carlisle at 3am, South Lakeland at 3.10am, Barrow at 3.25am and Copeland at 4am.
Copeland was the last to be declared because its count did not get under way until 1.35am, after ballot papers had to be verified twice due to a discrepancy over three extra papers were found during the initial checking process.
Mark Little, the Leave campaign's Copeland spokesman, said: "This is a superb result and I have been very encouraged that our canvassing has been reflected in the polls.
"We are very appreciative of the support given to the campaign from Copeland and Cumbria as a whole."
Before the declaration of the result, Nick Ford, of the Leave campaign, said: "In Cleator Moor where I'm based turnout has been very high - they were queuing outside polling stations at 7am - and almost everyone I've spoken to says they want to leave."
Gillian Troughton, a spokeswoman for the Remain campaign, said: "The result is probably what we had been expecting but it doesn't make it any less depressing."
The polling station to receive the highest turnout was at Corney with 83.33 per cent and the lowest at Mirehouse Community Centre with 50.15 per cent.
Allerdale's count took place at Workington Leisure Centre.
Hugo Graham, member of the Conservative Party and Leave campaigner, said: "I'm very pleased with the result.
"It goes with what I've seen throughout the county during the campaign and what I've seen at the side of the roads. This is what I expected. This is a very satisfying result."
Workington MP Sue Hayman, who backed Remain, said: "I'm really pleased with the turnout because for the result to be totally legitimate we need a high turnout.
"To be honest the Allerdale result is kind of what I expected. I've been out and about talking to a lot of people and from conversations I've had, this is pretty much what I expected.
"What we need to do now is make sure that whatever the result, Allerdale gets what it needs from the Government, because I think the vote reflects that people aren't satisfied with what the Government is doing for them here."
Remain campaigner Phill Roberts said: "I'm pleased the country had the opportunity to vote.
"This referendum is a conversation we should have had some time ago. The referendum has raised some of the worst aspects of society, it will take a long time to heal."
Carole Armstrong, also of Remain, said: "I don't think people realise what will happen if we leave the EU. We'll lose all our contacts with the other countries. All people are thinking about is immigration, but immigrants have been here for years. If you want a job you'll get one. Let's hope we'll get our act together after this vote."
Celia Tibble, mayor of Allerdale and Labour Party member, said: "I believe that the workers and families in West Cumbria and Workington will lose massively if the country votes out."
David Wilson, of Leave, said: "This vote has taken a long time to come. We were promised this vote seven years ago. I don't believe the EU is a democratic state, they're trying to create a federal state where Great Britain will be a province.
"We fought two world wars for democracy."
In Eden, Remain campaigners at the Penrith count were philosophical about the result. Sheelagh Delaney was count sub-agent.
She said the team had done everything it could to spread to word.
She added: "I think it's a good result for the Remain campaign actually, especially with a high turnout.
"We've had members in town centres, we've hosted public meetings, we've had wonderful speakers come to support us. We've pushed and pushed.
"I think it's a good result for the Remain campaign actually, especially with a high turnout."
Vote Leave supporter Phil Douglass, who was at the Carlisle count at the Sands Centre, said he was surprised when the Eden result was announced.
He said: "I was expecting them to vote Remain. For them to convincing go for Leave it is a big shock. We didn't bank on it. We thought Carlisle would choose to Leave and it is looking like it is going to be, but not Eden."
Oliver Coulson was at the Penrith count.
He led the Vote Leave campaign for Cumbria while completing his A-levels,
"It's been a very fair and very decent process. I think a minority of Leave voters might be looking for an excuse for why their county hasn't gone do well but here in Cumbria we've run a decent campaign, an honest campaign and I'm proud of what we've done here.
"We're absolutely delighted. Considering we had a 75 per cent turnout here in a very small electorate we're very happy."
In Carlisle, Remain supporter John Mallinson, a Conservative, said: "We expected that Leave would win in Carlisle by a significant margin."
Vote Leave campaigner and Conservative Fiona Robson said: "I'm not surprised because Cumbrians are based on common sense and common sense says to get out of Europe.
"The rest of the country may be swayed by the nonsense but Carlisle and Cumbrians are salt of the earth. I'm absolutely delighted about Carlisle's result."
Meanwhile Carlisle MP John Stevenson admitted he was "always a sceptical Remainer" but believed the EU will reform.
He added: "At the end of the day we will have to do what the British people instruct us to do.
"It has got to be good that there is a high turnout. It means that the British people have been engaged."
In South Lakeland, the only area that voted to Remain in the EU in Cumbria, Councillor Mark Wilson, Labour member on Cumbria County Council, South Lakeland District Council and Ulverston Town Council, said: "I'm happy. I want us to stay. I'm pleased that the vote has reflected that ambition.
"It's been called and people have given it their consideration and overall the public have voted to Remain in solid and sound economic progress."
David Walker, South Lakeland Vote Leave and Ukip referendum agent, said: "I'm pleasantly surprised that the vote was as close as it was in a solid Lib Dem area.
"This proves that the various campaigns got their message through well and people now understand the EU a lot more than they previously did."
In Barrow, Nigel Cecil, vice-chairman of Ukip in Barrow, said before the count: "We're feeling confident because this town represents the working people but the Labour Party has sold them out and Ukip are here to fill that hole.
"This is a once-in-a-lifetime opportunity and it's important to all of us. We have to be confident and we believe in the people of this borough."
Anne Burns, vice-chairman of the Labour Party, said Mr Cecil's views were unfair.
She said: "I don't think Labour has sold Barrow down the river.Being in the EU is better for workers' rights, better for jobs and prosperity and if we vote to leave we're jumping into the unknown."
The country has been divided into 382 voting areas, each of which will declare its own result.
The result for the whole of the UK will be announced only when all 382 areas have declared.
Nationally, if there is a clear majority for one side, it is expected the overall result will be announced around 6am tomorrow.
But if the results keep both sides neck and neck, it might not be until the final declaration is made in Manchester that we know what the UK has decided.
You can follow all the action from the counts here, as it happens and tell us what you think about the referendum, how the campaigns have been run and, if you like, which way you've voted and why.
