Kensington will have the fewest first-time voters in the country at May's General Election.
According to figures released by the Office for National Statistics, there are 768 people on the constituency's electoral register who have turned 18 since the last election in 2010, but 58,316 people on the register in total.
This means only 1.3% of those people will be voting in a general election for the first time.
No other constituency out of 591 in England, Wales and Northern Ireland is set to have a lower proportion of first-time voters.
The figures come in the same week the constituency’s MP, Sir Malcolm Rifkind, stepped down due to the ‘cash for access’ scandal when he told a fictitious Chinese company he was ‘self-employed’ despite earning £67,000 as an MP. He has since said he was referring to his outside interests, not his MP job.
Out of the west London constituencies, Hampstead, Kilburn and Westminster North also have very low proportions of first-time voters with 1.9% and 2% respectively.
Ealing North, however, currently has the highest proportion of first-time voters on the electoral roll with 4.9% or just under one in 20 eligible voters having turned 18 since May 2010.
MP for Ealing North Steve Pound said: "It shows that Ealing North is a young vibrant community.
"It also shows I'm right to send an 18th birthday card to each of my constituents with information on how to participate in the democratic process."
Registering to vote has changed this year, with individuals having to register online instead of one person registering for a household.
In England, 3.8% of the electoral register is made up of first-time voters, in Wales the figure is 3.2% and for Northern Ireland it is 3.1%.
The figures are correct as of December 2014.
