This chart shows if Britain doesn't leave the EU in 2016, it may never happen
A new chart published by Ipsos MORI shows that the Leave campaign needs to win the upcoming referendum if Britain is to ever leave the European Union.
This is because a bulk of Eurosceptics are going to die out soon and are going to be replaced by a generation of people who are more likely to want to stay in the EU.
The chart - which is based on data gathered by a Eurobarometer survey - shows that young people are generally more trustworthy of the 28-nation bloc.
On the flipside, it also highlights how the most Eurosceptic people in Britain's society were born either before or in the decades closely following World War II.
According to the chart, just over 30% of Generation Y (also known as millennials) tend to trust the EU. This is more than double the share of pre-war and "baby boom" people who feel the same - which is around 15%.
The survey said that 56% of 18-34-year-olds believed Britain should stay in the EU, compared to just 33% of over respondents over 55 who felt the same.
Prime Minister David Cameron described the referendum as a "once in a lifetime" political event last week. This chart suggests that for Brexit campaigners, the stakes are probably even higher than that:
This chart suggests that for Brexit campaigners, the stakes are probably even higher than that - now or never.
If so, then Leave campaigners have a lot of work to do in the next five weeks if they are to make political history.
Matt Singh - the polling analyst who rose to fame as the only person who correctly predicted the General Election outcome - said in his latest referendum forecast that the probability of a Brexit is currently less than 20%.
New phone polls published this week by ICM, Ipsos MORI, and ORB showed big leads of 8, 18, and 15 percentage points for the Remain campaign, too.
As things stand, public opinion isn't in Leave campaigners' favour, and with just over a month until voting day, time isn't exactly on their side either.
