Child poverty, disability and health have topped a list of causes to which Britons would be most likely to donate £1 million - but gender equality, drug addiction and culture have been overlooked.
The poll, which investigated philanthropy in the UK, found that 18 to 24-year-olds were among the most charitable, with more than two in three saying they regularly donate.
The study surveyed 2,036 people, revealing that 71% of young adults would give up £2 a day for charity. By comparison, just under half of those over 65 said they would do the same.
Participants were then asked to divide £1 million between 10 worthy causes. Health issues, including medical research and care, were given on average more than a quarter of the funds available - a mean donation of £275,331.13.
Child poverty and disability charities were the next biggest winners, each receiving £174,100.91 and £147,821.63 of the hypothetical funds.
The remaining 40% was given to education, housing and environment charities. Arts, culture and sport, criminal justice and gender equality were almost completely ignored.
Of the £1 million on offer, those polled gave on average just £22,000 to gender issues, £32,000 to drug and crime rehabilitation and £39,000 to the arts and sport.
Chip Somers, chief executive of Focus 12, an addiction charity headed by controversial comedian Russell Brand, said: "It doesn't surprise me in the slightest. There is still a very wildly held belief in this country that addiction is a self-inflicted illness and people should just pull their socks up and get better.
"I have always said jokingly that as a charitable cause we come just above paedophiles and immigrants - and I don't think actually that's far away from the truth.
"When you are competing with cuts in resources to mainstream social services, nobody is going to stand up and say they would like more money to be spent on drug addicts and criminals."
When asked to consider distributing £500 to the same 10 issues, people offered an even smaller per cent to the three areas, with an average of £7.19 going to gender equality and £9.75 to criminal justice.
The research was completed by Populus for the City of London Corporation's charity City Bridge Trust ahead of a philanthropy exhibition that opens on Wednesday.
Sandra Horley, chief executive of domestic violence charity Refuge, said: "We struggle to raise voluntary income for our work with abused women and children. The issue of domestic violence is still so shrouded in myth and misunderstanding.
"Research by New Philanthropy Capital has shown that one UK animal charity received more support annually than the three largest women's charities put together.
"The truth is that Refuge urgently needs public support. Ongoing cuts to local authority budgets are eroding our statutory income day by day, putting many of our services at risk of closure."
