A poll by research consultancy nfpSynergy, which surveyed 1,000 adults in Britain in March, found that while the overall level of public giving and volunteering was party-neutral, a donor's choice of charity was related to their political allegiance.
Liberal Democrat supporters were significantly more likely to donate to children, animals and the environment, the study found.
However, their gifts to hospices and charities for older people was well below average.
Conservatives favoured hospices over charities for children and youth, social welfare and homelessness.
Labour voters were more likely to support services for older people, as well as health and disability issues.
Rebecca Molyneux, researcher at nfpSynergy, said it would be interesting to see how such differences could affect party policy, especially within the coalition government.
