"Women are much more likely to see their wealth as something they can do good with than to go out and buy toys - boats, fast cars, jets and so on," Philip Beresford told Third Sector.
Twelve women are mentioned, eight as part of a couple, in this year's 100-strong Sunday Times Giving List, an offshoot of the Rich List. According to Beresford, the trend for female entrepreneurs to give is set to continue.
"Charities need to target women entrepreneurs because they're beginning to make their mark," said Beresford. "The balance in business is tilting in favour of women."
Beresford also pointed out that women entrepreneurs could be harder for charities to target. "They tend to be more low-key and they don't want to talk about what they do as much," he said.
