It's clear from the statistics that women are becoming more wealthy than ever (now making up 256 of 2208 places in Forbes' 2018 list of billionaires) with private wealth of $51trn in the hands of women in 2015, which was up by 50% from the previous 5 years.

Although there is a long way to go, what is extremely encouraging is how those women are using that money, giving away almost double of their wealth to charitable causes versus men.

Women are also more likely to engage in "sustainable" investing (84% vs. 67%) and to work collaboratively in their giving.

On International Women's Day, and every day, we should be shouting about, and celebrating the increasingly important and influential role women are playing in philanthropy.
