Here on Ekklesia, we have good reason for knowing that women hold up half the sky.
But they get less than half the credit, and according to the latest UN stats, only a fraction of the income and wealth. The official IWD site is here . And the US ecumenical agency Church World Service  has done a round up of development initiatives  in Africa, Latin America and elsewhere, run for and by women.
Demographic data on women and men vis-a-viz society, development and politics can be found here .
Turning to the religious angle, there is a good bibliography on women and theology at the Women's Studies Section of theAssociation of College & Research Libraries / American Library Association site.
