It's been a very busy century for women since the first International Women's Day, to say the least, not to mention a complex one. So today, on the 100th year anniversary celebration, it's interesting to consider where we are and where we have been. For instance, in most parts of the Western world, women live longer and healthier lives than men; yet throughout their lives, they still only earn about 84% of what men do.As this video from WeAreEquals.org points out, "women are responsible for 2/3rds of the work done worldwide, yet earn 10% of the income and own about 1% of the property." It goes beyond the financials, as well: 70 million women go without a basic education every day of their lives and 60 million women are sexually assaulted every year.While it's momentarily comforting to turn to recent reports on how women fared better during the "man-cession" or on how a growing number of households have a woman as the primary breadwinner, these short-lived (and potentially media-overblown) instances of women "winning" over men are hardly grounds for a dismissal of the pervading differences that exist between women's and men's lives, especially in regard to women's sexual health. According to the Kinsey Institute, an estimated 100 to 400 million women are still subject to Female Genital Mutilation around the world every year, and just in the United States alone, a woman is raped every two minutes. Hence the importance of International Women's Day!For those of you who are fond of social media, the International Women's Day website offers a number of ways to call out the day on your Facebook or Twitter account. You can also participate, either virally or in person, in the "Join Us on the Bridge" event, connecting women today across the globe. Here's a list of more philanthropic efforts that can help you get involved as well. Check out this amazing wishlist entitled "All I want for International Women's Day is..." and get inspired to write some wishes of your own. And for a more personal touch, post a status update on your Facebook or send out an email to your family and friends, telling them about the amazing women who have touched your life. Or tell a woman in your life how she's made it bigger and brighter! In fact, I think there's a few ladies I'll be emailing right now.
