As the nation gears up for Donald Trump's inauguration in the coming days, several hundreds of thousands of women (and men!) are gearing up to protest Trump's position in the highest level of office in the land in the Women's March On Washington.

The purpose of the demonstration, as stated by its organizers, is “to come together in solidarity to express to the new administration & congress that women’s rights are human rights and our power cannot be ignored.” It's likely that these people will not be ignored (at least not by the media), as this is poised to be the largest demonstration against Trump during his inauguration weekend. Demonstrators are demanding not only equal rights for women under a president accused of sexual harassment, but also immigration rights, and the ceasing of police brutality. Here's what we know about the march so far, as shown by the numbers.
