As a poet, I am perpetually interested in shifting the margins and locating community, particularly surrounding increasing gender and racial equality in the production, publication, and dissemination of poetry. Here are a few venues that are rooted in activism and collaborative in nature, to which I have either made contributions or paid attention:
Every year, a large group of volunteers manually perform a “VIDA Count,” tallying major publications’ author bylines according to gender representation, in order to increase awareness of the gender disparity prevalent in publishing. In 2015, they added a “Women of Color Count” to account for ethnic disparity. 
For the charts:

I am not currently a counter (someone who volunteers to count), which requires a certain time commitment, but I have plans to join later this year.
There are various listicles or single-authored resources pages on possible venues and markets for publication, but this open-access google drive spreadsheet allows for everyone to add their own knowledges and populate the list, and I have added to the list myself.
This is another open access effort to increase the visibility of writers of color. I have not added myself to the list (yet), but I have suggested to friends that they do.
From the website: “Don’t you hate when editors use “I don’t know enough writers of color” as an excuse to back up the homogeneity of their publications? We do too. Here’s a fix, brought to you byDurga Chew-Bose, Jazmine Hughes, Vijith Assar, and Buster Bylander. Need someone to cover politics? Here you go. A correspondent in Chicago? We’ve got you covered.
We aim to create more visibility for writers of color, ease their access to publications, and build a platform that is both easy for editors to use and accurately represents the writers. The response so far has been overwhelming (thank you!) and we welcome further feedback from both camps, but please realize that this site is run by volunteers and is a work in progress. We still need help fixing mistakes and keeping things running smoothly.”
