This map shows every place in the US that has ever had a woman in Congress

Nearly one hundred years after the first woman was elected to Congress, three states have never had either a woman senator or representative:

Vermont, Delaware, and Mississippi have never elected congresswomen.

As you can see above, Vermont, Delaware, and Mississippi have never been represented by a woman.

Now, let's break it down by legislative body. Along with the three states mentioned above, Iowa and Alaska have also never had any women in the House. And 22 states total haven't had a woman senator.

Washington, DC, elected Eleanor Holmes Norton as the District's non-voting delegate to the House in 1991 and has reelected her ever since.

And of the US territories that elect non-voting delegates to the House of Representatives, American Samoa, Guam, and the Virgin Islands have elected women delegates, while Puerto Rico and the Northern Mariana Islands have not.

You can look up your own address with our searchable map below, and we'll tell you about any women who have represented your location in Congress.

Notes: The searchable map was made possible largely through a set of district boundaries provided by United States Congressional District Shapefiles, an NSF-funded project to map congressional redistricting over time. The project includes boundaries from the First Congress in 1789 through the 113th Congress that ended in 2015. I used more recent US Census data to grab boundaries for today's 114th Congress, which ends in 2017, and a roster at Voteview to match up historical district numbers with a list of women Congress members provided by the Office of the Historian.

Results for House representatives are our best guesses based on cartographic records of congressional districts. Locations on the edge of a current or former congressional district may inaccurately give results for an adjacent district instead.

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple of big issues with relying on ads and subscriptions to keep the lights on:

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. And we can’t do that if we have a paywall.

So even though advertising is still our biggest source of revenue, we also seek grants and reader support. (And no matter how our work is funded, we have strict guidelines on editorial independence.)

If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today? Any amount helps.
