**TL;DR**: The claim is **true** within reasonable rounding margin. 

According to the [Inter-Parliamentary Union](http://www.ipu.org/english/whatipu.htm), the US House of Representatives has the [69th-most women among all lower houses](http://www.ipu.org/wmn-e/classif.htm). In terms of ranking among nations, **the US is ranked 89th in terms of female members of (lower) houses out of 188 countries**. The US is also **ranked behind    Cuba (5th), China (51th), Iraq (35th) and Afghanistan (30th)**. Thus, the claim appears to be true.

*Shouldn't we compare members in both houses, rather than just compare lower houses?* 

Well,  **if both houses were counted together, where applicable, the US would actually *lose* 8 ranks**: Barbados, Antigua and Barbuda, St. Lucia, Bahamas, Grenada, Swaziland, Ireland, and Zimbabwe all would get more than 17% representation. 

*Shouldn't we compare the US to something more relevant than, say, Bhutan, or to places were parliaments have any relevance, unlike e.g. Belarus?*

 - **Compared to its direct neighbours, the US comes in third out of three.** Mexico is #35 and Canada #41, when ties are counted as ranks (I didn't correct for combined houses).

 - **Compared to the EU, the US comes in 22th out of 27+1**. The US beats 5 out of the 27 member states: Slovenia, Slovakia, Romania, Malta and Ireland (which would rank ahead of the US if we were to count women in both houses).

 - Just for fun: **Compared to the Arab League, the US comes in 8th out of 21+1**. Almost top third! Note that I didn't count Palestine, so there are 21 instead of 22 members. Honestly, I expected the US to do better here. 



As an aside, [this report compiled for the parliament of Canada](http://www.parl.gc.ca/content/lop/researchpublications/prb0562-e.htm) mentions how election procedures can help or hurt women (and other underrepresented groups):

> Canada’s electoral system is a “single-member plurality” or “first-past-the-post” system. In every federal electoral district, the candidate with the most votes wins a seat in the House of Commons and represents that riding as its Member of Parliament. It has been argued that this system tends to discourage the election of women and other under-represented groups.
