What differences, if any, are there between 婦 and 女?


I came across 婦 from [this English-language Wikipedia
article](http://en.wikipedia.org/wiki/Comfort_women).

Jisho.org says that 婦 (which contains 女 in it) can mean married woman, but it
can mean woman or lady, and it then lists words such as 婦警 for policewoman and
婦長 for head nurse, ie roles where I assume her marital status isn't relevant.

What differences, if any, exist between 婦 and 女, outside of the context of
someone being married?




I honestly don't think any assumption about policewomen being married lies
behind e.g. the word 婦警.

As [Goo](http://dictionary.goo.ne.jp/leaf/jn2/189407/m0u/) says, one meaning
of 婦 is "married woman", another is "working woman" (although those two might
be negatively correlated).
