I think that opinions of single women have changed over the years. Many years ago, single women were often viewed in a negative way. It was assumed that something was wrong with them-why didn't a man want them?
Now days this view has changed. Single women are generally viewed as being more independent and career focused. More and more women are waiting until they have established careers before they are getting married and having children.
Certainly, American society's views on single women have definitely changed over time. For a period of time, single women were viewed with a bit more negative perception. Some were seen as "incapable" of "landing a husband" or seen as if they possessed some handicap or condition which made them seem "less" of a women for not marrying. Over time, this perception has thankfully changed in that there are more women who are choosing to be single out of choice and asserting their own voice in the process. In making it a decision that has been made by women's own autonomy, mainstream American social orders no longer dictate that a women has to be married.
I'll assume the rest of your question as being, what is society's image of single women in the United States? Modify your question if you mean something else and I'll adjust the answer.
There are several societal views on this subject. Those who are single through school and college are supported by society, as opposed to those who marry young, which most consider a mistake. Exceptions: segments of the Latino population and the Mormon Church.
Another view is that women who are single into their thirties are somehow failures. This used to be more prevalent in older times, but is still around. The number of people who never marry is consistently rising over time, but the social stigma remains.
There is another view, by women of women that often views unmarried females as independent and leaders.
single women with in a particular society found totally different in other. whereas country like India still believe that single women are mainly curse by their destiny. Still single women are gave continuous effort to established their status in society with a respect but till now its found very hard.
