The poster below was created in 1917: poster of a woman sleeping while dressed in clothing that resembles the u. s. flag. the poster reads, civilization calls every man, woman, and child. public domain with which social change is this poster associated?

The social change associated is that the status of women had risen.

As we can see from the source, the women is dressed in the US dress meaning that she played an important role for US.

The next clue that support the statement is that civilization calls for not only men but child and women. From it we can see the government no longer only seen importance in men but in women as well.

The background in that in the past years in US,women had low social status and was seen to only be wife to take care of children. They didn't have the right to vote,to voice out,to take up a important job etc.

In 1917,however, due to the occurance of WWI,much labour was needed for manufacturing but the men were to be soilders. Thus women took up the labour work and contribute to the society. Their contribution led to the uprise of their social status.

Hope it helps!
