Select the correct word(s) that best fit the sentence: The number of people __________ from other countries to the United States has caused a shift in unemployment in the textile market.

The word 'emigrating' is the correct choice in this sentence as it refers to people leaving their own country to settle in another. In the context of the sentence, 'emigrating' is the appropriate term to describe individuals moving from one country to another, which has impacted the job market in the United States. 'Immigrating' and 'migrating' are not the most suitable choices because the sentence specifically talks about people leaving their countries to go to the United States, making 'emigrating' the correct word to use.
