Final answer:
The statement regarding more people emigrating from the US after 1950 is false. Data indicate a substantial increase in the number of migrants living in the US, with about 45 million foreign-born people residing in the country.
Step-by-step explanation:
Based on the data provided, the statement that 'after 1950, more people emigrated from the United States' is false. The information shows that the number of migrants living in the United States has increased significantly, not decreased. Specifically, from 1990 to 2013, the number of migrants in the US rose from one in six to one in five. Also, the figures state the United States is home to about 45 million foreign-born people, compared to only about 3 million US citizens living abroad.
This suggests a substantial net influx of immigrants rather than emigration. Moreover, the data from Figure 15.7 indicates that the number of immigrants each decade declined between 1900 and the 1940s, then rose sharply through 2009 and only started to decline from 2010 onward, but the overall trend is still an increase in immigration into the US.
