Directions:
Population
of the U.S. from 1930 to 1980

1930: 123,202,624 
1940132,164,569

1950: 151,325,798 
1960:
179.323,175

1970: 203,302,031 
1980:
226,545,518

Your task is to present a report showing the change in population between
1930 and 1980.
1. Round the data, then make a table and line graph (not a bar graph)
to display the data in a way that would best highlight the change.
2. Write two statements about the change in population in the U.S. between
1930 and 1980.
3. Using the information from your chart or graph, write and solve an
addition or subtraction word problem.
