1. The 1920s: a time of prosperity During the 1920s, the United States’ economy grew significantly.

2. 1. Manufacturing output rose more than 60% 2. Gross national product (total of goods and services) rose 5% a year 3. Industrial output per worker grew 33% 4. Per capita income grew 30% with virtually no inflation

3. To put that into perspective… A factory used to make 200 chairs in a week. Now that manufacturing output rose 60%, the factory makes how many? 200 X 1.6 ( 100 % of original plus 60% increase) = _____ 320 chairs

4. Output per worker grew 33% (1/3) in the 1920s, so… Jimbo works at a comb factory and he made 900 combs a day. How many does he make now? 900 X 1.33 (1 1/3) = ______ 1,200 combs! Which means more combs, and less tangled hair for everyone!!!!

5. This was due to many different reasons: During WWI, the European economies were destroyed. This left the U.S. as the only major industrial nation. The presidents of the 1920s put business at the top of their list of priorities for the country. The growth of advertising in mass- circulation magazines such as Time, Reader’s Digest, and the Saturday Evening Post

6. More reasons for economic boom… Technology innovations allowed for expansion, particularly in the auto industry. -1.5 million cars sold in 1920, 5 million in 1929 - with more cars, people could spread out Cheap, readily available energy sources (coal, oil) made expansion affordable.

7. Possibly the most significant advancement was the assembly line.
