The given chart illustrates the comparison between the production of bicycles and cars throughout a fifty-year period.
In summary, a number of sales of both vehicles (bicycles and cars) had a considerable growth over the entire period; however, bicycle demand increased far more than car demand.
In 1950, both consumer demand for bicycles and cars was barely similar ( about 500 000). While, need for bicycles began to grow in 1960, reaching a figure of roughly less than million. Futhermore, the difference between the market demand for both vehicles rose sharply in 1970. Meanwhile, the number of bicycle sales reached approximately 2 million, cars were sold around million.
Only after 1970, bicycle demand did considerable rise. The significant growth in bicycle sales occurred in 1980 (typically more than 100 million). In addition, after two-decade period, the number of bicycle sales became much more than 200 million. Between 1980 and 2000, market demand for cars grew slightly (from 25 million in 1980 to 50 million in 2000).
