PITFALLS Change in levels versus rate of change When studying economic growth, it’s vitally important to understand the difference between a change in level and a rate of change. When we say that real GDP “grew,” we mean that the level of real GDP increased. We might say that U.S. real GDP grew during 2007 by $229 billion. If U.S. real GDP in 2006 was $11,295 billion, then U.S. real GDP in 2007 was $11,295 billion + $229 billion = $11,524 billion. We could calculate the rate of change, or the growth rate, of U.S. real GDP during 2007 as: (($11,524 billion − $11,295 billion)/$11,295 billion) × 100 = ($229 billion/$11,295 billion) × 100 = 2.03%.

8 of 52 Growth Rates How did the United States manage to produce over six times more per person in 2007 than in 1907? A little bit at a time. Long-run economic growth is normally a gradual process, in which real GDP per capita grows at most a few percent per year. From 1907 to 2007, real GDP per capita in the United States increased an average of 1.8% each year.

9 of 52 Growth Rates The Rule of 70 tells us that the time it takes a variable that grows gradually over time to double is approximately 70 divided by that variable’s annual growth rate.

11 of 52 ►ECONOMICS IN ACTION India Takes Off India achieved independence from Great Britain in 1947, becoming the world’s most populous democracy—a status it has maintained to this day. Despite ambitious economic development plans, India’s performance was consistently sluggish. In 1980, India’s real GDP per capita was only about 50% higher than it had been in 1947. Real GDP per capita has grown at an average rate of 4.1% a year, tripling between 1980 and 2007.
