GDP Growth Rate in the United States averaged 3.25 percent from 1947 until 2015, reaching an all time high of 16.90 percent in the first quarter of 1950 and a record low of -10 percent in the first quarter of 1958.
The economic growth rate provides insight into the general direction and magnitude of growth for the overall economy. In the United States, for example, the long-term economic growth rate is around 2 to 5%. Lower economic growth rates are seen in most highly industrialized countries. Fast-growing economies, on the other hand, see rates as high as 10% although this rate of growth is not likely to be sustainable over the long term.
