Kuznets demonstrated this relationship using cross-sectional data. However, more recent testing of this theory with superior panel data has shown it to be very weak. Kuznets' curve predicts that income inequality will eventually decrease given time. As an example, income inequality did fall in the United States during its High school movement from 1910 to 1940 and thereafter.[citation needed] However, recent data shows that the level of income inequality began to rise after the 1970s. This does not necessarily disprove Kuznets' theory.[citation needed] It may be possible that another Kuznets' cycle is occurring, specifically the move from the manufacturing sector to the service sector.[citation needed] This implies that it may be possible for multiple Kuznets' cycles to be in effect at any given time.
