The relationship between GDP growth and unemployment rate is indicated in Okun’s law. The law suggests that in order to decrease 1% unemployment rate, there should be 4% increase in GDP in a year.
In the US:
Few statistical data are as below:
| 
 Year  | 
 GDP growth rate  | 
 Unemployment rate  | 
 Change in unemployment rate  | 
| 
 1996  | 
 3.8%  | 
 5.4%  | 
|
| 
 1997  | 
 4.4%  | 
 4.7%  | 
 [(4.7 – 5.4) / 5.4] × 100 = -12.9%  | 
| 
 1998  | 
 4.5%  | 
 4.4%  | 
 [(4.4 – 4.7) / 4.7] × 100 = -6.3%  | 
| 
 1999  | 
 4.8%  | 
 4%  | 
 [(4 – 4.4) / 4.4] × 100 = -9.1%  | 
| 
 2000  | 
 4.1%  | 
 3.9%  | 
 [(3.9 – 4) / 4] × 100 = -2.5%  | 
| 
 2001  | 
 1%  | 
 5.7%  |

| 
 2018  |

 3.9%  | 
|
| 
 2019  | 
 2.3%  | 
 3.5%  | 
 [(3.5 – 3.9) / 3.5] × 100 = -11.4%  | 
As per data, in the years when GDP growth rate are more than 4%, unemployment rate decreases surely (as per the last column) and such decreases are atleast less than 1% rate.
Year 2019: Unemployment rate decreases more than 1% although the GDP growth rate is not 4%. This is the breach of Okun’s law.
Therefore, the law is not universally true every time.
