The long-term natural rate of unemployment measures the rate of unemployment arising from all sources except fluctuations in aggregate demand. This indicates GDP levels and long-term economic health.
The data shows autocorrection and a non-normal distribution. The data should be differenced. While the Yeo Johnson transformation, provides the best normality, the Order Norm variable will also perform well.
Data is unable to be distributed by time or geography. The roll up method used is Weighted Average.

Seasonal and Trend Decompostion
Data shows autocorrectation indicating a need for differencing
The ACF indicates 2 order differencing is appropriate.
Further differencing is reccommended
The Kwiatkowski-Phillips-Schmidt-Shin (KPSS) test, KPSS Trend = 0.36 p-value = 0.01 indicates that the data is not stationary.
The Shapiro-Wilk test returned W = 0.89 with a p-value =0.00 indicating the data does not follow a normal distribution.
A skewness score of 0.50 indicates the data are fairly symmetrical.
Hartigan's dip test score of 0.03 with a p-value of 1.00 inidcates the data is unimodal
