Thousands of Persons, Seasonally Adjusted
Total nonfarm employees measures the number of persons 16 years of age or older working in nonfarm positions. This indicates population size and occupation opportunity.
The data shows autocorrection and a non-normal distribution. The data should be differenced. While the Untransformed transformation, provides the best normality, the Square Root variable will also perform well.
Data is able to be distributed by time but not by geography. The roll up method used is Sum.

Seasonal and Trend Decompostion
Data shows autocorrectation indicating a need for differencing
The ACF indicates 1 order differencing is appropriate.
Following first order differencing, no further differencing is required based on the differenced ACF at lag one of -0.08
The Kwiatkowski-Phillips-Schmidt-Shin (KPSS) test, KPSS Trend = 0.38 p-value = 0.01 indicates that the data is not stationary.
The Shapiro-Wilk test returned W = 0.94 with a p-value =0.00 indicating the data does not follow a normal distribution.
A skewness score of -0.08 indicates the data are fairly symmetrical.
Hartigan's dip test score of 0.03 with a p-value of 0.96 inidcates the data is unimodal
