Why Use This Data Source In Your Models?
Total manufacturing employees measures the number of persons 16 years of age or older working in manufacturing positions. This indicates population size and occupation opportunity.

Thousands of persons, Not Seasonally Adjusted
The data shows auto correlation, seasonality and a non-normal distribution. The data should be differenced and seasonally adjusted. While the Square Root transformation, provides the best normality, the Arcsin variable will also perform well.
Data is able to be distributed by time but not by geography. The roll up method used is Sum.
Data shows auto correlation indicating a need for differencing
The ACF indicates 1 order differencing is appropriate.
Further differencing is reccommended
The Kwiatkowski-Phillips-Schmidt-Shin (KPSS) test, KPSS Trend = 0.14 p-value = 0.06 indicates that the data is stationary.
The Shapiro-Wilk test returned W = 0.97 with a p-value =0.01 indicating the data does not follow a normal distribution.
A skewness score of 0.16 indicates the data are fairly symmetrical.
Hartigan's dip test score of 0.05 with a p-value of 0.16 inidcates the data is unimodal
