Employment change refers to the change in the number of persons who are in employment, derived by taking the difference in the employment level at the end of the reference period compared with the end of the preceding period. A positive change refers to the additional number of persons who are in employment, while a negative change refers to the decline in number of persons in employment. For example, if total employment in December 2010 and December 2011 are 3,105,900 and 3,228,500 respectively, then the employment change in 2011 is 3,228,500 – 3,105,900 = 122,600. In other words, there were 122,600 more persons in employment in December 2011 than a year ago.
Conceptually, the change in employment over the reference period is the difference between people entering and exiting employment during the period. Users should not mistake an increase in employment as gross job creation.
