Understanding Our Gap

CSO Corporate Report,

Regression Analysis

It is important to consider the factors that might underly the gender pay gap. Regression analysis allows us to explore how certain variables available for analysis such as grade, time in grade, age, employment status (Permanent or Temporary) and employment type (Full-time or Part-time) as well as gender might influence pay. The analysis indicates that over 70% of the variation in pay was explained by grade alone (r2=0.7017). When grade, time in grade, age, employment type and employment status are considered, over 83% of the variation in pay is explained (r2=0.8344). Analysis of variance indicates that gender is not significant in the model (p=0.141), suggesting that there is no strong evidence of a gender pay gap after adjusting for other variables. Employment status is also not significant (p=0.824) in the model. 

Grade Breakdown

Looking at the breakdown of the various CSO grades by gender it is evident that there are more males than females in the grades of Principal Officer, Senior Statistician, Statistician, Assistant Principal and Services Officer. Conversely, there are more females than males in the grades of Higher Executive Officer, Executive Officer, Clerical Officer, and Survey Interviewer. See Figure 5.1

Length of Time in the Grade

The analysis of permanent employee’s length of time in their current grade shows that males are longer in the majority of grades from Assistant Principal and above, Higher Executive Office and Service Officer. Specifically at the grades of Principal Officer, Senior Statistician and higher, this indicates that females are joining these grades more recently. Conversely, females are, on average, longer in the other grades of Statistician, Executive Officer, Clerical Officer and Survey Interviewer. See Figure 5.2

Analysis of Employees who availed of Part-time Working Arrangements

The majority of employees working part-time in the CSO are female and working in the grades of Clerical Officer and Executive Officer. There are less employees in the higher grades availing of part-time working. In this context, part-time employees include those who are working on a reduced weekly work schedule compared to their full-time comparator. It does not include full-time employees who availed of unpaid leave absences such as Parental Leave and Shorter Working Year Scheme during the reporting period. See Figure 5.3 and Figure 5.4

Analysis of Employees who availed of Unpaid Leave

There are a variety of different unpaid leave schemes available to CSO employees. For this analysis, the focus is specifically on Shorter Working Year (SWY) leave and Parental Leave. In general, more females than males availed of these leave schemes (see Figures 5.5 and 5.7) and those that availed of it tend to be in the lower grades (see Figures 5.6 and 5.8).
