To answer this question would require earnings information for individual employees, which is not collected as part of this survey.

The primary aim of the Index of Average Earnings is to measure the change in overall average earnings. The methodology is therefore designed to calculate mean averages, and does not provide a full earnings distribution of individuals.

The dataset used to compile the Index of Average Earnings comes from a survey of employers rather than a survey of individuals. Businesses report aggregate numbers; total gross wages and salaries paid to employees and the total number of staff covered by those earnings. This enables mean average earnings to be calculated for each company, sector and overall as well as the associated percentage changes. It is not possible to produce analysis relating to individuals or individual earnings distributions from the data collected by this survey.

In general terms, earnings distributions tend to be asymmetric (ie skewed towards higher values). In a ‘normal’ distribution (ie not skewed) one would expect the mean and the median (the middle value of the distribution) to be the same value, in which case 50% of individuals would fall below the mean value. For a skewed distribution such as earnings, it can therefore be inferred that more than 50% of individuals would earn less than the mean value.

The States of Jersey Statistics Unit ran a Household Income Distribution Survey (IDS) in 2014 to 2015, the results of which are due to be published later this year. The IDS is a survey of households (rather than individuals) and covers earned as well as unearned income. It will provide further information on the overall income distribution for Jersey at household level.

The average earnings figure of £900 per week in the public sector is calculated on the basis of a full-time equivalent (FTE) worker. Earnings are gross (ie before deductions for income tax and social security) and include overtime payments, but exclude employers’ insurance contributions, holiday pay and benefits in kind (eg free accommodation or meals). Part-time employees are weighted in the calculation of FTEs according to hours worked.

Employing the same methodology, 3,221 employees would attain the £900 per week if their salaries were expressed as a full-time equivalent. This represents 41.5% of the total of 7,761 employees paid in June which includes full-time, part-time and zero hours workers.
