5.1. Relevance - User Needs | |||
The NES (National Employment Survey) carried out by the CSO collects information for the SES (Structure of Earnings Survey) and provides the data required under EU Regulation (EC) No. 1738/2005 of the European Parliament and of the Council of 21 October 2005 for the Structure of Earnings Survey (SES), forwarded to Eurostat every 4 years.
The NES Business Survey was carried out annually between 2003 and 2009. In 2010 the NES was produced from administrative data sources as a result of budgetary restrictions. The objective of the NES was to provide, at national level, very detailed structural information on workplace issues, including earnings and factors influencing earnings, which other short-term earnings surveys could not provide. Factors influencing earnings include: occupation, educational attainment, age group, length of service and nationality, as well as other factors that go towards explaining differences in rates of hourly and annual earnings. The NES is also the main source of earnings for the Gender Pay Gap and for Median earnings which are required both at EU and National level on an annual basis. The Irish Government requested the CSO to provide an up-to-date comparison of the earnings of the public and the private sectors. In Ireland, as in other EU-Member States the comparison of the earnings of the public sector and the private sector has been for use in discussions on public sector wage levels. Data sources are central to undertaking any analysis. In Ireland, the CSO’s NES, was identified as an appropriate source for undertaking the comparison of the earnings of the public sector and the private sector, see Foley & O’Callaghan[1] and Kelly et al [2].
The main users of the NES survey are the following:
User Needs The main user needs are a breakdown of average earnings in the main Classifications e.g. NACE, Occupation etc; Median earnings and Gender Pay Gap requirements. Researchers main needs are analysis of the Research Microdata files (RMFs) for macroeconomic research. Extensive research has been published from the NES RMFs on Gender; Nationality; Public/Private Wage Gap; Earnings levels in the economy; etc.

5.2. Relevance - User Satisfaction | |||
Researchers are assisted with infrastructural support to work on the RMFs. The staff team in the Earnings Analysis Section liaise with the researchers and provide technical support. Researchers are very satisfied with the level of support and a large body of research has been carried out by researchers involved in policy issues and macroeconomic research. Most researchers renew their access to the RMFs on an annual basis. |

Difference between the Reference and Study Population The SES 2010 was constructed from Administrative data sources, namely the NES 2009 and Revenue 2009 and 2010 Annual Earnings trends. For accuracy of earnings trends the SES 2010 did not include employees working less than 10 hours per week nor less than 50 weeks in the year. This cohort of employees was considered too volatile to monitor trends in income changes between 2009 and 2010. This has resulted in under-representation of employees in Sectors which have a high proportion of part-time and casual staff (e.g. Food & Accommodation Services, Retail, etc.). The enterprises in the SES 2010 only include those with 3 or more employees. Therefore some sectors such as Professional Services (e.g. Doctors, Solicitors, etc.) may be under represented as there is a high proportion of sole traders and private practices in these sectors. |

SES 2010 The NES 2009 survey was used to construct the SES 2010 data by applying Revenue Commissioners income changes to the NES 2009 data. An analysis of employees’ net incomes from Revenue Commissioners data was carried out to calculate the percentage change in incomes between 2009 and 2010. This percentage change was then applied to the 2009 NES data to create the NES 2010 data. Therefore the NES 2010 hours worked are unchanged from the 2009 NES data, but the earnings have been adjusted to follow Revenue Commissioners income trends. The standard approach for comparisons is to match the data for employees who work for 10 or more hours per week and work for 50 or more weeks per year. Also employees whose Revenue Commissioners net income in 2010 were outside a 40% range of their 2009 Revenue Commissioners net income were excluded; as large changes in Net incomes may be the result of pension contributions varying from year to year. This is the criteria under which the SES 2010 data is analysed. Short-term earnings statistics showed that hours worked remained relatively unchanged between 2009 and 2010. |

(1) Employee Numbers Coherence with the structure of employees in the QNHS (Quarterly National Household Survey – the labour force survey) for the same reference period The QNHS includes all employees in the state while the SES includes only those with greater than 3 employees. This is most evident in economic sectors where there are a large proportion of small businesses such as in Retail, Hotels & Restaurants and the Construction industry. The breakdown into full-time and part-time employment proved problematic in that employers may have stated that the employee was working full-time hours but the employee classified themselves as part time. The NES is calibrated with the QNHS to take account of these factors. However the SES 2010 excludes those working less than 10 hours per week and less than 50 weeks in the year as outlined above.
Employees in SES 2010 in comparison to QNHS
Footnote * Employees in the SES 2010 only include the following: Employees worked 10 or more hours per week Employees worked 50 or more weeks per year $ Includes NACE Sectors R to U
(1) Gross Annual Earnings The values for gross annual earnings in the SES 2010 only include employees working 50 or more weeks per year and 10 or more hours per week. The individual employee gross annual earnings are grossed up to the enterprise and then grossed up to the NACE sector. This differs from the EHECS (Earnings Hours and Employment Costs Survey) where the average annual earnings is calculated by dividing the wage costs for the enterprise by the number of employees and grossing this figure up to the NACE Sector to get the quarterly earnings; the average of the four quarterly earnings are then used to compile the average annual earnings.
