TURNOVER IN SERVICES
n The Turnover in services index measures the quarterly evolution of sales by service sector enterprises at
current prices. Since the first quarter 2018 indices are calculated with reference to the base year 2015
using the Ateco 2007 classification (Italian edition of NACE Rev.2).
n In the third quarter of 2022 the seasonally adjusted Services turnover index increased by 2.2% compared
to the previous quarter. In particular the index increased in Accommodation and food service activities
(+5.4%), in Transportation and storage (+3.9%), in Information and communication (+2.1%), in Wholesale
trade, trade and repair of motor vehicles and motorcycles (+1.7%), in Professional, scientific and technical
activities (+1.6%) and in Administrative and support service activities (+1.3%).
n In the third quarter of 2022 the Services turnover index increased by 12.4% compared to the third quarter
2021. In particular, the index increased by 20.9% for Accommodation and food service activities, by 19.9%
for Transportation and storage, by 11.9% for Administrative and support service activities, by 10.8% for
Wholesale trade, trade and repair of motor vehicles and motorcycles, by 7.3% for Professional, scientific
and technical activities and by 6.6% for Information and communication activities.

Calendar adjusted data: working day adjusted data refer to the correction for calendar effect in a reference period
(month or quarter) that may vary from year to year. The calendar effect is the variation caused by the changing
number of particular week days or holidays in different months or other time periods (quarters, years). Calendar
adjustment is mainly used in the calculation of short-term statistics (STS), for converting gross (unadjusted) figures
or indices into their calendar adjusted equivalent. In order to adjust a figure or an index. the calendar nature of a
given month or quarter is taken into account and calendar effects are removed. whatever their nature. The calendar
effect may for example depend on i) the timing of certain public holidays (Easter can fall in March or in April,
depending on the year); ii) the possible overlap of certain public holidays and non-working days (1 May can fall on
a Sunday); iii) the occurrence of a leap year.
Economic activity sectors: economic activity sectors defined according to the Ateco 2007 Italian classification of
economic activities derived by the NACE Rev.2 classification.
Seasonally adjusted data: seasonally adjusted data refer to the statistical technique designed to remove
fluctuations related to seasonal factors (such as weather conditions, administrative measures, etc.) and calendar
effects when relevant. Seasonal adjustment provides a clearer view for a trend analysis of a short-term index.
Services turnover index: services turnover index measures the quarterly changes of services sales at current
prices.

Introduction and regulatory framework
The quarterly services turnover survey is aimed at producing short-term indicators useful for measuring the
performance of the value of goods and services sold by businesses belonging to the services economic activity
sectors. These indicators provide. for the sectors they refer to. information about the dynamic of the value of the
sales. which incorporates the variations both in volumes and prices. The methodology. the breakdown and the
frequency of releases are defined by European Regulation on Short-Term Statistics (Regulation No. 1158/05 of the
European Parliament and of the Council).
The legal basis for the STS indicators are the Regulation (EU) 2019/2152 of the European Parliament and of the
Council on European business statistics, repealing 10 legal acts in the field of business statistics (EBS-Regulation)
and the Commission Implementing Regulation 2020/1197 laying down technical specifications and arrangements
pursuant to Regulation (EU) 2019/2152 (General Implementing Act).
The survey is included in the Italian National Statistical Programme. It is a sample survey. the unit of observation is
the enterprise. variables of interest are turnover and average number of persons employed by the economic unit in
the reference quarter. The definition adopted for the turnover is shown in the Commission Regulation (EC)
N 1503/2006 and is consistent with the legislation on the drafting of financial statements in Italy. The list of the
economic units belonging to the population of reference used for selecting the sample. is represented by the
Business Register (Statistical register of active enterprises – Asia).
Indicators and weighting structures
Istat produces and disseminates the quarterly turnover indicators on services sector as index numbers having 2015
as base year. These indices are aggregated according to the Laspeyres formula, using a weighting structure based
on the distribution of the turnover in the services sector. The general services turnover index. according to the
Regulation, does not include retail sales (but it includes retail sales of vehicles and motorcycles).

Sampling design
The calculation of the turnover indices is based on the information collected through a quarterly survey which
involves a representative sample of enterprises belonging to the services economic activity sectors.
Stratification
The sampled economic units are selected from the most recent available Business Register (usually updated at
year t-2) and are provided with an information letter.
Sampling units are selected according to two different approaches. For the economic activity sectors with a high
number of businesses, stratified simple random sampling designs are preferred, In sectors in which few large
businesses determine the market dynamic (50 – Maritime and water transport, 51 – Air transport, 53 – Postal
services and courier activities, 61 – Telecommunications and 78 – Research, selection and supply of personnel).
cut-off type sampling schemes of unit selection are adopted. The largest businesses in terms of number of persons
employed and turnover are selected. up to covering a sufficiently high amount (usually greater than 80%) of the
total turnover of the sector. For the remaining sectors. appropriate thresholds are detected based on number of
persons employed and then enterprises are selected from the subpopulations identified.
In general, a threshold of 2 persons employed is defined. The exceptions are represented by the economic activity
sectors characterised by a greater prevalence of medium-large businesses (45.1 – Vehicle sales, 49.1 – Railway
passenger transport, 49.2 – Railway freight transport, 52 – Storage and transport support activity). for which the
threshold value is fixed at 5 persons employed. and the group of Sales agents (46.1) for which no threshold is
used. For the sectors distinguished by the presence of medium-small companies, a stratified simple random
sampling design is chosen using, as stratification variables, the economic activity (at group level 3 digits of the
NACE Rev.2 classification) and business size (in terms of persons employed: from 2 to 5, from 5 to 20 and from 20
to 100 persons employed, excluding the right limit for each size class). The businesses with a number of persons
employed equal to or greater than 100 represent the self-representative stratum.
For the sectors of Professional. scientific and technical activities (section M) and of Tourism agencies and business
support services (section N), the rules followed are different. For the sectors characterised by a considerable
number of small-sized businesses (69 – Legal and accounting activities, 70.2 – Management consulting activity, 71 –
Architecture and engineering study activities, inspections and technical analyses, 74 – Other professional. scientific
and technical activities) no threshold is provided for the number of employees. The sample units are selected by
the sub-population of enterprises with annual turnover exceeding 50.000 Euros. For the activities of services of
tourism agencies, tour operators and booking services and connected activities (division 79) the value of the
threshold is 2 persons employed, for Advertising and market research (division 73) the value is 5 persons
employed, and for Vigilance and investigation services (division 80) that value is 20 persons employed. In general.
the persons employed size classes are defined as follows: from 1 to 2 persons employed, from 2 to 5, from 5 to 10,
from 20 to 50, from 50 to 100 persons employed excluding the right limit for each size class. For Cleaning and
extermination activities (group 81.2) a further size class has been used. from 100 to 250 persons employed. and
the businesses with a number of persons employed equal to or greater than 250 constitute the auto-representative
stratum. For the remaining sectors, the auto-representative stratum is that with a number of persons employed
equal to or greater than 100.
Estimation domains
The stratification criteria adopted, in addition to defining homogeneity within each stratum. allow a better definition
of the estimation domains.
Estimation domains are defined, for the majority of the sectors. according to the economic activity groups. For the
Professional, scientific and technical activities sectors (section M) and Travel agencies and business support
services (section N) the estimation domains correspond to the two digits of the NACE Rev.2 classification. Since
their characteristics, an extension to 4 digits was considered for the classes 49.31 (Road passenger transport in
urban and suburban areas). 49.41 (Road freight transport). 52.21 (Services connected with ground transports) and
52.29 (Other support activities connected with transports). For the Air transport, a single domain is defined, and the
sample businesses cover approximately 95% of the total turnover of the sector.

The sample allocation within each stratum was carried out using the Mauss-R software which incorporates a
generalized procedure developed at Istat. based on the Neyman allocation method for the multivariate case,
following a generalization proposed by Bethel (1989)1. The sample size for year 2021 survey is reported in table 4.

Estimation methodology
The estimation of the indices at domains of interest level follows two methodological approaches: for some
economic activity sectors, indices are obtained as the result of the variation of the turnover of the economic units
respondent both to the reference quarter and to the same quarter of the previous year. For remaining sectors,
estimation of the quarterly turnover levels is obtained through the calibration estimators 2 approach and then indices
are calculated as the result of the variation of the turnover. In particular, the latter approach is used for the
Commercial divisions and vehicle and motorcycle repair, Land transport and transport via pipeline, Storage and
transport support activities, Hospitality and restaurant services activities and for the section of Professional,
scientific and technical activities and Travel agencies, company support services (with the exception of the division
of Research. selection and supply of personnel activities). The initial sampling weights are obtained for each
stratum as the ratio between the number economic units of the reference population (Business Register) and the
number of the sampled economic units.
In order to take into account the effect of unit non-responses, the calibration estimators methodology was used
(ReGenesees software – R Evolved Generalized Software for Sampling Estimates and Errors in Surveys). The
calibration method exploits the information provided by auxiliary variables (turnover and/or employees of the most
recent Business Register) highly correlated with the variable of interest.

The indices calculated at the single domain level are then aggregated through a weighting system (referring to
base year 2015) derived from the estimates of turnover obtained in the context of the statistics on “The economic
performances of Italian enterprises” up to the level of the economic class (fourth digit of the NACE Rev.2
classification).
Reconstruction of the general index
On the occasion of the release of 27 May 2015, the seasonally adjusted series of the general services turnover
index was disseminated. In particular, the indices of the groups of Sale of motor vehicles, Sale of motor vehicle
parts and accessories, Sale, maintenance and repair of motorcycles and related parts and accessories and of the
divisions of Land transport and transport via pipelines, Warehousing and support activities for transportation,
Accommodation and food service activities are issued starting from the press release of 30 May 2012, while the
indices for the divisions of the sections of Professional, scientific and technical activities and Administrative and
support services activities were disseminated starting from the press release of 5 June 2014.
The reconstruction of the time series was carried out using the information coming from the quarterly production at
current prices of the National Accounts at different levels of aggregation of the product classification (CPA) and the
economic activities (NACE Rev.2). In particular, the indices before 2010 were calculated using the year on year
dynamic of the series of the National Accounts. In this way it was possible to have series starting from the first
quarter of 2001 for aggregations of classes/divisions of economic activities listed in Table 5.

Using the fixed weights structure, which reflects the sector distribution of the service turnover in 2010, it was,
therefore, possible to calculate both the series of the indices for the divisions of economic activity and the series of
the general services turnover index.
The seasonally adjusted series and revisions
Starting from the release of 25 November 2016. the dissemination of the seasonally adjusted indices was extended
in order to complete the coverage of the general index of services turnover (FAS). For this purpose, the level of
detail defined by the previously disseminated series has been taken into account: Vehicle maintenance and repair
(G452), Wholesale trade (G46), Maritime and waterway freight transport (50), Air Transport (H51), Postal services
and courier activities (H53), Information and communications services (J). The aggregated series in which the
elementary indices are available in seasonally adjusted form starting from the second quarter of 2016 (Trade and
repair of vehicles and motorcycles – G45, Wholesale and retail trade and repair of motor vehicles and motorcycles –
G. Transportation and storage – H. Turnover in services – FAS), were seasonally adjusted with the indirect method,
that is aggregating the seasonally adjusted elementary series with the weights shown in the table 6.

** Division G 47 is not included.
The seasonally adjusted elementary indices are obtained through the TRAMO-SEATS+ procedure. Like other
seasonal adjustment procedures, TRAMO-SEATS+ is based on the hypothesis that a quarterly time series can be
represented as a combination of different components that are not directly observable (trend-cycles. seasonal
trends. irregular components). In particular, TRAMO-SEATS+ identifies a representative statistical model of the
time series (model-based approach), thanks to which it is possible to identify and eliminate the seasonal
component. Since the addition of new quarterly information allows a better evaluation of the different components
of the series, each quarter the previously published data concerning the most recent years is subject to revision.
To allow users to analyse the seasonally adjusted time series. the specifications adopted by Istat in the context of
the TRAMO-SEATS+ procedure are available upon request.
Geographic breakdown
The data are available at a national level.
Timeliness and issue
The dissemination of the quarterly services turnover indices is made via a press release, in a provisional version
which is released within 60 days from the end of the reference quarter. Final data are provided within 150 days by
the end of the reference quarter.
The press releases are available on the Istat web site.
The indicators are also available on I.Stat. the Istat data warehouse. within the section Services?Turnover? Index
of turnover in other services. The most recent monthly series relating to the turnover in services indices are
available on the web page of the press release. in the excel file “time series”.

Measures adopted to handle the impact of pandemic emergency on the survey
The COVID-19 pandemic emergency did not affect the data collection for businesses involved in this survey.
Overall, the majority of them provided the information required. With reference to the seasonallyadjustment
procedure used to treat the indicators disseminated, the seasonal adjustment models were reviewed to manage the
exceptional changes recorded since first quarter 2020 taking into consideration the Eurostat guidelines, available at
the URL:
Therefore, since the first quarter 2020, the unusual size of the changes of the unadjusted time series were taken
into account. For this purpose, additional regressors (the so-called additive outliers) were introduced in models for
seasonal adjustment when statistically significant. This procedure, which aims at minimizing the revisions of past
values of the seasonally adjusted series, was maintained also in the third quarter 2022. As soon as the available
information will allow an overall evaluation of the great volatility phase, models will be revised/modified if necessary.
In that case, revisions of seasonally adjusted data may be larger than usual.
