Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.

Response Rate
100%.
Actions to speed up or increase the rate of response
Not applicable, since the response rate is normally 100% for the first delivery
14.1. Timeliness
This indicator is released 45 days after the end of the reference period. The monthly data is considered to be definitive one year after the end of the calendar year in which the reference month falls. Revisions are made to the two previous periods.
14.2. Punctuality
STS deadlines have been respected.
15.1. Comparability - geographical
Due to harmonized STS indices in the European Union, it is possible to compare calculated Portuguese aggregates with those of other European countries. There is no regional desegregation, but all national territory is covered, including the AR’s (Azores and Madeira).
15.2. Comparability - over time
To ensure comparability over time, it is tried to keep the data base as steady as possible. STS indices are compared over time (previous month and year). Base 2021 series have been back casted until 2005. Base 2010 have been back casted also until 2005. Base 2005 series have been back casted until 2000.
15.3. Coherence - cross domain
Cross-checks with absolute STS-values (previous month and year). At the first release moment no other data is available for comparisons. At the end of each year an annual trend is compared with the trend of the administrative source IES/SBS. 3 months after the release period comparisons with an administrative source – Social Security - for 2 digits level NACE Rev 2 (confidential data). Trade Statistics are the source of the sample.
15.4. Coherence - internal
Not applicable.
Cost and burden can only be measured for the whole variables 120,121,122 210, 220 and 230. Cost remain 4907 (this measurement wasn´t updated) and burden 28,5 minutes evaluated by inquiry made on 2016.
