According to international standards, the modernization of the production of official statistics is, among other things, the integration of various sources of statistical information, in contrast to the traditional method, often called the stovepipe approach (an isolated approach to operations).
Currently, the sources of statistical information are those of administrative origin, coming from our own surveys or from others and, eventually, the data generated by public or private companies.
The aim of the Integrated Statistical Information System (SIIE) is to make it possible for two or more sources of similar or varied origins to be used in conjunction with one another when required by an official statistical operation. The SIIE was created under the 23/1998 law, on statistics in Catalonia, and we are now developing the 21st century version.
To achieve this goal, in the last few years Idescat has been working on two parallel lines or paths: the technological line (with the construction of the Cerdà Platform) and the statistical process line (with the Qualitas Project).
The Cerdà Platform master plan was approved in July 2014 and its construction began in March 2015. The first statistics (in the tourism area) were published in April 2017; these can be viewed by means of the first version of the platform's data viewer. Also in 2017, the core of the statistical Register of the population was developed and the one on territory was begun. The project remains under development in 2018 with new components, one of which is the API automating users' data downloads.
In order to achieve the integration of the information, the Cerdà Platform has structured the process of the statistical information conceptually in four phases:
As explained in the introduction, the Qualitas Project consists of the description of statistical processes adapted to an integrated information environment. In order to achieve maximum efficiency in statistical production, it is necessary that all the available information works together in describing a complex and changing social and economic reality.
In a first phase, the Qualitas Project has carried out a full and accurate description of the processes in which Idescat is working, using the GSBPM model, as a guide, an international standard developed and adopted by the OECD, Eurostat and the UNECE. The transformation and integration into the Cerdà Platform is being worked on, based on some 70 projects already documented.
The aim of the Qualitas Project is twofold: on the one hand, to use the detailed documentation of the processes to ensure quality (relevance, timeliness, efficiency, accuracy and reliability, coherence and comparability, accessibility and clarity); and on the other hand, to provide a guide and control, at different levels, regarding the following aspects:
