Online methods

To reduce burdens on respondents, the two modern online reporting methods IDEV and .CORE are available. Businesses and authorities can use them to efficiently transmit their statistical data to the statistical offices online via the internet. Both systems and their explanations are available in the German original version.

IDEV stands for internet-based data collection of the statistical offices of the Federation and the Länder and allows form-based input of data and uploading of files. The IDEV Information online reporting method has jointly been developed by the statistical offices of the Federation and the Länder. For further information please refer to our leaflet (pdf, 251KB). The technical requirements are described in our online help.

.CORE stands for »Common Online Rawdata Entry« .CORE and supports automated retrieval of statistical raw data from the internal data available at enterprises and authorities and their transmission to the central online data portal without switches between media. The .CORE online reporting method has been developed by the statistical offices of the Federation and the Länder in co-operation with the Association for economical administration (AWV) and reputable software producers. For further information on .CORE please refer to our leaflet (pdf, 114KB) or to our web site, which contains more details.

Using IDEV and .CORE requires user ID and password.

In the case of IDEV, these are statistics-specific codes which are sent to you for nearly all statistics together with the survey documents. For intra-Community trade statistics, you can register online for that service. If you wish to test IDEV, please use the guest access available for the purpose.

For any data to be transmitted via .CORE, you will get your access information after one-time online registration. You may use that information, irrespective of the statistics, for your enterprise and the local units for which you wish to transmit data.
