Survey period: March 2021 - 10.07.2021 For both surveys: 10+ and <10 p.e. |
Sampling and statistical methodology: The sampling was undertaken in December 2020. The time lag regarding administrative variables was corrected for - if necessary - by information from the business register in January 2021. The same frame is used for sampling and grossing up in the ICT survey. The frame population of the ICT usage and e-commerce survey is not coordinated with other statistic, incl. the SBS.
Stratification: For sampling a random stratified sample was used. The variables of stratification were the federal state, the economic activity (according to NACE Rev. 2) and the number of employees (including a „0”-stratum, see annex for further information). The final number of strata amounted to 1555. The sample of enterprises is selected using a stratified random sampling method. Enterprises are grouped into strata taking into account "Federal state", "economic activity" and size classes of employees. The allocation of sample size to strata is following the optimum allocation (minimizing variance for a fixed cost) in compliance to the quality requirements. At the end, the sample is reweighted by a calibration approach using updated survey and business register information. For the „0”-stratum in each stratum of the sample (federal state x economic activity) a certain number of enterprises from the “0”-stratum was selected. For most cases this corresponded to an inclusion probability of less than 1%. (Size class 0 to 1 persons employed in table 3.1.A2 and C includes enterprises of the „0”-stratum; for the exact number of enterprises in the „0”-stratum, see annex.) |
|
Reference period: The reference period corresponds to the one in the model questionnaire: January 2021. For certain variables (sales, turnover, employees) the reference period was 2020. |
|
|
Collection method: It is a combination of a self-administered mail and a web survey - respondents can choose either. The web-questionnaire is provided barrier-free. Stand alone and voluntary survey. |
|
|

Survey period: March – 20.7.2009 |
Sampling and statistical methodology: In previous years the German business register was used as sampling base whereas for grossing-up the results of SBS were used. To harmonize sampling and grossing-up base, to facilitate national regional comparisons and since no data acc. NACE rev 2 is available from the SBS for the current year, from this year on the business register will also serve as base for weighting the results.
Stratification: For sampling a two-stage stratified random sample was used. The variables of stratification were the Federal State, the NACE-category and the number of employees (including a „0”-stratum, see separately attached file for further information). The final number of strata amounted to 2.160. It was made sure that all strata acc NACE rev 1.1 also consist of a sufficient number of enterprises to allow adequate double report in 2009. At first stage the total sample size was allocated to the variables Federal State and NACE-category using the “Methode der vergleichbaren Präzision”. At second stage the optimal allocation by Neyman-Tschuprow was applied for the variable number of employees in each stratum (Federal State x NACE-category). For the „0”-stratum in each stratum of the sample (Federal State x NACE) a certain number of enterprises from the 0 stratum was chosen. For most cases this corresponded to an inclusion probability of less than 1%. |

Survey period: March – End June 2008 |
Sampling and statistical methodology: The sampling base for the ICT enterprise survey is the business register. For grossing-up the latest available data from Structural Business Statistics is used. Stratification: For sampling a two-stage stratified random sample was used. The variables of stratification were the Federal State, the NACE-category and the number of employees (including a „0”-stratum, see separately attached file for further information). The final number of strata amounted to 1,260. At first stage the total sample size was allocated to the variables Federal State and NACE-category using the “Methode der vergleichbaren Präzision”. At second stage the optimal allocation by Neyman-Tschuprow was applied for the variable number of employees in each stratum (Federal State x NACE-category). For the „0”-stratum a fixed number of enterprises per stratum (Federal State x NACE-category) was chosen. For most cases this corresponded to an inclusion probability of less than 1%.

Stratification: Germany used a two-stage stratified random sample. The stratified variables were federal states (first stage), economic activities (NACE) and number of employees (second stage). The final number of strata was 1320. On the first stage there was an allocation of the total sample size between “Länder” and NACE categories by “Methode der vergleichbaren Präzision”.

Main methodological differences compared to previous survey(s): The new national regulation of Information Society Statistics impacts that we had to reduce the sample size from 40,000 units from the previous year to 20,000 units this year. Germany could not embed the variable turnover in the questionnaire. We have to use this information from our business register. See also Summary methodology 4. – Footnotes |
