Title: Nutzung von Informations- und Kommunikationstechnologien in Unternehmen 2019

Organisation running the survey: Statistisches Bundesamt

Survey period:

March  2019 - 10 July 2019

For both surveys: 10+ and <10 p.e.

Sampling and statistical methodology:

The sampling was undertaken in December 2018. The time lag regarding administrative variables was corrected for - if necessary - by information from the business register in January 2019.The same frame is used for sampling and grossing up in the ICT survey.

 

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 1548.

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.)

No coordination with samples of other surveys took place.

Reference period: according to model questionnaire

Collection method: It is a combination of a self-administered mail and a web survey – respondents can either choose. The web-questionnaire is provided barrier-free. Stand alone and voluntary survey.

Population covered: NACE Rev. 2 sections C, D, E, F, G, H, I, J, L and N, divisions 69-74, 77-82 and 95.1.

Enterprises with less than 10 persons employed were also covered. Whole country covered.

Population size: 2.807.347 enterprises (whereof  2.459.125 less than 10 pers. employed)

Sample size : 61.933 enterprises (whereof  24.443 less than 10 pers. employed)

Organisation running the survey: Statistisches Bundesamt

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%.

Reference period: according to model questionnaire

Overall response rate:  49,66% (10+); 35,39% (<10)

Main methodological differences compared to previous survey(s): 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.

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%.

(Size class 1 to 4 persons employed in table 5.3 and table 6.2 includes enterprises of the „0”-stratum; for the exact number of enterprises in the „0”-stratum please see annex)

Reference period: Year 2007 for the % of sales/orders data and where specified, January 2008 for other data

Country: Germany

Year: 2006

Title: Nutzung von Informations- und Kommunikationstechnologien in Unternehmen 2006

Organisation running the survey: Statistisches Bundesamt

Survey period: End of February - end of May 2006

Sampling and statistical methodology:

The sampling base of the survey is the active enterprise register

 

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”.

On the second stage the optimal allocation by Neyman-Tschuprow was applied concerning the variable employees in each stratum (Land x NACE categories).

Reference period: Year 2005 for the % of sales/orders data and where specified, January 2006 for other data

Collection method:

Mail survey; stand alone survey; voluntary survey.

Population covered: NACE sections: D, E, F, G, H [55.3-55.5], I, J, K, 92 [92.3-92.7], 93, 67.12, 67.13, 67.2

Enterprises with 10 or more persons employed. Enterprises with less than 10 persons employed are also included.

 

Population size: 1.980.495 enterprises

Sample size 20.245

Overall response rate: 52.55%

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.
