Confidence Interval

The estimation accuracy of the sample is quantified by the confidence interval (CI). The confidence interval is calculated in such a way that, in 95% of repeated samples, it would contain the true value. For the calculation of the CI, the R package chensus is used, which implements the formula according to “Structural Survey of the Federal Population Census: Sampling Design and Selection, Weighting, Estimation Method and Pooling 2010–2018 (Chapter 6.2.2)”.

Accuracy

Estimate reliable: 50 or more observations. This is a normally reliable estimate.

Estimate conditionally reliable: 5–49 observations. This is an estimate based on few observations and should be interpreted with particular caution.

No estimate (not reliable): Fewer than 5 observations. The small number of observations does not allow for the publication of the estimate.
