The adult smoking rate indicates the proportion of respondents aged 15 and over who answered the questions on smoking behavior in the microcensus and smoke occasionally or regularly. Data for adults are collected quadrennially as part of the Microcensus conducted by the Federal Statistical Office. Intermediate years in the data series were interpolated. The microcensus is the largest household survey in Germany and Europe. The sample survey covers 1 percent of the total population.

The federal government has set a goal of reducing adult smoking rates to 19% by 2030.

For indicators without a set baseline by the German Sustainability Strategy, 2030Watch uses the 2008 baseline of the EU 2020 Strategy.

This is an official indicator of the German Sustainability Strategy.
