The mean income or median income in a society or group describes the income level from which the number of households (or persons) with lower incomes is the same as that of households with higher incomes. The median thus defines the mean income.
It should be noted that an income can be that of a single person as well as that of several people in a household with a single income ( household income ). An individual is a size 1 household. Each income supports a size 1 or more household.
The median income is the income that is exactly in the middle of the income considered and sorted by size. For example, the second highest would be the median income of three incomes considered, with 101 incomes it would be in 51st position. The average income as the arithmetic mean of all incomes (also: average household income) is usually higher, as the differences between the middle income and the higher and highest incomes are often many times greater than the differences between the lower incomes and a few households are very high Draw income, i.e. the income distribution primarily knows outliers upwards. The per capita income as the arithmetic mean of all incomes in relation to the population is lower because one income provides for more than one person on average.
The mean income must be distinguished from mean wealth .
of the median annual disposable income of households in 34 countries on a dollar basis as of 2010
Situation in Germany
The median of the net income in 2013 was 1,345 euros.
The median of the net equivalent income of the population of Germany was 1,772 euros per month in 2008, in 2013 it was 1,957 euros per month.
The difference to the (arithmetic) net income is that not every household member is weighted equally. For example, when calculating the net equivalent income, a couple without children would only be weighted with a factor of 160% instead of 200% - the second person only needs 60% of the income of the first person for this calculation. As a result, the median of the equivalised income is always higher.
Adjusted for purchasing power on the basis of prices from 2005, the following development of the median of the net earned income of all employees can be determined:
- in 2000 (33.2 million employees) 1,324 euros / month,
- in 2005 (33.4 million employees) 1,300 euros / month,
- in 2010 (35.3 million employees) 1,294 euros / month.
Average hourly wage
The real wage for the 10% with the lowest incomes was a maximum of € 5.03 in 2010 (based on 2005 prices), and for the 10% with the highest income at least € 27.77. (The figures do not take into account trainees or persons in labor market employment measures.) The median real wages in 2010 was € 12.84 (adjusted for purchasing power in 2005 prices). Compared to the comparable figure from 2000, adjusted for purchasing power, this is a decrease of 2.3%, compared to 2005 even a decrease of 4.9%. Adjusted for purchasing power, hourly wages in Germany fell significantly between 2000 and 2010. In particular that of the bottom 30%, namely by 10.6%. Only the real wages of the highest income 10% have increased.
