Dependency ratio

The old age dependency ratio is a term used in demographics. He gives the ratio of the number of older people to the number of younger people in a society.

Extensively used synonymously with the term " dependency ratio ", the terms " dependency ratio " or " old-age dependency ratio " are used.

Calculation of elderly dependency ratio

The old age dependency ratio is the statistical ratio of people (mostly aged 65 and 60 years respectively ) are no longer of working age to those of working age (usually over 15 or 20 years to 64 and 59 years).

He always refers to a specific population at a specific time. It is customary to calculate a dependency ratio of the number of persons aged 65 years in terms of number of 15 - to 64 -year-olds (ie based on the number of persons in the typical working age ). However, a different choice of age limits is also possible. The limits used should be made accordingly always recognizable.

The calculated dependency ratio can be specified as a decimal number with decimal places (for example, by specifying a dependency ratio 0.20 at a ratio of 1 to 5). Usual is a multiplication of the value by a factor of 100 ( in the example, would according to the old age dependency ratio 20 within the meaning of 20 elders result per 100 younger).

More often, there is also an indication as a percentage. This is wrong, however, strictly speaking, and should be avoided, since the dependency ratio always describes a ratio, or a size ratio of two different populations. Percentages detect contrast, usually a part of a whole.

Current Data

2005, the AQ was in Germany at about 32, while he was still in 1957 at 17.

The Commission on Sustainable Financing of social security systems, chaired by Professor Bert Rürup estimated this factor to the year 2000 with 24.2, to the year 2030 and 34.9 in 2040 to 52.6.

The Federal Statistical Office predicted in 2006 for the year 2030 an AQ of 50 or 52, in 2050 he should be 60 or 64.

From the 2011 report published by the Federal Statistical Office, entitled How children live in Germany? shows that no country in the European Union so few children live as in the Federal Republic; as only 16.5 percent of over 81 million German citizens are younger than 18 years.
