Hagenbach-Bischoff system

The Hagenbach -Bischoff method is a method of proportional representation ( seat allocation method ), as described for example in elections to the distribution principle of proportional representation (see proportional representation ) is needed to convert votes into mandates deputies. The Hagenbach -Bischoff method is a Swiss physicist from Eduard Hagenbach - Bischoff (1833-1910) developed algorithm of the D' Hondt method. This type of description of the D' Hondt method is found, inter alia, the Swiss Federal Act on Political Rights ( SR 161.1, article 40Vorlage: Art / Maintenance / ch- search f. ), Which is in the national elections of application. Due to their computational steps, under which any party allocated as quota sampling in the first step seats according to their rounded rate and then the remaining seats are distributed, it is also referred to as quasi- ratio method.

Example

Assumed election result:

To be distributed seats: 10 party votes   A 4160   B 3380   C 2460 Step 1: basic distribution

Distribution score = ( 4160 3380 2460 ) / ( 10 1 ) = 10000/11 = 910 rounded up

( In the case of an integer ratio of the is increased by 1. )

A: 4160/910 rounded down = 4 B: 3380/910 rounded down = 3 C: 2460/910 rounded down = 2 That is, in the first step are 4 3 2 = 9 mandates distributed.

Step 2: Calculation of the maximum numbers for the next seat

A: 4160/5 = 832 B: 3380/4 = 845 (*) C: 2460/3 = 820 The next (last) seat gets Party B.

Distribution: 4 - 4 - 2 see also
