The Shonai Town Council will also discuss ways to reduce the number of members and increase the number of members, and will put together measures by June next year.
On the 13th, the Shonai Town Council, which is working to solve the shortage of members, has come up with a new initiative to let residents experience the assembly ... → Continue reading

Number of members
Number of members(Ginteisuu) is the number of members of the Diet when there are no vacancies.MemberIt is the upper limit of the number of people.The number of members does not always match the number of members because there will be vacancies due to retirement or death after the election.The upper limit is the maximum number of people stipulated by law.
ConstituencyThe number of members elected from the constituency is the number of members elected from the constituency.Also called simply a constant.
Constant allocation
Allocate a fixed number of members to each regionConstant allocationIt's called (Constant).Singleseat constituency systemIn the case of, the constant is set to 1, so the question is where and how many constituencies should be set up.OldMiddleelection systemSuch asLarge constituency systemThen, the question of how to set up constituencies and the question of how much fixed number should be allocated to each constituency are mixed.
The same number may be distributed to each constituency (United States SenateIn many cases, the allocation in each state) is proportional to the population.Even in the latter case, it may be adjusted depending on political considerations.In addition, the allocation often does not change even if the population changes.
One vote disparity
In dealing with political issues that will not eliminate the vulnerable and the minority opinions will not be erasedNational election(Japan;House of Representatives general election,House of Councilors ordinary election), There are various debates about what is appropriate for the number of members of the constituency.
It is considered that the number of members in each constituency should be appropriate for the population or the number of voters in the constituency.For example, if you need to make a definite judgment on a twochoice political issue, set the number of members in each constituency to 1.Singleseat constituency systemIn the case of adopting, it is considered appropriate to divide the number of voters into the average population or the number of voters per constituency divided by the number of MPs.However, in reality, voting work is carried out on the scale of municipalities, and it is difficult to bring all constituencies close to the average population or the number of voters.In constituencies with a large population or voter, the value of one vote is light, and in constituencies with a small number of voters, the value of one vote is heavy.Furthermore, it has been pointed out that even if a certain limit is exceeded or a "reversal phenomenon" occurs due to the adoption of the "oneperson quota system", it is against the equality of voters.
Proportional constant distribution method
There are cases where the total constant is determined first, and there are cases where the total constant is determined as a result of determining the constant in each area.The following is the case where the total constant is determined first.
Some of the methods listed belowProportional representationSome are also used to distribute the number of winners of each party.
 Divide the population of the area by a number X and first determine the integer part of the quotient.Next, add one by one in order from the area with the largest decimal part of the quotient, and continue until the total constant is reached. For X, the population per member, that is, the value of total population ÷ total constant is used (called Hamilton's formula).It has been used in the past in the United States.
 Areas of any size do not benefit, they are proportional allocations.
 However, because it is a coincidence of numbersAlabama paradoxThere is a big problem of producing.
 Divide the population of each area by a number X, truncate the quotient after the decimal point, and find an X whose sum is equal to the total constant.Specifically, divide the population of each area by 1, 2, 3, 4, ... in order, distribute in descending order of the number obtained, and continue until the total constant is reached.Also known as the Jefferson style.It has been used in the past in the United States.
 Areas with a large population will benefit significantly.
 Divide the population of each area by a number X and round off the decimal point of the quotient to find an X whose sum is equal to the total constant.Specifically, the population of each area is divided by 0.5, 1.5, 2.5, 3.5, ... in order (the same is true even if divided by 1, 3, 5, 7, ...), and the population is distributed in descending order of the number obtained. And continue until the total constant is reached.Also known as Santo Rage type or Webster type.It has been used in the past in the United States.
 Areas with a slightly smaller population benefit, but are generally close to proportional.
 Adams style
 Divide the population of each area by a number X, round up the decimal point of the quotient, and find an X whose sum is equal to the total constant.Specifically, divide the population of each area by 1 / ∞, 1, 2, 3, ... in order, distribute in descending order of the number obtained, and continue until the total constant is reached.There will always be one or more allocations to all areas.The same result can be obtained by first allocating 1 and then allocating the rest by the D'Hondt formula.
 Areas with a small population benefit.On the other hand, the maximum / minimum disparity in the population per member is small.
 Huntington type
 Set a fixed number for each area so that the relative difference (ratio) of the population per seat does not decrease even if one seat is moved from one area to another.Specifically, the geometric mean, ie 1 / ∞, 1, 1, 1.414, ...Divide by ..., and distribute in descending order of the number obtained and continue until the total constant is reached.Also known as Hill equation or equal ratio equation.There will always be one or more allocations to all areas.United States House of RepresentativesIt is used for distribution to each state.
 Areas with a small population benefit.It is sometimes said that the larger one is profitable (Shigeki Nishihira), but he overlooked the fact that he had to allocate 1 first.
 Dean style
 Find an X whose population per member is as close as possible to a certain number X.Specifically, the harmonic mean, ie 1 / ∞, 1, 1.333, 2.400, ...Divide by ..., and distribute in descending order of the number obtained and continue until the total constant is reached.There will always be one or more allocations to all areas.
 Areas with a small population benefit.

Problem of reducing the number of MPs in Japan
In Japan, the activities required and the required number of members of the national, prefectural, and municipal governmentsAnnual fee(Member compensation)balance of(cost) Is often regarded as a problem^{[3]}^{[4]}..There are some personal opinions that the calculation of rational parliamentary compensation should be based on the number of votes obtained.^{[5]}.Ritsumeikan UniversityAssociate ProfessorMasato KamikuboHe pointed out that the number of parliamentarians in Japan is not large compared to other developed countries, and said, "It is clear that'bureaucratic control'will be strengthened if the number of parliamentarians is further reduced."^{[6]}.

Japanese House of Representatives singleseat constituency
 One seat is first allocated to each prefecture, and the rest is allocated by the maximum remainder method (oneperson quota method).There are criticisms because prefectures with a small population are extremely profitable.Supreme CourtJudged that the elections for members of the House of Representatives in 2009 and 2012 were unconstitutional, and demanded the abolition of the oneperson quota system.
