The '''Sainte-Laguë method''' ({{IPA-fr|sɛ̃t.la.ɡy}}) is a [[highest averages method|highest quotient method]] for allocating seats in [[party-list proportional representation]] used in many [[voting systems]]. It is named after the French mathematician [[André Sainte-Laguë]]. The Sainte-Laguë method is quite similar to the [[D'Hondt method]], but uses different divisors. In most cases the [[largest remainder method]] delivers almost identical results. The D'Hondt method gives similar results too, but favors larger parties compared to the Sainte-Laguë method.<ref name="lijphart">{{citation|contribution=Degrees of proportionality of proportional representation formulas|first=Arend|last=Lijphart|authorlink=Arend Lijphart|pages=170–179|title=Electoral Laws and Their Political Consequences|volume=1|series=Agathon series on representation|editor1-first=Bernard|editor1-last=Grofman|editor2-first=Arend|editor2-last=Lijphart|publisher=Algora Publishing|year=2003|isbn=9780875862675}}. See in particular the section "Sainte-Lague", [http://books.google.com/books?id=o1dqas0m8kIC&pg=PA174 pp. 174–175].</ref>
 
The Sainte-Laguë method is used in [[Iraq]], [[New Zealand]], [[Norway]], [[Sweden]], [[Bosnia and Herzegovina]], [[Latvia]], [[Kosovo]], [[Denmark]] (for the [[Folketing#Constitutional_requirements|40 supplementary seats in the national parliament]]), and [[Germany]] (on federal level for the [[Bundestag]], on state level for the [[legislature]]s of [[Landtag of Baden-Württemberg|Baden-Württemberg]], [[Elections in Hamburg|Hamburg]], [[Bürgerschaft of Bremen|Bremen]], [[Landtag of North Rhine-Westphalia|North Rhine-Westphalia]], [[Landtag of Schleswig-Holstein|Schleswig-Holstein]] and [[Landtag of Rhineland-Palatinate|Rhineland-Palatinate]]). It was also used in [[Bolivia]] in 1993, in [[Poland]] in 2001, and in the elections to the [[Palestinian Legislative Council]] in 2006. A variant of this method, the modified Sainte-Laguë method, was used to allocate the [[proportional representation]] (PR) seats in the [[Nepalese Constituent Assembly election, 2008|Constituent Assembly poll of Nepal]] in 2008. It has been proposed by the [[Green Party (Ireland)|Green Party]] in [[Ireland]] as a reform for use in [[Dáil Éireann]] elections,<ref>[http://www.greenparty.ie/news/latest_news/political_reform_vital_to_ireland_s_prosperity  Ireland's Green Party website;]</ref> and by the [[United Kingdom]] [[United Kingdom coalition government (2010–present)|Conservative-Liberal Democrat coalition government]] in 2011 as the method for calculating the distribution of seats in elections to the country's [[House of Lords|upper house]] of parliament.<ref>{{cite web |url=http://www.cabinetoffice.gov.uk/sites/default/files/resources/house-of-lords-reform-draft-bill.pdf |format=PDF |date=May 2011 |title=House of Lords Reform Draft Bill |publisher=Cabinet Office |page=16}}</ref>
 
==Description of the method==
After all the votes have been tallied, successive [[quotient]]s are calculated for each party. The formula for the quotient is<ref name="lijphart"/>
 
:: <math>quot = \frac{V}{2s+1}</math>
 
where:
 
* ''V'' is the total number of votes that party received, and
* ''s'' is the number of seats that party has been allocated so far, initially 0 for all parties.
 
Whichever party has the highest quotient gets the next seat allocated, and their quotient is recalculated given their new seat total. The process is repeated until all seats have been allocated.
 
The Sainte-Laguë method does not ensure that a party receiving more than half the votes will win at least half the seats; nor does its modified form.<ref>{{citation|contribution=Election inversions under proportional representation|url=http://userpages.umbc.edu/~nmiller/RESEARCH/NRMILLER.PCS2013.pdf|first=Nicholas R.|last=Miller|date=February 2013|title=Annual Meeting of the Public Choice Society, New Orleans, March 8-10, 2013}}.</ref> For example, with seven seats available and the votes split 53,000, 24,000 and 23,000, the allocation would be three, two and two seats respectively.

==Sainte-Laguë and Webster==
The Sainte-Laguë method is equivalent to the Webster method (named after its proponent, the U.S. senator [[Daniel Webster]]) in that they always give the same results, but the method of calculating the apportionment seems to be quite different.<ref>{{citation|title=International Encyclopedia of Political Science, Volume 1|editor1-first=Bertrand|editor1-last=Badie|editor2-first=Dirk|editor2-last=Berg-Schlosser|editor3-first=Leonardo|editor3-last=Morlino|publisher=SAGE|year=2011|isbn=9781412959636|page=754|url=http://books.google.com/books?id=t0JZp-jrotQC&pg=PA754|quotation=Mathematically, divisor methods for allocating seats to parties on the basis of party vote shares are identical to divisor methods for allocating seats to geographic units on the basis of the unit's share of the total population. ... Similarly, the Sainte-Laguë method is identical to a method devised by the American legislator Daniel Webster.}}</ref> Webster invented his method for legislative apportionment (allocating legislative seats to regions based on their share of the population) rather than elections (allocating legislative seats to parties based on their share of the votes) but this makes no difference to the calculations in the method.
 
Webster's method is defined in terms of a [[Droop quota]] as in the [[largest remainder method]]; in this method, the quota is called a "divisor". For a given value of the divisor, the population count for each region is divided by this divisor and then rounded to give the number of legislators to allocate to that region. In order to make the total number of legislators come out equal to the target number, the divisor is adjusted to make the sum of allocated seats after being rounded give the required total.
 
One way to determine the correct value of the divisor would be to start with a very large divisor, so that no seats are allocated after rounding. Then the divisor may be successively decreased until one seat, two seats, three seats and finally the total number of seats are allocated. The number of allocated seats for a given region increases from ''s'' to ''s''&nbsp;+&nbsp;1 exactly when the divisor equals the population of the region divided by ''s''&nbsp;+&nbsp;1/2, so at each step the next region to get a seat will be the one with the largest value of this quotient. That means that this successive adjustment method for implementing Webster's method allocates seats in the same order to the same regions as the Sainte-Laguë method would allocate them.
 
==Modified Sainte-Laguë method==
Some countries, e.g. [[Nepal]], [[Norway]] and [[Sweden]], change the quotient formula for parties that have not yet been allocated any seats (''s''&nbsp;=&nbsp;0) from ''V'' to ''V''/1.4. That is, the modified method changes the sequence of divisors used in this method from (1, 3, 5, 7, ...) to (1.4, 3, 5, 7, ...). This gives slightly larger preference to the larger parties over parties that would earn, with small margin, only a single seat if unmodified Sainte-Laguë's method were used. With the modified method, such small parties do not get any seat; these seats are instead given to a larger party.<ref name="lijphart"/>
 
Norway further amends this system by utilizing a two-tier proportionality. The number of members to be returned from each of Norway's 19 constituencies (counties) depends on the population and area of the county: each inhabitant counts one point, while each square kilometer counts 1.8 points. Furthermore, one seat from each constituency is allocated according to the national distribution of votes.<ref>Norway's Ministry of Local Government website; [http://www.regjeringen.no/en/dep/krd/kampanjer/the-municipal-and-county-election/the-norwegian-electoral-system.html?id=456636 Stortinget; General Elections; The main features of the Norwegian electoral system]; accessed 22 August 2009</ref>

"Why does my computer keep freezing up?" I was asked by a great deal of individuals the cause of their pc freeze problems. And I am fed up with spending much time inside answering the question time plus time again. This post is to tell we the real cause of your PC Freezes.

Install an anti-virus software. If you already have that on you computer then carry out a full system scan. If it finds any viruses found on the computer, delete those. Viruses invade the computer plus make it slower. To protect the computer from many viruses, it is actually greater to keep the anti-virus software running when we use the internet. You can furthermore fix the safety settings of the internet browser. It may block unknown and dangerous websites plus also block off any spyware or malware striving to get into your computer.

H/w connected error handling - whenever hardware causes BSOD installing newest fixes for the hardware and/ or motherboard may aid. We can also add fresh hardware that is compatible with all the system.

Always see with it which you have installed antivirus, anti-spyware and anti-adware programs and have them updated on a regular basis. This can help stop windows XP running slow.

Whenever it comes to software, this really is the vital part since it is the one running your program and also different programs required inside a functions. Always maintain the cleanliness of your program from obsolete data by getting a good tuneup utilities. Protect it from a virus online by providing a workable virus protection system. You should have a monthly clean up by running the defragmenter system. This method it will enhance the performance of your computer plus for we to avoid any mistakes. If you think something is wrong with all the computer software, plus you don't learn how to fix it then refer to a technician.

The leading reason why I couldn't make my PC run quicker was the program registry and it being fragmented. So software to defragment or clean the registry are required. Such software are called registry products. Like all additional software, there are paid ones plus free ones with their advantages plus disadvantages. To choose between your two is the user's choice.

Another problem with all the cracked version is that it takes too much time to scan the program plus while it's scanning, you cannot use the computer otherwise. Moreover, there is no technical support to these cracked versions which means in the event you get stuck somewhere, you can't ask for aid. They even do not have any customer service aid lines wherein we might call or send to resolve the issues.

Most folks make the mistake of striving to fix Windows registry by hand. I strongly suggest we don't do it. Unless you may be a computer expert, I bet we will invest hours and hours learning the registry itself, let alone fixing it. And why must you waste the valuable time in learning and fixing something we know nothing regarding? Why not allow a smart plus specialist registry cleaner do it for we? These software programs could work in a better method! Registry cleaners are very affordable as well; we pay a 1 time fee plus utilize it forever. Also, most specialist registry products are truly reliable plus simple to use. If you want more info on how to fix Windows registry, merely see my webpage by clicking the link below!
