The Jefferson and the D'Hondt methods are equivalent. They always give the same results, but the methods of presenting the calculation are different.
 
The method was first described in 1792 by Statesman and future US President [[Thomas Jefferson]], in a letter to [[George Washington]] regarding the apportionment of seats in the [[United States House of Representatives]] pursuant to the [[1790 United States Censuscensus|First United States Census]]:<ref name=":0" />
 
{{blockquote|For representatives there can be no such common ratio, or divisor which ... will divide them exactly without a remainder or fraction. I answer then ... that representatives [must be divided] as nearly as the nearest ratio will admit; and the fractions must be neglected.}}

In the [[Netherlands]], a party must win enough votes for one strictly proportional full seat (note that this is not necessary in plain D'Hondt), which with 150 seats in the lower chamber gives an effective threshold of 0.67%. In [[Estonia]], candidates receiving the simple quota in their electoral districts are considered elected, but in the second (district level) and third round of counting (nationwide, modified D'Hondt method) mandates are awarded only to candidate lists receiving more than the threshold of 5% of the votes nationally. The vote threshold simplifies the process of seat allocation and discourages fringe parties (those that are likely to gain very few votes) from competing in the elections. Obviously, the higher the vote threshold, the fewer the parties that will be represented in parliament.<ref>{{Cite web|url=http://faculty.georgetown.edu/kingch/Electoral_Systems.htm|title=Electoral Systems|first=Charles|last=King|website=Prof. King’s Teaching and Learning Resources|access-date=2018-05-05}}</ref>
 
The method can cause a ''natural threshold''.<ref>{{Cite report |author=Venice Commission |date=2008 |title=Comparative report on thresholds and other features of electoral systems which bar parties from access to parliament |url=http://www.venice.coe.int/webforms/documents/default.aspx?pdffile=CDL-AD(2008)037-e |publisher=Council of Europe |access-date=February 14, 2016 }}</ref><ref>{{cite book |last1=Gallagher |first1=Michael |last2=Mitchell |first2=Paul |date=2005 |title=The Politics of Electoral Systems |chapter-url=http://www.blogary.ro/wp-content/uploads/2011/10/The_Politics_of_Electoral_Systems.pdf |archive-url=https://web.archive.org/web/20151010090047/http://www.blogary.ro/wp-content/uploads/2011/10/The_Politics_of_Electoral_Systems.pdf |archive-date=2015-10-10 |publisher=[[Oxford University Press]] |chapter=Appendix C: Effective threshold and effective magnitude |isbn=9780199257560}}</ref> It depends on the number of seats that are allocated with the D'Hondt method. In [[Elections_in_FinlandElections in Finland#Parliamentary_electionsParliamentary elections|Finland's parliamentary elections]], there is no official threshold, but the effective threshold is gaining one seat. The country is divided into districts with different numbers of representatives, so there is a natural threshold, different in each district. The largest district, [[Uusimaa]] with 33 representatives, has a natural threshold of 3%, while the smallest district, [[South Savo]] with 6 representatives, has a natural threshold of 14%.<ref>Oikeusministeriö. [http://www.om.fi/uploads/p0yt86h0difo.pdf Suhteellisuuden parantaminen eduskuntavaaleissa.]</ref> This favors large parties in the small districts.
In [[Croatia]], the official threshold is 5% for parties and coalitions. However, since the country is divided into 10 voting districts with 14 elected representatives each, sometimes the threshold can be higher, depending on the number of votes of "fallen lists" (lists that do not receive at least 5%). If many votes are lost in this manner, a list that gets 5% will still get a seat, whereas if there is a small number votes for parties that do not pass the threshold, the actual ("natural") threshold is close to 7.15%.
Some systems allow parties to associate their lists together into a single "cartel" in order to overcome the threshold, while some systems set a separate threshold for such cartels. Smaller parties often form pre-election coalitions to make sure they get past the election threshold creating a [[coalition government]]. In the Netherlands, cartels (''lijstverbindingen'') (until 2017, when they were abolished) could not be used to overcome the threshold, but they do influence the distribution of remainder seats; thus, smaller parties can use them to get a chance which is more like that of the big parties.
