The sum of 41 is too small so make the modified divisor smaller. This mathematical analysis has its roots in the US Constitution specifically in 1790 when the House of Representatives attempted to apportion themselves. Find the standard divisor,. Just like Jefferson’s method we keep guessing modified divisors until the method assigns the correct number of seats. Note: Do not worry about the 0.001. The number of senators for each state is proportional to the population of the state. An apportionment method that guarantees that this will happen is said to satisfy the Quota Rule.) Note: This is not the same result as we got using Hamilton’s method in Example \(\PageIndex{4}\). Find the lower and upper quotas for each of the states in Hamiltonia. Jefferson’s Method Thomas Jefferson proposed a different method for apportionment. Quota Rule The Lower Quota is then computed as the integral (floor) part of the standard quota. Use Jefferson’s method to apportion the 25 seats in Hamiltonia from Example \(\PageIndex{2}\). Try the standard divisor as the first modified divisor. At that time the U.S. Census Bureau created a table which showed the number of seats each state would have for various possible sizes of the House of Representatives. Since 1792, five different apportionment methods have been proposed and four of these methods have been used to apportion the seats in the House of Representatives. Another, the ‘method of equal proportions’, again uses a divisor, but rounds up only if the number of seats to be allocated exceeds the geometric average of itself rounded down and itself plus 1 rounded down. Example \(\PageIndex{1}\): Jefferson’s Method. We also include a row for the geometric mean between the upper and lower quotas for each state. Ten days after the veto, Congress passed a new method of apportionment, now known as Jefferson’s Method in honor of its creator, Thomas Jefferson. This is a good way to check your arithmetic. Twenty of the 25 seats have been allocated so there are five remaining seats. There is no formula for this, just guess something. Answers are integers and/or decimals only. Watch the recordings here on Youtube! To make matters worse, the upper­quota violations tend to consistently favor the larger states. As with the other apportionment methods, the method of rounding off the quotas is what distinguishes this method from the others. That year, New York had a standard quota of 38.59 but was granted 40 seats by Jefferson’s method. Using two decimal places gives more information about which way to round correctly. It is easy to remember which way to go. The standard divisor is: \[\mathrm{SD}=\frac{\text { total population }}{\# \text { seats }} \label{sd}\]. As your first act in office, you have decided to help middle school students all over the U.S. by consolidating the states into just three, easy to remember states. 5 Distribute the surplus to the states with the largest fractional parts. Do not use a comma . Notice that the sum of the standard quotas is 25.001, the total number of seats. The terminology we use in apportionment reflects this history. Statesman and future US President Thom… If the sum is too large, make the divisor larger. Jefferson’s method divides all populations by a modified divisor and then rounds the results down to the lower quota. This is the same apportionment we got with most of the other methods. However, by the tradition established after 1842, Congress fixes the number of seats up front, with 435 seats being the norm since 1931. Apportionment can be thought of as dividing a group of people (or other resources) and assigning them to different places. The first step is to use the standard divisor as the first modified divisor. They did this for possible sizes of the House from 275 total seats to 350 total seats. Bad News­ Jefferson’s method can produce upper­quota violations! Tom is moving to a new apartment. This early tussle between Jefferson and Hamilton has a slumber of features that Try d = 11,000. Note that we must use more decimal places in this example than in the last few examples. That is due to rounding and is negligible. The standard divisor (Equation \ref{SD}) is. 4 - Is the Jefferson apportionment method susceptible... Ch. Make the standard divisor larger to get the first modified divisor. Since 23 is further from 25 than 26 is, try a divisor closer to 9480. Temporarily allocate to each state its lower quota of seats. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. If the sum is the same as the number of seats to be apportioned, you are done. If the sum is too large, pick a new modified divisor that is larger than d. If the sum is too small, pick a new modified divisor that is smaller than d. Repeat steps three through six until the correct number of seats are apportioned. Divide each state’s population by the modified divisor to get its modified quota. The methods are used to allocate seats in a On moving day, four of his friends come to help and stay until the job is done since Tom promised they will split a case of beer afterwards. Round each modified quota down to its lower quota. This veto was the first presidential veto utilized in the new U.S. government. By decreasing D by some value d, Jefferson lowers the value of the denominator of the State Quota, thus raising the quota. This time the sum is 25 so we are done. If the sum is the same as the number of seats to be apportioned, you are done. In the city of Adamstown, 42 new firefighters have just completed their training. The difference is that the cut-off for rounding is not 0.5 anymore. If the sum is the same as the number of seats to be apportioned, you are done. (Reminder: A state’s apportionment should be either its upper quota or its lower quota. Apportionment Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. The Alabama paradox was first noticed in 1881 when the seats in the U.S. House of Representatives were reapportioned after the 1880 census. Use similar calculations for the other states. 4 - Corporate Security The Huntington-Hill... Ch. Jefferson's Method causes violations. This video focuses on Jefferson's method. 4 - Campus Election Four students are running for the... Ch. Because some quotas will be rounded up and other quotas will be rounded down we do not know immediately whether the total number of seats is too big or too small. Guess #1: d = 1654. An important concept is that the number of seats a state has is proportional to the population of the state. Jefferson’s method always rounds down making the sum of the lower quotas too small. 4 - Ski Club A campus ski club is trying o decide... Ch. You have been elected president of the United States of America! The results are summarized below in Table \(\PageIndex{9}\). a method of dividing a whole into various parts. At that time, John Quincy Adams and Daniel Webster each proposed new apportionment methods but the proposals were defeated and Jefferson’s method was still used. In 1941, the number of seats in the House was fixed at 435 and an official method was chosen. Divide each state’s population by the modified divisor to get the modified quota. Starting with the state that has the largest fractional part and working toward the state with the smallest fractional part, allocate one additional seat to each state until all the seats have been allocated. The Huntington-Hill method is the method currently used to apportion the seats for the U.S. House of Representatives. You have, aptly, named these new states Stars, White Stripe, and Red Stripe (the stars and stripes, for short). All apportionment methods, but Hamilton's, violate the Quota Rule if used with the number of seats fixed. For more information contact us at info@libretexts.org or check out our status page at https://status.libretexts.org. Webster’s method rounds the usual way so we cannot tell if the sum is too large or too small right away. The total number of seats, 26, is too big so we need to try again by making the modified divisor larger. Round each modified quota up to the upper quota. For this to happen we have to adjust the standard divisor either up or down. The results are summarized below in Table \(\PageIndex{8}\). For example, Zeta’s standard quota, 4.958, has the largest fractional part, 0.958. Legal. The apportionment methods we will look at in this chapter were all created as a way to divide the seats in the U.S. House of Representatives among the states based on the size of the population for each state. Guess #1: d = 1700. Note: This is the same apportionment we found using Hamilton’s and Jefferson’s methods, but not Adam’s method. 5 Just like Jefferson’s method we keep guessing modified divisors until the method assigns the correct number of seats. Use Hamilton’s method to apportion the candy among the children. Missed the LibreFest? There is no formula for this, just guess something. 2. After Hamilton’s method was finally scrapped in 1901, Webster’s method was used in 1901, 1911, and 1931. Example \(\PageIndex{2}\): Huntington-Hill Method. Jefferson’s Method violates the Quota Rule. Have questions or comments? Both 2.48 and 2.53 would round off to 2.5. reconsidered, and after further wrangling Congress passed a new apportionment bill based on Jefferson's method, but with a common divisor of 33,000. Let’s try d = 8000. Sometimes the total number of seats allocated is too high and other times it is too low. The geometric mean \(G\) of two positive numbers \(A\) and \(B\) is, Example \(\PageIndex{1}\): Geometric Mean. 4 - Essay Contest Four finalists are competing in an... Ch. Let’s try the modified divisor, d = 10,000. All the quotas are rounded up so the standard divisor will give a sum that is too large. Video by David Lippman to accompany the open textbook Math in Society (http://www.opentextbookstore.com/mathinsociety/). The Quota Method of Apportionment, The American Mathematical Monthly, Volume 82, Number 7, August-September 1975, pages 701-730. 3 Round each one down to the lower quota Li. When we round off the standard quota for a state the result should be the whole number just below the standard quota or the whole number just above the standard quota. Try d = 9800. Jefferson’s Method of Apportionment Hamilton’s apportionment proposal was vetoed by Washington for unknown reasons. Note: The total of the lower quotas is 20 (below the number of seats to be allocated) and the total of the upper quotas is 26 (above the number of seats to be allocated). Guess #3: d = 1625. Example \(\PageIndex{4}\): Hamilton’s Method for Hamiltonia. Jefferson's Method; Province A B C D E F Total; Population : Number of seats: Standard divisor: Modified divisor: Modified Exact quota: Modified Lower quota Let’s try the modified divisor, d = 9000. The sum of 41 is too small so make the modified divisor smaller. Use Webster’s method to apportion the 25 seats in Hamiltonia from Example \(\PageIndex{2}\). Increasing the overall number of seats caused Alabama to lose a seat. The total number of seats, 23 is too small. After Washington vetoed Hamilton’s method, Jefferson’s method was adopted and used in Congress from 1791 through 1842. If the quota is more than the geometric mean between the upper and lower quotas, round the quota up to the upper quota. In the extremely rare case that the standard quota is a whole number, use the standard quota for the lower quota and the next higher integer for the upper quota. That means that d = 11,000 is much too big. \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\), 9.1: Apportionment - Jefferson’s, Adam’s, and Webster’s Methods, [ "article:topic", "showtoc:no", "authorname:inigoetal", "standard divisor", "Alabama paradox", "seats", "standard quota", "geometric mean" ], \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}} } \) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash {#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\), 9.2: Apportionment - Jefferson’s, Adams’s, and Webster’s Methods, Alpha: \[\mathrm{SQ}=\frac{\text { state population }}{\text { standard divisor }}=\frac{24,000}{9480}=2.532\], Beta:\[\mathrm{SQ}=\frac{\text { state population }}{\text { standard divisor }}=\frac{56,000}{9480}=5.907\]. Because it was important for a state to have as many representatives as possible, senators tended to pick the method that would give their state the most representatives. Later, Hamilton’s method was used off and on between 1852 and 1901. The U.S. Constitution requires that the seats for the House of Representatives be apportioned among the states every ten years based on the sizes of the populations. Congratulations! If the sum is too small, make the divisor smaller. There should be no seats left over after the number of seats are rounded off. Unlike Jefferson’s and Adam’s method, we do not know which way to adjust the modified divisor. Unfortunately for Hamilton, President Washington vetoed its selection. For more information contact us at info@libretexts.org or check out our status page at https://status.libretexts.org. Adams’s method divides all populations by a modified divisor and then rounds the results up to the upper quota. Give Alpha three seats, Beta six seats, Gamma three seats, Delta two seats, Epsilon six seats, and Zeta five seats. Example \(\PageIndex{3}\): Upper and Lower Quotas for Hamiltonia. In 1941, the House size was fixed at 435 seats and the Huntington-Hill method became the permanent method of apportionment. Hamilton’s, Adams’s, Webster’s, and Huntington-Hill’s methods all gave the same apportionment: 15 firefighters to District A, five to District B, seven to District C, six to District D, and nine to District E. Jefferson’s method gave a different apportionment: 16 firefighters to District A, five to District B, seven to District C, five to District D, and nine to District E.

The two methods do not always give the same result. Sometimes the total number of seats will be too large and other times it will be too small. The total is too large again so make the modified divisor larger. Apportionment Calculator. The standard quota for each state is usually a decimal number but in real life the number of seats allocated to each state must be a whole number. Apportionment Hamilton's Method Jefferson's Method Adams's Method Webster's Method Lowndes's Method Huntingdon-Hill's Method Dean's Method Equal Proportions Method. Using this method, District B received 70 seats, one more than its upper quota. Note: It was necessary to use more decimal places for Alpha’s quota than the other quotas in order to see which way to round off. The apportionment bill of 1832, based on Jefferson's method, gave NY 40 seats. Start by dividing each population by the standard divisor and rounding each standard quota down. This resulted in a House of 105 seatswith 19 seats for Virginia even though its quota of 105 seats was only 18.310. They always give the same results, but the methods of presenting the calculation are different. Use the standard divisor to find the standard quota for each state. District B has a standard quota of 68.969 so it should get either its lower quota, 68, or its upper quota, 69, seats. One of the most heated and contentious apportionment debates in U.S. history took place in 1832. According to Ask.com, “a paradox is a statement that apparently contradicts itself and yet might be true.” (Ask.com, 2014) Hamilton’s method and the other apportionment methods discussed in section 9.2 are all subject to at least one paradox. The upper quota is the standard quota rounded up. 4.7: Apportionment of Legislative Districts Our guess for the first modified divisor should be the standard divisor. Unfortunately for Hamilton, President Washington vetoed its selection. If the quota is less than the geometric mean between the upper and lower quotas, round the quota down to the lower quota. \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\), 9.2: Apportionment - Jefferson’s, Adams’s, and Webster’s Methods, [ "article:topic", "showtoc:no", "authorname:inigoetal" ], \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}} } \) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash {#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\), 9.1: Apportionment - Jefferson’s, Adam’s, and Webster’s Methods. This took the politics out of apportionment and made it a purely mathematical process. Missed the LibreFest? apportionment. The results are summarized below in Table \(\PageIndex{10}\). The difference between the three methods is the rule for rounding off the quotas. In this video, we learn how to use Jefferson's Method to solve apportionment problems. Apportionment methods are used to translate a set of positive natu- ral numbers into a set of smaller natural numbers while keeping the proportions between the numbers very similar. Bobby, Abby, and Charli, in that order, will get the three left over pieces this time. The sum of 24 is too small so we need to try again by making the modified divisor smaller. A mother has an incentive program to get her five children to read more. Guess #3: d = 1750. The sum of 43 is too large so make the modified divisor larger. No more memorizing 50 states and capitals. Guess #2: d = 1900. Pick a modified divisor, d, that is slightly less than the standard divisor. George Washington exercised his first veto power on a bill that introduced a new plan for dividing seats in the House of Representatives that would have increased the number of seats for northern states. A different method proposed by Thomas Jefferson was used instead for the next 50 years. Pick a modified divisor, d, that is slightly more than the standard divisor. Divide each state’s population by the modified divisor to get its modified quota. They are to be assigned to the five firehouses in town in a manner proportional to the population in each fire district. When it came to light that NY's standard quota was … Since the total of 26 seats is too big we need to make the modified divisor larger. Unlike the methods of Hamilton, Jefferson, and Webster, Lowndes’s method has never been used to apportion Congress. From Example \(\PageIndex{2}\) we know the standard divisor is 9480. None of the apportionment methods is perfect. Please NOTE: Enter only the sample sizes of the samples. The populations are listed in the following table. Legal. This is the ratio of the total population to the number of seats. The standard quota is: \[\mathrm{SQ}=\frac{\text { state population }}{\text { standard divisor }} \label{sq}\], Example \(\PageIndex{2}\): Finding the Standard Quota. Use the standard divisor as the first modified divisor. After Washington vetoed Hamilton’s method, Jefferson’s method was adopted, and used in Congress from 1791 through 1842. This time the standard divisor will be 24.19. Jefferson's method was the first apportionment method used by the US Congress starting at 1791 through 1842 when it was replaced by Webster's method. If the sum is too big, pick a new modified divisor that is larger than d. If the sum is too small, pick a new modified divisor that is smaller than d. Repeat steps two through five until the correct number of seats are apportioned. Find the standard divisor and the standard quotas for each of the states of Hamiltonia. It tells us how many people are represented by each seat. Use the Huntington-Hill method to apportion the 25 seats in Hamiltonia from Example \(\PageIndex{2}\). Webster’s method divides all populations by a modified divisor and then rounds the results up or down following the usual rounding rules. Example \(\PageIndex{2}\): Adams’s Method. Here's Balinski & Young's 1974 apportionment method which is both house-monotone and obeys quota: Let P k denote the population, and S k the number of seats assigned so far, to state k. We initially assign all states 0 seats: S k =0. Rounding off the standard quota by the usual method of rounding does not always work. The next step is to find the standard quota for each state. Round each modified quota to the nearest integer using conventional rounding rules. Note that the geometric mean between A and B must be a number between A and B. In this example the geometric mean of 5.477 is between 5 and 6. The number of seats in the House has also changed many times. This veto was the first presidential veto utilized in the new U.S. government. Try again making the modified divisor larger. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. From Example \(\PageIndex{2}\) we know the standard divisor is 9480 and the sum of the lower quotas is 20. These values are called the lower and upper quotas, respectively. Guess #1: d = 1654. Alpha gets two senators, Beta gets six senators, Gamma gets three senators, Delta gets two senators, Epsilon gets seven senators, and Zeta gets five senators. Look at District D. It was really close to being rounded up rather than rounded down so we do not need to change the modified divisor by very much. The LibreTexts libraries are Powered by MindTouch® and are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. We know the divisor must be between 8000 and 9000 so let’s try 8500. Apportion the new firefighters to the fire houses using Hamilton’s, Jefferson’s, Adams’s, Webster’s, and Huntington-Hill’s methods. The Jefferson Method avoids the problem of an apportionment resulting in a surplus or a deficit of House seats by using a divisor that will result in the correct number of seats being apportioned. Guess #4: d = 1775. Notice that adding another piece of candy (a seat) caused Dave to lose a piece while Abby and Charli gain a piece. Jefferson’s method was under-representing New England states, where Webster was from. This is the exact number of seats that should be allocated to each state if decimal values were possible. The Huntington-Hill method starts out similarly to Webster’s method since some quotas are rounded up and some quotas are rounded down. In Adams’s method the standard divisor will always give us a sum that is too big so we begin by making the standard divisor larger. Barry Cipra, E Pluribus Confusion, American Scientist, Volume 98, Number 4, July-August 2010, pages 276-279. In mathematics and political science, the quota rule describes a desired property of a proportional apportionment or election method. The lower quota is the standard quota rounded down. But we did see some drawbacks of this method, in particular the “Alabama Paradox” as presented in class when assigning teachers to each math course. Thomas Jefferson, who lived before any of these paradoxes, proposed a different method for apportionment. The sum is 42 so we are done. Jefferson’s, Adams’s, and Webster’s methods are all based on the idea of finding a divisor that will apportion all the seats under the appropriate rounding rule. They will go to Ed, Bobby, and Dave, in that order, since they have the largest fractional parts of their quotas. Now the total is too small so make the modified divisor smaller. Guess #2: d = 1600. Watch the recordings here on Youtube! It sounds like a fairly simple job to split the case of beer between the five friends until Tom realizes that 24 is not evenly divisible by five. In Jefferson’s method the standard divisor will always give us a sum that is too small so we begin by making the standard divisor smaller. The minutes are listed below in Table \(\PageIndex{6}\). Use Adams’s method to apportion the 25 seats in Hamiltonia from Example \(\PageIndex{2}\). Huntington-Hill’s method rounds off according to the geometric mean. Jefferson's method was used with such a fixed ratio. Example \(\PageIndex{3}\): Comparison of all Apportionment Methods. Pick a modified divisor, d, that is slightly less than the standard divisor. Jefferson’s method was the first method used to apportion the seats in the U.S. House of Representatives in 1792. The total number of seats, 26, is too big so we need to try again by making the modified divisor larger. The question is how to divide the four remaining beers among the five friends assuming they only get whole beers. Hamiltonia, a small country consisting of six states is governed by a senate with 25 members. Webster’s method was later chosen to be used in 1842 but Adams’s method was never used. This is an example of the Alabama paradox. The total number of seats is smaller like we hoped but 22 is way too small. Guess #1: d = 1600. As we will see in the next section, each of the methods has at least one weakness. In Example \(\PageIndex{2}\) the total number of seats allocated would be 26 if we used the usual rounding rule. Use Hamilton’s method to finish the allocation of seats in Hamiltonia. Guess #2: d = 1550. Adams’s method always rounds up making the sum of the upper quotas too large. An example is the ‘Adams method’ of apportionment, which is similar to the Webster and Jefferson methods, except that the number of seats is rounded up. The sum is 42 so we are done. This table showed a strange occurrence as the size of the House of Representatives increased from 299 to 300. However, in some situations, the results depend on the method used. This means that each seat in the senate corresponds to a population of 9480 people. All the quotas are rounded down so using the standard divisor will give a sum that is too small. He could start by giving each of them (including himself) four beers. Our guess for the first modified divisor should be a number smaller than the standard divisor. If the sum is too big, pick a new modified divisor that is larger than d. If the sum is too small, pick a new modified divisor that is smaller than d. Repeat steps two through five until the correct number of seats are apportioned.
