A small country consists of ve states, whose populations are A : 810, 000 B : 473, 000 C : 292, 000 D : 594, 000 E : 211, 000 If the legislature has 119 seats, apportion the seats using (a) Hamilton's Method (b) Jeerson's Method (c) Webster's Method (d) Huntington-Hill Method (e) Lowndes' metho
A. Hamilton Method :
Total Seats | 119 | |||
Divisor | 20000 | |||
States | Population | Quota | Initial | Final |
A | 810000 | 40.50 | 40 | 40 |
B | 473000 | 23.65 | 23 | 24 |
C | 292000 | 14.60 | 14 | 15 |
D | 594000 | 29.70 | 29 | 30 |
E | 211000 | 10.55 | 10 | 10 |
Total | 2380000 | 119 | 116 | 119 |
The Divisor is obtained by dividing the total of population by total no of seats, which is 2380000/119.
The Quota is obtained by dividing the population with the divisor. The numbers highlighted in green are added 1 seats in the final quota , which takes the final total to 119.
B. Jefferson's Method :
Total Seats | 119 | |||
Standard Divisor | 20000 | |||
Modified Divisor | 19700 | |||
States | Population | Quota | Initial | Final |
A | 810000 | 41.12 | 41 | 41 |
B | 473000 | 24.01 | 24 | 24 |
C | 292000 | 14.82 | 14 | 14 |
D | 594000 | 30.15 | 30 | 30 |
E | 211000 | 10.71 | 10 | 10 |
Total | 2380000 | 120.81 | 119 | 119 |
The Quota is obtained by dividing the population with the standard divisor. The sum total was 116. Now , the divisor is reduced until the number of seats , that are apportioned total to 119. Thus , we get the modified divisor as 19700.
C.Webster's Method :
In this case,
Total Seats | 119 | |||
Standard Divisor | 20000 | |||
Modified Divisor | 20100 | |||
States | Population | Quota | Initial | Final |
A | 810000 | 40.30 | 40 | 40 |
B | 473000 | 23.53 | 24 | 24 |
C | 292000 | 14.53 | 15 | 15 |
D | 594000 | 29.55 | 30 | 30 |
E | 211000 | 10.50 | 10 | 10 |
Total | 2380000 | 118.41 | 119 | 119 |
When we divided the Population by standard divisor, we got the quota, when we rounded it off, we got the sum as 121. Now , we increased the divisor to 20100. Now ,when we round off the allocated quotas, we get the total as 119.
D. Huntington-Hill Method :
Total Seats | 119 | ||||
Standard Divisor | 20000 | ||||
Modified Divisor | 20100 | ||||
States | Population | Quota | Lower Quota | Geometric Mean | Final |
A | 810000 | 40.299 | 40 | 40.49691346 | 40 |
B | 473000 | 23.532 | 23 | 23.49468025 | 24 |
C | 292000 | 14.527 | 14 | 14.49137675 | 15 |
D | 594000 | 29.552 | 29 | 29.49576241 | 30 |
E | 211000 | 10.498 | 10 | 10.48808848 | 10 |
Total | 2380000 | 118.41 | 116 | 118.4668213 | 119 |
Geometric Mean is obtained by the formula , where n is the lower quota.
The highest of the geometric mean and the quota is considered and they are rounded off to get the final. The sum of final is calculated. If it is more than the total seats, then the modified divisor is used and the process is repeated until we get the sum of final apportion as total seats. In this case, the final allocations are shown in the table.
