To Calculate Ratio Share
Divide the town population by the total population – this assigns each town their share of the floterial plus their dedicated seats – divide by total seats and convert to percentage
3,286 ÷ 27,640 = .1188 = 11.9%
To Calculate Deviation
Ratio Share + Other Seats in Town = Adjusted Number of Seats
1 + .119 = 1.119
Town Population ÷ Adjusted Seats = Component Population
3286 ÷ 1.119 = 2936.55
(Component Population – Ideal Population) ÷ Ideal Population =
2936.55 – 2773 = 163.55 ÷ 2773 = .0589 = 5.89%
