Mathematics of Computing Your City's Indices

The Mathematics of Computing Your City's Indices (Updated 5/22/2019)Here is a comprehensive guide to the mathematics behind the indices used in Metropolis.

ACCOMMODATION INDEX (AI)

Formula: AI = (Total AI Points) / (Population)

City Effects:

- AI between 0.000 and 0.999: Increases Welfare Costs of your city by between 10 and 80% (I do not know the
exact cutoff values yet.)
- AI between 1.000 and 1.100: No effect.
- AI between 1.100 and 1.199: Increases population gained in Daily Census by 1%.
- AI between 1.200 and 1.299: Increases population gained in Daily Census by 2%.
- AI between 1.300 and 1.399: Increases population gained in Daily Census by 3%.
- AI between 1.400 and 1.499: Increases population gained in Daily Census by 4%.
- AI between 1.500 and 1.599: Increases population gained in Daily Census by 5%.
- AI between 1.600 and 1.699: Increases population gained in Daily Census by 6%.
- AI between 1.700 and 1.799: Increases population gained in Daily Census by 7%.
- AI between 1.800 and 1.899: Increases population gained in Daily Census by 8%.
- AI between 1.900 and 1.999: Increases population gained in Daily Census by 9%.
- AI at or above 2.000: Increases population gained in Daily Census by 10%.

HEALTH INDEX (HI)

Formula: HI = (Total HI Points) / (Population - 1200)

the result by 10.)

normal population growth rate.

by double the normal population growth rate.

- HI between 0.500 and 0.899: Increases welfare costs by 20% and decreases city population during Daily Census

by the normal population growth rate.

- HI between 0.900 and 0.999: No effect to welfare costs and no effect to city population during Daily Census.

- HI between 1.000 and 1.099: Decreases welfare costs by 10% and increases city population during Daily Census

by the normal population growth rate.

- HI between 1.100 and 1.499: Decreases welfare costs by 20% and increases city population during Daily Census

by double the normal population growth rate.

- HI at or above 1.500: Decreases welfare costs by 30% and increases city population during Daily Census by triple

the normal population growth rate.
