This is the last step I'll be doing. There are also some additional steps for aiding/GB boosts, quest looping, and factoring in the coins from adding the population, but I'm going to finish with this one because the numbers for the other three steps can change drastically and some parts of two of those steps will not be applicable to others.

First part of the population space is finding the building we're taking population from. I'm going to use a Condominium, but this will likely change if the 1-day houses for the TE is improved enough. A Condominium's population/space is (2800/5x4)=140 population/space. Before we forget, I'm also going to add an additional 1 happiness/space to that system since the Condominium uses roads

(though that will barely make a difference

) Now factoring in that space, we have (250/140=) an extra 1.786 spaces for population.

We are not done yet though. Now we need to factor in the happiness needed to keep the population delighted (we're still using 200 happiness/space). Since we've used 250 population, we need (1.4*250=) 350 additional happiness. Now we subtract 1.786 happiness from it because remember the Condominium system gives 1 happiness/space, and dividing your final answer by 200 gives us an additional 1.741 spaces.

Using the same calculation steps (or multiplying by a factor of 550/250 (populations for both buildings)), the PSC takes an additional 3.929 for just the population and additional 3.830 spaces for happiness to keep the population delighted.
