The number of happy/content/unhappy people is a calculated number depending upon your difficulty level and adjusted by factors such as luxuries connected, happiness buildings/wonders and commerce redirected to luxuries.
So at level 1 where 25% of people are unhappy.....does this mean that 25% of your total population goes from content to unhappy, or from happy to unhappy? And is it irrespective of any other happiness influences? For example, you have a size 11 city with 6 happy, 2 content and 3 unhappy citizens (after the effect of some happiness buildings, luxuries, etc). Once you get to level 1, does this mean that your unhappy citizens increases by 25% x 11 = 2.75, rounded down to 2?.....meaning your 2 content citizens now become unhappy? Any change to the 6 happy citizens?
Think of unhappiness and happiness as points: unhappiness points (up) and happiness points (hp). Each city has several causes that modifies those two numbers, and the final up and hp numbers after all modifications are displayed as happy or unhappy people.
First, all up are counted. It starts with one up for each citizen above the number born happy (9 in your size 11 city if playing on regent. Assume that you have improvements/wonders that make totally 6 unhappy->content and 6 luxuries. The improvements will reduce the up from 9 to 3. The luxuries will then increase th hp from zero to 6, for a total of 6 hp and 3 up, giving 6 happy, 3 unhappy and the rest (2) content.
Now, if the 25% WW kicks in, there will be 4 more up (25% of 11), thus your total up before content/happiness modification becomes 13 (more than your number of citizens). If you only had one temple in the city, all citizens would still be unhappy, since the temple would reduce the up from 13 to 12, still more than the number of citizens.
But with 6 unhappy-content improvements you'll get the up reduced from 13 to 7. The first 4 luxuries will increase the hp from zero to 4, leaving 4 hp and 7 up.
Now the number of hp + up is equal to the number of citizens, and therefore the next luxury point cannot just increase hp by one, but will instead be treated as a content->happiness point which reduces the up by one (to 6), and the last luxury point can then increase the hp by one (to 5).
The city will therefore end up with 5 happy and 6 unhappy people, giving unrest in your city.
A simpler way of calculating the additonal WW effect is to start with your 6 happy, 2 content and 3 unhappy, and then for each of the 4 new up, make one content unhappy - if there are no content, make one happy content.
