hree educational establishments may be built in your cities: schools, academies, and libraries.

In order to evolve, even fairly basic houses need the services of a nearby educational establishment. The more evolved the house becomes, the greater its need for access to more education; very advanced housing requires access to all three educational buildings. For more on house evolution, see Page 41.

Besides giving individual houses access to education buildings, the city has a more general duty to educate young people. The total number of people of school age (up to 13 years' old) and academy age (14 to 21 years' old) in your population determines your overall demand for schools and academies. For fast-growing, newer cities, the number of educational establishments needed to allow housing to evolve is probably more than enough to educate all the children. Once the city grows substantially, though, your city probably has many more youths to educate than are served by the schools and academies you built just to provide access for housing. You might need to build additional educational establishments.

The overall supply of education in your city affects your Culture rating. Classroom size is the key to raising the education component of your Culture rating: smaller classrooms (as calculated from the number of school- or academy-aged children and the number of working schools or academies in your city) yield a much higher Culture rating. Failure to educate all the people of relevant age hurts your city's Culture rating. One school can educate 50 pupils, while one academy can educate 100.

Adults want access to libraries throughout their lives; one library can serve 800 people.
