Production is a fundamental resource for Civilization. Production represents the concept of a general pool of labor. Production is necessary for two very critical things. First, one needs to accumulate production in order to build <l:6,65>improvements<e>, units, and <l:6,64>Wonders<e>. Second, in order to build any <l:6,63>tile improvements<e> such as farms or mines, the player needs to contribute a certain percentage of production to its <l:6,61>Public Works<e>. Production is generated by assigning citizens to work certain terrain tiles. <l:6,103>Laborers<e>, <l:6,65>improvements<e>, and <l:6,64>Wonders<e> can increase Production as well.
