 The population of the municipality has stagnated, and even declined, slowly but steadily, since the early 1990s.The increase in population brought with it an increase in the size of what is now called Greater Guadalajara, rather than an increase in the population density of the city.Migrants coming into Guadalajara from the 1940s to the 1980s were mostly from rural areas and lived in the city center until they had enough money to buy property.
