* Sahuarita was incorporated in 1994. Sahuarita 1990 population was estimated from census tracts approximate to the incorporation limits of the town. The 1990 unincorporated Pima County population includes the population of Sahuarita because Sahuarita was not incorporated in 1990. As a result, the sum of the population for unincorporated Pima County and all jurisdictions (including the Sahuarita estimate) is 1,629 greater than the total Pima County population.


From 1990 to 2000, Marana experienced the highest growth rate of any AZ city or town (519%)
From 1990 to 2000, Oro Valley had the second highest growth rate in the state (345%)
Pima County growth rate since 1980 = 59%
