Age Structure

The median age in Pima County was 32.8 in 1990 (slightly below the national average), 35.7 in 2000 and was estimated as 36.7 in 2007. The slow rise of the median age is due to the aging of the Baby Boomers, not to any massive influx of seniors. Much of metropolitan Tucson's growth over the next 20 years will be driven by working age people moving here for employment opportunities.
