The California Teachers Study is made up of female teachers and administrators who were all active members of the California State Teachers' Retirement System (CalSTRS) in 1995. Today, some of our participants are still employed as California teachers while others have moved on to other professions or are retired.
Participants live throughout California and represent various socioeconomic backgrounds.
At study enrollment, CTS participants:
ranged in age from 22 to 104 with a median age of 53
were less likely to have biological children compared with other women in California at the time
were more likely to have had their first child at a later age on average than other women in California at the time
represented various racial and ethnic groups: 87% were white, 2.7% were African American, 4% were Hispanic, 3.4% were Asian/Pacific Islander, 1.0% were Native American, and 2.1% identified as other, mixed, or did not specify their race/ethnicity.
