* Prior to 1989, the Colorado Health Department capped their records of educational attainment at 17 years. (representing less than 5% of the records). During these years, parents with more than 17 years of education were recorded as 17. Beginning in 1989 this cap was removed, slightly skewing mean education towards a lower value prior to 1989. Education numbers are rounded to the nearest decimal point.
