The vertical axis ranges from 0 to 1 in increments of 0.1 units. The horizontal axis contains two labeled categories. From left to right, the labels are “P h.D. in 2004” and “Ph.D. in 2006”. Each category has one stacked bar divided into three color-coded segments representing academic positions: “Non-tenured” in dark red at the bottom, “Tenured assistant professors” in dark blue in the middle, and “Associate and full professors” in light blue at the top. The data for the bars on the graph are as follows: P h.D. in 2004: Non-tenured: 0.51. Tenured assistant professors: 0.46. Associate and full professors: 0.03. P h.D. in 2006: Non-tenured: 0.75 Tenured assistant professors: 0.24 Associate and full professors: 0.01 Note: All numerical data values are approximated.Tenured and non-tenured PhD holders by cohort
