This chart compares changes in doctorates received by field of study for males and females and for U.S. citizens (including permanent visa holders) and foreign students (temporary visa holders).
The bubbles represent fields of study. Hover the mouse over one to see the name, or click on it to add a label. Click the play button in the lower left to begin an animation of change over time. You can also click and hold on the slider to progress through time manually. If you select a field of study and the "Trails" box at bottom right is checked, the animation will leave a year-by-year record.
For the purpose of this demonstration, data points are interpolated between 5 year estimates. Figures in this demonstration have not yet been formatted to NCSES publication guidelines.
You can also view the data on an animated bar chart or a line graph by selecting a tab at top right above the chart.
The tool being used is a Google motion chart gadget, which was originally developed by Hans Rosling and gapminder.org
