How can I Analyse the Evolution of Student Flows over time for Specific Destinations using the Silhouette/ Benchmark Reports?

This article explains how to analyse changes in international student flows over time for specific destination countries (or regions) using the Silhouette and Benchmark reports in the Global Students Flow dataset.

Overview

There are two ways to analyze the evolution of student flows over time for specific destinations through two Global Student Flow dataset reports:

  • Silhouette report: high-level visual of where students come from or go to; good for exploring composition and trends for a single destination or source.

  • Benchmark report: side-by-side time-series comparison across multiple destinations or peer groups; includes a zoom feature for detailed time-range focus.


Using the Silhouette Report

  1. Open the Global Students Flow dataset.

  2. Select “Silhouette” from the Reports menu.

3. Set Source / Destination filters:

  • Use the top filter bar to choose the Destination you want to analyze

  • Optionally set the Source filter to restrict origins (e.g., a region or specific country).

4. Choose the time period:

  • Use the Time Period control to pick the start and end year (or available granularity).

  • The Silhouette will update to show evolution across the selected period.

5. Interpret the visualization:

  • Hover over segments or map markers to see numeric flow values and year breakdowns.

  • Use the legend to toggle categories on/off for clarity


Using the Benchmark Report (compare destinations over time)

  1. Open the Global Students Flow dataset and select “Benchmark.”

2. Select Destination(s):

  • In the top filter bar, choose the primary Destination you want to analyse.

  • Add additional Destinations or peer countries to compare (use the “Add comparison” or + control).

3. Set Source filter (optional):

  • If you want flows from a specific origin (e.g., a country or region), set the Source filter to focus the comparison.

4. Choose the time period:

  • Use the Time Period selector to pick years. Benchmark will plot each destination’s time series across that range.


Using the Zoom Feature:

  • Clicked Zoom button to inspect finer trend details and compare short-term changes.

Practical Tips

  • Start with Silhouette to identify a destination’s major source countries, then move to Benchmark to compare time trends with peers.

  • If the chart appears empty for a selected period, reduce filters (broadening Source or Destination) or expand the Time Period range.

  • Use the legend to simplify charts if many destinations are plotted.
