Crossing
Lines

Four people face four different landscapes of movement. Distance matters—but law, money, danger, credentials, borders, and human networks decide what distance means.

Enter the journey.

This lab asks not merely how far people move, but who can move, along which path, under what legal category, at what cost, and with what choices left.

The geographic question

Why can one person cross an ocean in a day while another waits years to cross a border visible from home? A mile is a unit of distance. It is not a unit of possibility.

A model, not legal advice

The travelers are teaching composites. Scores are qualitative indices, not forecasts. Real cases depend on changing laws, individual circumstances, and decisions made by governments and agencies.

01

Meet four travelers

Choose a person. Notice that each journey begins with a different legal category, resource bundle, and geography. “Migrant” describes movement; it does not describe one kind of person.

World map of the four migration journeys Four selectable routes connect Darfur with eastern Chad, Guatemala with the United States, coastal Bangladesh with Dhaka, and Seoul with Toronto. Locations are positioned by latitude and longitude.

Geographic guide: coastlines use Natural Earth data and locations are plotted from latitude and longitude. Route lines show the journeys at world scale, not exact travel itineraries.

02

Navigate one journey

At each gate, choose among options that real migrants may confront. There is rarely a perfect answer. The model records tradeoffs in money, safety, legal security, family connection, and time.

03

Distance is only one kind of friction

Compare each traveler’s straight-line journey with the effective friction surrounding it. The bars are explanatory teaching indices, not measured probabilities.

04

Change the rules around the traveler

You have three policy points. Select interventions and watch their effects differ across all four journeys. A policy that helps one traveler may barely touch the obstacle facing another.

Select a policy to see who benefits most—and who remains constrained.
05

Build a geographic explanation

Select three pieces of evidence. The lab will assemble them into an argument you can evaluate. Choose evidence that explains a mechanism, not merely a sad or hopeful outcome.

Your explanation

Choose three evidence cards to construct an argument.
