How have technological advances in transportation made migration easier, from the Age of Exploration to modern times?

Answer:

During the Age of Exploration, improved sailing ships could travel farther across oceans and carry more people and supplies, making long-distance migration possible. Later, steamships and railroads made journeys faster, more reliable, and less costly. In modern times, cars, highways, and airplanes have made it easier to travel quickly between regions and countries, so people can migrate farther and with fewer travel barriers.
