Mostly by car or bus. The cities that have it, such as Mexico City, Guadalajara or Monterrey, have an underground metro system. For inter-city transport, light rail can be used. For inter-state transport, car or bus is most usually used as Mexico has an interstate highway system much like the US'. However "cheap airlines" and some railroad can be used. Whenever available, ferries can be found.
Most people walk through or use buses in the streets of mexico while other use cars, trucks and motorcycles to get through roads and highways.

By moving from place to place
Yes but they need to get visa
People would often travel to Mexico in caravans. Caravans are groups of people going to a place in a group. They did this so that bandits or robbers would most likely notice the large group and not bother them.
I do not know except is it cheap. But you can go farther south in central America and in the caribbean just as cheap. Mexico is filthy and unsafe. Travel elsewhere!
Yes, of course. Mexico is a popular tourist destination; the second largest in the Americas (after the United States).
It was easier for people to travel and trade on, from Missouri to New Mexico.
If you mean NEW Mexico, no; it would be a domestic travel. If you mean Mexico the country, yes, it would be international travel.
Travel was not restricted into Mexico, so many people continued to travel in and out of the country. Many international airports were screening people for symptoms as they entered the countries from Mexico and the US and, in some cases, they were retained without entry until medically examined to determine if ill with flu-like illness, but that was only done in some countries. At one point early in the epidemic in North America the US State Dept. recommended to US citizens that travel to Mexico be restricted to "essential only." At that time most people reduced travel into Mexico but "essential" travel was still happening. Many vacationers did reschedule their trips into Mexico, but some continued to go to locations outside the larger cities (and especially avoided areas near Mexico City where the epidemic was rapidly spreading and where the new virus was first discovered.)
Buses, subways, trams, taxis (cabs) qualify as such.
