Migrants at the southern border used to be mostly single men from Mexico. Twenty years later, the makeup of that population has changed dramatically.
The biggest difference now is that a majority of the population includes migrant families from Central America and children traveling alone or without a parent.
Better job opportunities aren’t necessarily the main reason that migrants are heading north. Many now say they’re fleeing criminal gangs and dire poverty.
Dallas-based photographer Dylan Hollingsworth visited Tijuana, Mexico, in January and photographed migrants who had traveled in caravans from Central America. None had tried to cross the U.S. border to seek asylum, but some had gotten a number and are waiting in line for an interview, to get the process started.
