SUICIDE RATE
Mae La, a sprawling expanse of thatched bamboo huts ringed with barbed wire and set among hills, was established in 1984.
It is considered better off than the other camps - all called "temporary shelters" - as it has electricity and mobile and internet services, as well as schools until grade 12.
There are also shops, clinics, community centres, playgrounds and places of worship.
In Mae La's Zone C, there is a bustling market of shops selling household articles, food and snacks; there are also tailors and hair salons. Motorbikes, which refugees are not officially allowed to own, are parked everywhere.
But the makeshift homes are crowded together next to open drains. Depression is common, as are alcohol- and substance-abuse.
The suicide rate in Mae La is three times the global average, according to a 2017 report by the International Organization for Migration.
Since Myanmar transitioned to a civilian government, the Thai authorities have said they want to close all the camps.
Developments in Myanmar offer "real opportunities for safe and dignified voluntary return," a UNHCR spokeswoman said.
If some individuals were unable to return, then UNHCR and the Thai authorities would handle them on a case-by-case basis, she said.
But campaigners say conditions are not yet conducive.
"If the camps are closed now, it would leave refugees vulnerable to traffickers and other dangers," said Kyaw Win, director of the Burma Human Rights Network.
"Instead, Thai authorities should open up employment opportunities for them to settle in Thailand and contribute to the country's economy," he said.
That is what Pa Pa Win wants for her family.
"We would like our children to finish their education, be able to leave this camp, get a job, live like others do," she said.
"But we do not know what our future is."
