The International Organisation for Migration (IOM) has said 73 per cent of Rohingyas are now living in new spontaneous settlements.
IOM's newly-released Needs and Population Monitoring (NPM) Round 7 assessed 1,635 locations hosting Rohingya refugees in collective sites and host communities in Bangladesh.
The organisation also said on Sunday that some 13 per cent Rohingyas are now living in makeshift settlements.
"9 per cent in host community locations and 5 per cent in the formal refugee camps," IOM said.
Compared to the previous round, there has been a reduction in the proportion of Rohingyas in host community locations and an increased proportion residing in collective sites.
On Christmas day it will be four months since the start of the influx of Rohingyas into Bangladesh.
Latest figures show 655,000 people have arrived in that period, bringing the estimated total number of Rohingyas in Cox's Bazaar to 867,500.
As winter takes hold, IOM and its partners said they are scaling up their distribution of shelter and non-food items in response to the colder weather.
In the past fortnight, distributions have included over 88,500 blankets and emergency shelter materials, including bamboo bundles for over 1,500 families.
According to UNB, IOM has distributed 124,000 tarpaulins, benefitting some 563,000 new arrivals. Some 32,000 people have also received other non-food relief items.
IOM said they are also supporting the Rohingyas and the affected local population with water, hygiene and sanitation.
