The number of refugees, asylum-seekers and internally displaced persons in the world by the end of 2016 totaled a record high of 65.6 million people.
Last year, much of the news coverage focused on refugee resettlement to developed countries, including efforts by some states to restrict access and even erect border barriers.
The report tracked three types of movement: refugees, internal displacement and asylum-seekers.
Uganda received the largest number of new refugees in 2016 in the world, said new figures released by the UN Refugee Agency (UNHCR) on Monday.
While people continued to flee in record numbers, the report found that past year around one half million refugees returned home and about 6.5 million internally displaced people went back to their places of origin although "many did so in less than ideal circumstances and facing uncertain prospects".
"By any measure this is an unacceptable number", U.N. High Commissioner for Refugees Filippo Grandi said in a statement.
While 10.3 million people fled previous year, almost 7.2 million refugees and internally displaced people returned home or started new lives under long-term resettlement programmes in Western countries.
The conflict in Syria, now in its seventh year, was the world's biggest producer of refugees (5.5 million).
About 40,000 South Sudanese refugees have entered Uganda every month over the past year, 86 per cent of them women and children, said the World Refugee Council, a new organization run by Canada's Centre of International Governance Innovation.
Conflicts in Syria and South Sudan have dramatically driven up numbers.
The global community should do more to help South Sudan, U.N. High Commissioner for Refugees Filippo Grandi, said after visiting a camp for the displaced.
"The historic high displacement figures must foster more dedicated work for political solutions, increase funding to meet humanitarian needs, and bring a larger willingness among all countries to take their share of the responsibility".
Thirty-seven countries have taken in refugees, and most refugees (84 percent) were in developing nations, because they tend to be closest to areas of conflict.
Turkey was also the world's fourth-largest recipient of individual asylum claims in 2016, according to the UNHCR. Significant numbers of refugees in Uganda also came from the Democratic Republic of the Congo (205,400), Burundi (41,000), Somalia (30,700), and Rwanda (15,200).

Musa Ecweru, minister for refugees, told Anadolu Agency: "We want the global community to lift the pressure and fix the damage the refugees are putting on the limited resources in the communities that host them".
"I think this year the budget will be fundamentally stable". The 39-year-old mother of eight said she was chased by men with guns when she went out to collect firewood. "It is not just in respect to refugee aid, but it is in general regarding foreign aid".
