BERLIN -- Germany's Federal Office for Statistics says some 42,300 unaccompanied minors entered the country from abroad last year.
The office said in a statement Tuesday that this was an increase of 30,700, or 263 percent, compared with the previous year.
About 91 percent, or some 38,700, of these children and teenagers were male, while only about 3,600 girls entered Germany without their parents.
Germany saw an unprecedented influx of migrants in 2015. More than 1 million people registered for asylum, the majority of them from Syria, Afghanistan and Iraq.
Unaccompanied refugee children are normally taken into care by the country's youth welfare offices.
Meanwhile on Tuesday, the International Organization for Migration (IOM) announced that the bodies of 120 migrants have washed up on Libyan beaches over the past 10 days, the Reuters news agency reported.
In total, 4027 refugees or migrants have died so far in 2016, with three-quarters of that number made up of people travelling across the Mediterranean while trying to reach Europe, IOM spokesman Joel Millman told a briefing.
