|Denmark ranked first on the list of countries whose citizens readily engage in black market labour, according to business daily Erhvervsbladet.
New figures from the Rockwool Foundation Research Unit indicated that 20 percent of all Danes - more than one in every five - work at some time or another for unregistered cash. This was considerably more than the number of black market workers in Sweden, Norway, Germany or Britain, whose figures ranged from eight to 17 percent.
"These numbers document Denmark's leading position in black labour, calculated according to the percentage of the population. In Germany, people work longer on the black market, so the extent of the problem is roughly the same, if not greater," said Rockwool Foundation spokesperson S�ren Pedersen.
