An average of 3.74 million people were out of work in April and May, and 1.9 million of them had no source of income, according to a government report released Tuesday.

The Public Management, Home Affairs, Posts and Telecommunications Ministry said that of those who did have income, 770,000 were claiming unemployment benefits and 330,000 were drawing on public pensions.

The ministry carried out in April and May a special survey on jobless people in addition to its monthly employment survey. The special survey covered about 20,000 households.

The first of its kind, the survey looked into the type of income received by households whose main breadwinners were out of work.

It found that 23.9 percent of such households relied on pensions, while 22.5 percent relied on public unemployment assistance and 21.1 percent on savings and other kinds of assets.

Of the 3.74 million people out of work, 2.38 million said they had not made any effort to improve their vocational capabilities in the past 12 months.

Those in the category aged between 35 and 44 said the reason for the lack of effort was mainly because they couldn't afford the expense of taking vocational courses or training programs.
