The deterioration of labour market conditions in Lithuania has resulted in a 30% drop in total immigration in 2009, to 6 500, and a parallel increase in emigration. The number of registered departures increased by almost 30% to 22 000 persons. Preliminary data for 2010 show that immigration continued to decrease (5 200 entries recorded in 2010) and registered emigration increased strongly over that period, a total of 83 600 persons, but this seems, but this seems mainly due to the obligation to deregister to avoid payment into the compulsory health insurance. These official figures only reflect emigrants who leave the country for a period longer than one year and report their departure. The Labour Force Survey provides some estimates on the undeclared emigration. In 2009, undeclared emigration was estimated to have risen again, accounting for a third of the total outflows.
