According to the TT news agency, the Board expects some 45,000 people to apply for asylum in 2013, 9,000 lower than it had previously anticipated.
The Board says that the fall is in part due to stricter controls at the outer boarders of the European Union, making it harder for refugees fleeing conflict in Afghanistan, Syria and elsewhere to reach Sweden.
However, political instability contributed to a jump in applications last year, when the Migration Board received 43,887, compared to 29,648 in 2011.
The Board is currently conducting an assessment of the situation in Syria. This could make it easier for Syrian asylum seekers to gain permanent residency in Sweden, as opposed to being given temporary permission to stay.
The number of asylum applications is projected to reach 48,000 next year.
