Concerned protestors reportedly gathered in the centre of Stockholm on Saturday to protest against the measures which include forcing child asylum seekers to prove their age.
Simultaneous demonstrations also took place in 14 other Swedish towns and cities including Umeå, Karlstad and Jönköping, Swedish news agency TT reported.
The protests were organised by the Vu star inte ut (We can’t stand it) group which has called for the end to forced deportations and more humane conditions for asylum seekers.
New legislation, which came into force in July, is supposed to be in place for three years and aims to reduce the number of refugees arriving in the country from the Middle East down to more manageable levels.
The country, which has a population of 10m, took in 160,000 asylum seekers last year - a ratio of 1,667 asylum applications per 100,000 people in the local population.
The EU average is 260 applications per 100,000 people.

The law means Sweden can offer a three-year residence permit to refugees whose asylum claims it deems genuine instead of a permanent right to remain.
It also restricts the rights of refugees to come to Sweden if they already have family living there.
One particular sticking point for campaigners is a deal agreed with the Afghan government earlier this month to repatriate people from the country who claim asylum in Sweden.
But 300 Swedish teachers wrote an open letter to the government in the newspaper Svenska Dagbladet saying it undermines the education of children who have already suffered terribly.
It said: “A few days ago one of our pupils received his deportation order. He is 15. In three years he will be deported to Afghanistan. He is far from alone and now risks spending years of his development at war, in refugee camps, underground, or on the run.
“It would be shameful to deport children and youths en masse to Afghanistan. What is a government even worth if if is incapable of protecting children in its own country and giving them hope for the future?”
