The figure for January represents a four per cent drop on December's figures. Most of the civilian victims were killed by roadside bombs, the favoured weapon of the Islamist militias.
'Unfortunately one hundred of our innocent civilian countrymen and women were martyred in January and 148 others were wounded in various attacks,' Zemarai Bashiri, interior ministry spokesman said in his weekly press conference in Kabul.
A total of 2,400 civilians were killed in 2010.
'Police causalities jumped by 21 percent in the first month of 2011, unfortunately,' Bashari said.
Afghan security forces killed 286 armed insurgents in January, Bahsiri said.
'Security forces were able to detain 559 suspected militants involved in destructive attacks last month. Also 574 bombs were defused by security forces all over in Afghanistan,' the interior ministry official added.
