The fact was revealed via a Freedom of Information request - but it does not reveal who the offenders are, exactly what they have done or where they stay.
Despite this Hugh Henry MSP told the Barrhead News he thinks it is right information on the number of sex offenders living in the area should be made available to the public.
He said: "I don't have a problem with information being released and I do think it is incumbent on police and social work departments to make sure that every possible step is taken to protect the public when a sex offender is released.
"I understand people can't be held indefinitely but at the same time we need to make sure every necessary step is taken to protect the public.
"It's not always the volume, it's sometimes down to the danger an individual poses and that's where the authorities need to make sure they are doing everything that they are responsible for."
