Unclean spirits are demonic powers that afflict the soulish nature of man. They are responsible for immoral acts, unclean thoughts, temptations and other strategies of satan used to bind men and women.
When satan controls individuals with unclean spirits, he can also operate in homes, churches, and entire nations as these groups are composed of individuals. This is how satan works in the various levels of structure in society.

25 And Jesus rebuked him, saying, Hold thy peace, and come out of him.
