businesses and families on which

[ademoglu]

Hello,

''The global financial market has ceased to function, putting in danger the necessary flow of money to businesses and families on which all of us depend in our daily lives.''

I'd like to ask why 'which' is used in the above sentence after 'businesses and families.' Without 'families', I, of course, would put 'which' but cannot associate it with 'families.' Could you please enlighten me?

Thanks.

"Which" refers to "the flow of money to businesses and families".
